The latest SVN version has fixes that will allow GDC to build with 
psptoolchain (and MIPS, in general).  I do not have a PSP, so I cannot

Hi, 
I was intrigued enough to have another go at compiling GDC for the PSP (my
previous attempt half a year ago did not get me very far), and I can say that
at least the toolchain builds fine (for D 1.0) with a working compiler and a
libgphobos. (When I enabled D 2.0, the toolchain build stopped with compiler
errors)

Here's what my psp-gdc -v produces:

Using built-in specs.
Target: psp
Configured with: ../configure --prefix=/pspdev --target=psp
--enable-languages=c,d,c++ --with-newlib --enable-cxx-flags=-G0
--disable-libssp --enable-static --disable-shared
Thread model: single
gcc version 4.1.0 20060228 ( gdc 0.24, using dmd 1.030) (PSPDEV 20060507)

BTW you can also see the configure flags I used.

I wanted to see if I could get a working executable. So my test was, to have D
function be called from a C main function (because the PSP sdk has some special
initialization macros that I guess need to be defined to get a working
executable). However when linking the program I got a lot of linker errors,
originating from libphobos/std/math.d and libphobos/gcc/cbridge_math.c. My
guess is that these come from the lack of double support on the psp toolchain.
Could that be the case, or is it some kind of misconfiguration? Also is there
some way of fixing this?

Thanks!

Here is the test program:
----------------------------------
testd.d:
import std.stdio;

extern(C) void dfunc()
{
        printf("Hello from D");
}

----------------------------------
#include <pspkernel.h>
#include <stdio.h>
PSP_MODULE_INFO("test", 0, 1, 1);
PSP_MAIN_THREAD_ATTR(THREAD_ATTR_USER | THREAD_ATTR_VFPU);
extern void dfunc();
int main(int argc, char *argv[])
{
        printf("Hello World\n");
        dfunc();
        return 0;
}

Thanks for listing the compile flags. I successfully built an executable 
but there was no libgphobos.a appearing--which prevented me from 
instantiating any classes or structs in my test example (which operates 
similar to yours--an extern'd d function called from C).

Would it be possible to use a stripped down version of Tango or Phobos, 
perhaps something that has the base type/classinfo and memory management 
stuff and leave the rest alone? I just need auto memory management and 
classes and I can use all the sce* psp sdk functions for other things.

BTW, you might want to use pspDebugScreenPrintf and pspDebugScreenInit 
instead of printf for the C code. Last time I checked, they are very 
different and printf doesn't work.

Nice to hear, do you mind writing a short howto?

Maybe on the news-group or on http://www.prowiki.org/wiki4d.
For others who want to follow the path.

Hi,

Actually my company is actually working on generating a cross-compiler

Now I agree with you it would be great if we could compile with no

But more generally we are working on a framework called Gynoid that

There something I don't understand in your sentence below :

 Would it be possible to use a stripped down version of Tango orPhobos,
 perhaps something that has the base type/classinfo and memory management
 stuff and leave the rest alone? I just need auto memory management and
 classes and I can use all the sce* psp sdk functions for other things.

I thought that memory management was part of the language and not in 
phobos lib, in this case I really agree that it would be interesting to 
remove libphobos dependency and to allow developpers to developp their 
own lib.







John Grindstaff a �crit :
 Thanks for listing the compile flags. I successfully built an executable 
 but there was no libgphobos.a appearing--which prevented me from 
 instantiating any classes or structs in my test example (which operates 
 similar to yours--an extern'd d function called from C).

 BTW, you might want to use pspDebugScreenPrintf and pspDebugScreenInit 
 instead of printf for the C code. Last time I checked, they are very 
 different and printf doesn't work.

 Hi, I was intrigued enough to have another go at compiling GDC for the 
 PSP (my previous attempt half a year ago did not get me very far), and 
 I can say that at least the toolchain builds fine (for D 1.0) with a 
 working compiler and a libgphobos. (When I enabled D 2.0, the 
 toolchain build stopped with compiler errors)

 Here's what my psp-gdc -v produces:

 Using built-in specs.
 Target: psp
 Configured with: ../configure --prefix=/pspdev --target=psp 
 --enable-languages=c,d,c++ --with-newlib --enable-cxx-flags=-G0 
 --disable-libssp --enable-static --disable-shared
 Thread model: single
 gcc version 4.1.0 20060228 ( gdc 0.24, using dmd 1.030) (PSPDEV 20060507)

 BTW you can also see the configure flags I used.

 I wanted to see if I could get a working executable. So my test was, 
 to have D function be called from a C main function (because the PSP 
 sdk has some special initialization macros that I guess need to be 
 defined to get a working executable). However when linking the program 
 I got a lot of linker errors, originating from libphobos/std/math.d 
 and libphobos/gcc/cbridge_math.c. My guess is that these come from the 
 lack of double support on the psp toolchain. Could that be the case, 
 or is it some kind of misconfiguration? Also is there some way of 
 fixing this?

 Thanks!

 for other things.

 BTW, you might want to use pspDebugScreenPrintf and pspDebugScreenInit 
 instead of printf for the C code. Last time I checked, they are very 
 different and printf doesn't work.

 Hi, I was intrigued enough to have another go at compiling GDC for

 Here's what my psp-gdc -v produces:

 BTW you can also see the configure flags I used.

 I wanted to see if I could get a working executable. So my test was, 
 to have D function be called from a C main function (because the PSP 
 sdk has some special initialization macros that I guess need to be 
 defined to get a working executable). However when linking the 
 program I got a lot of linker errors, originating from 
 libphobos/std/math.d and libphobos/gcc/cbridge_math.c. My guess is 
 that these come from the lack of double support on the psp toolchain. 
 Could that be the case, or is it some kind of misconfiguration? Also 
 is there some way of fixing this?

 Thanks!

 Hi,

 Sorry to participate to this discussion but we may have some common goals.
 Actually my company is actually working on generating a cross-compiler
 running on windows CE device.
 We have almost finished, there are some minors bugs but it's pretty close.
 Now I agree with you it would be great if we could compile with no
 dependencies to libphobos and actually it's possible if you pass
 -nophoboslib to linker.
 But more generally we are working on a framework called Gynoid that
 targets embedded platforms(Windows CE, Symbian, Darwin) and it would be
 great if we could add support for PSP...

 There something I don't understand in your sentence below :

 I thought that memory management was part of the language and not in
 phobos lib, in this case I really agree that it would be interesting to
 remove libphobos dependency and to allow developpers to developp their
 own lib.

The Garbage Collector, threading plus some language support routines (array
operations in particular) are part of libphobos. Passing -nophoboslib
generally means you need to pass something else with enough functionality.

You probably don't want to do that yourself, as parts of it are very
dependent on the compiler (or the other way round).

With Tango, whatever you want to achieve, will be easier. In Tango, the
tango.* namespace/imports (roughly equivalent to std.* in Phobos) is a
separate library, and the runtime (language support) one library (typically
called libtango-base-* where the * is the compiler). Going further, this
runtime is cleanly divided into 3 separate parts, the GC, compiler specific
stuff (Tango currently has support for GDC and DMD), and common stuff
(non-GC functionality common for all compilers, like threading + some
smaller features not present in Phobos). If one for some reason do wish to
replace parts of the runtime, this will be much easier with this setup. In
Tango, the interface provided by the runtime is well specified, and
Tangobos (a Phobos port) in addition to Tango works on top of it.

Thanks John, for the pointer on libm, that indeed fixed my linker errors.

I've managed to get the libgphobos runtime working on the PSP, and the examples
I tried from http://www.dsource.org/projects/tutorials/wiki appear to work ! 

I had to make a tiny change in libgphobos though. I've had to rename the
libgphobos' c-startup function (phobos/internal/cmain.d) (which jumps into
d-main) into a name other than "main" so that it can be called from the PSPSDK
main. 

For those interested I've included my patch on libphobos as well as a simple
PSP Application (Makefile included). 
http://www.mediafire.com/?xlizxgmm0vl
Obviously for this to work you need to patch and build libgphobos.

Any people interested in this, let me know how you get on.

I've also had a go at compiling tango, but it doesn't look like a trivial task.
Initially the psp's arch is not detected by autoconf, and even by hacking the
detection, it still stops long before compiling anything. Perhaps someone with
more insight into tango can offer advice on how to port it.

BTW John, I haven't encountered any problems with printfs in my code so far (in
this or other unrelated projects). Perhaps you aren't using the latest version
of the SDK ?

 Thanks for listing the compile flags. I successfully built an executable

 instantiating any classes or structs in my test example (which operates 
 similar to yours--an extern'd d function called from C).
 
 Would it be possible to use a stripped down version of Tango or Phobos, 
 perhaps something that has the base type/classinfo and memory management

The configure part is probably just something not having been merged yet,
unfortunately I don't think I'm the right man to solve that particular

Hi Lars,

First of all here's a patch to add the psp as a target to the
configure script. I extracted it from the PSP toolchain patches. This
patch is against svn tango-0.99.7, but it's really simple and probably
would work on other versions as well.
I applied it in lib/compiler/gdc (with -p1)

Now having done that. I tried to run 'build-gdc-x.sh psp', but
unfortunately it makes configure think that my host is also a psp.

A minor problem is that even though I'm cross compiling configure
assumes that the "gdc" the executable is DMD, so I bypassed that with an

 BTW John, I haven't encountered any problems with printfs in my code so far
(in this or other unrelated projects). Perhaps you aren't using the latest
version of the SDK ?

 Thanks for listing the compile flags. I successfully built an executable 
 but there was no libgphobos.a appearing--which prevented me from 
 instantiating any classes or structs in my test example (which operates 
 similar to yours--an extern'd d function called from C).

 Would it be possible to use a stripped down version of Tango or Phobos, 
 perhaps something that has the base type/classinfo and memory management 
 stuff and leave the rest alone? I just need auto memory management and 
 classes and I can use all the sce* psp sdk functions for other things.

 BTW, you might want to use pspDebugScreenPrintf and pspDebugScreenInit 
 instead of printf for the C code. Last time I checked, they are very 
 different and printf doesn't work.

 Hi, 
 I was intrigued enough to have another go at compiling GDC for the PSP (my
previous attempt half a year ago did not get me very far), and I can say that
at least the toolchain builds fine (for D 1.0) with a working compiler and a
libgphobos. (When I enabled D 2.0, the toolchain build stopped with compiler
errors)

 Here's what my psp-gdc -v produces:

 Using built-in specs.
 Target: psp
 Configured with: ../configure --prefix=/pspdev --target=psp
--enable-languages=c,d,c++ --with-newlib --enable-cxx-flags=-G0
--disable-libssp --enable-static --disable-shared
 Thread model: single
 gcc version 4.1.0 20060228 ( gdc 0.24, using dmd 1.030) (PSPDEV 20060507)

 BTW you can also see the configure flags I used.

 I wanted to see if I could get a working executable. So my test was, to have D
function be called from a C main function (because the PSP sdk has some special
initialization macros that I guess need to be defined to get a working
executable). However when linking the program I got a lot of linker errors,
originating from libphobos/std/math.d and libphobos/gcc/cbridge_math.c. My
guess is that these come from the lack of double support on the psp toolchain.
Could that be the case, or is it some kind of misconfiguration? Also is there
some way of fixing this?

 Thanks!

 Here is the test program:
 ----------------------------------
 testd.d:
 import std.stdio;

 extern(C) void dfunc()
 {
         printf("Hello from D");
 }

 ----------------------------------
 #include <pspkernel.h>
 #include <stdio.h>
 PSP_MODULE_INFO("test", 0, 1, 1);

 extern void dfunc();
 int main(int argc, char *argv[])
 {
         printf("Hello World\n");
         dfunc();
         return 0;
 }

 I've also had a go at compiling tango, but it doesn't look like a 
 trivial task. Initially the psp's arch is not detected by autoconf, 
 and even by hacking the detection, it still stops long before 
 compiling anything. Perhaps someone with more insight into tango can 
 offer advice on how to port it.

 BTW John, I haven't encountered any problems with printfs in my code 
 so far (in this or other unrelated projects). Perhaps you aren't using 
 the latest version of the SDK ?

 Thanks for listing the compile flags. I successfully built an 
 executable but there was no libgphobos.a appearing--which prevented 
 me from instantiating any classes or structs in my test example 
 (which operates similar to yours--an extern'd d function called from C).

 Would it be possible to use a stripped down version of Tango or 
 Phobos, perhaps something that has the base type/classinfo and memory 
 management stuff and leave the rest alone? I just need auto memory 
 management and classes and I can use all the sce* psp sdk functions 
 for other things.

 BTW, you might want to use pspDebugScreenPrintf and 
 pspDebugScreenInit instead of printf for the C code. Last time I 
 checked, they are very different and printf doesn't work.

 Hi, I was intrigued enough to have another go at compiling GDC for 
 the PSP (my previous attempt half a year ago did not get me very

 1.0) with a working compiler and a libgphobos. (When I enabled D 
 2.0, the toolchain build stopped with compiler errors)

 Here's what my psp-gdc -v produces:

 Using built-in specs.
 Target: psp
 Configured with: ../configure --prefix=/pspdev --target=psp 
 --enable-languages=c,d,c++ --with-newlib --enable-cxx-flags=-G0

 Thread model: single
 gcc version 4.1.0 20060228 ( gdc 0.24, using dmd 1.030) (PSPDEV 
 20060507)

 BTW you can also see the configure flags I used.

 I wanted to see if I could get a working executable. So my test was, 
 to have D function be called from a C main function (because the PSP 
 sdk has some special initialization macros that I guess need to be 
 defined to get a working executable). However when linking the 
 program I got a lot of linker errors, originating from 
 libphobos/std/math.d and libphobos/gcc/cbridge_math.c. My guess is 
 that these come from the lack of double support on the psp 
 toolchain. Could that be the case, or is it some kind of 
 misconfiguration? Also is there some way of fixing this?

 Thanks!

 Here is the test program:
 ----------------------------------
 testd.d:

 extern(C) void dfunc()

         printf("Hello from D");

Assuming the C main() in libgphobos is not actually interfering with the 
  PSP SDK (e.g., duplicate symbols), you do not have to rename it.  You 
can call the following function which exists for exactly this purpose.

extern (C) int _d_run_Dmain(int argc, char **argv);

 Thanks John, for the pointer on libm, that indeed fixed my linker errors.
 
 I've managed to get the libgphobos runtime working on the PSP, and the
examples I tried from http://www.dsource.org/projects/tutorials/wiki appear to
work ! 
 
 I had to make a tiny change in libgphobos though. I've had to rename the
libgphobos' c-startup function (phobos/internal/cmain.d) (which jumps into
d-main) into a name other than "main" so that it can be called from the PSPSDK
main. 
 
 For those interested I've included my patch on libphobos as well as a simple
PSP Application (Makefile included).

 Thanks John, for the pointer on libm, that indeed fixed my linker errors.

 I've managed to get the libgphobos runtime working on the PSP, and the 
 examples I tried from http://www.dsource.org/projects/tutorials/wiki 
 appear to work !
 I had to make a tiny change in libgphobos though. I've had to rename 
 the libgphobos' c-startup function (phobos/internal/cmain.d) (which 
 jumps into d-main) into a name other than "main" so that it can be 
 called from the PSPSDK main.
 For those interested I've included my patch on libphobos as well as a 
 simple PSP Application (Makefile included). 
 http://www.mediafire.com/?xlizxgmm0vl
 Obviously for this to work you need to patch and build libgphobos.

 Any people interested in this, let me know how you get on.

 I've also had a go at compiling tango, but it doesn't look like a 
 trivial task. Initially the psp's arch is not detected by autoconf, 
 and even by hacking the detection, it still stops long before 
 compiling anything. Perhaps someone with more insight into tango can 
 offer advice on how to port it.

 BTW John, I haven't encountered any problems with printfs in my code 
 so far (in this or other unrelated projects). Perhaps you aren't using 
 the latest version of the SDK ?


 John Grindstaff Wrote:

 Thanks for listing the compile flags. I successfully built an 
 executable but there was no libgphobos.a appearing--which prevented 
 me from instantiating any classes or structs in my test example 
 (which operates similar to yours--an extern'd d function called from C).

 Would it be possible to use a stripped down version of Tango or 
 Phobos, perhaps something that has the base type/classinfo and memory 
 management stuff and leave the rest alone? I just need auto memory 
 management and classes and I can use all the sce* psp sdk functions 
 for other things.

 BTW, you might want to use pspDebugScreenPrintf and 
 pspDebugScreenInit instead of printf for the C code. Last time I 
 checked, they are very different and printf doesn't work.

 Hi, I was intrigued enough to have another go at compiling GDC for 
 the PSP (my previous attempt half a year ago did not get me very 
 far), and I can say that at least the toolchain builds fine (for D 
 1.0) with a working compiler and a libgphobos. (When I enabled D 
 2.0, the toolchain build stopped with compiler errors)

 Here's what my psp-gdc -v produces:

 Using built-in specs.
 Target: psp
 Configured with: ../configure --prefix=/pspdev --target=psp 
 --enable-languages=c,d,c++ --with-newlib --enable-cxx-flags=-G0 
 --disable-libssp --enable-static --disable-shared
 Thread model: single
 gcc version 4.1.0 20060228 ( gdc 0.24, using dmd 1.030) (PSPDEV 
 20060507)

 BTW you can also see the configure flags I used.

 I wanted to see if I could get a working executable. So my test was, 
 to have D function be called from a C main function (because the PSP 
 sdk has some special initialization macros that I guess need to be 
 defined to get a working executable). However when linking the 
 program I got a lot of linker errors, originating from 
 libphobos/std/math.d and libphobos/gcc/cbridge_math.c. My guess is 
 that these come from the lack of double support on the psp 
 toolchain. Could that be the case, or is it some kind of 
 misconfiguration? Also is there some way of fixing this?

 Thanks!

 Here is the test program:
 ----------------------------------
 testd.d:
 import std.stdio;

 extern(C) void dfunc()
 {
         printf("Hello from D");

Build instructions

First of all I'm running OSX Leopard on a PowerPC, so what you need to
do may vary, not by much on a Unix system but potentially a lot on Windows.

I assume you have the latest and complete psp toolchain. If not I
suggest you try downloading & installing a prebuilt one or preferably
use the "psptoolchain" build scripts found on:
svn://svn.ps2dev.org/psp/trunk/psptoolchain

Ok, here we go:

1. Make a temporary directory for your build
mkdir pspd
cd pspd

2. Setup environment paths
export PSPDEV=/the/path/where/the/pspsdk/is/already/installed
export PATH=$PATH:$PSPDEV/bin




export C_INCLUDE_PATH="/opt/local/include"
export CPLUS_INCLUDE_PATH="/opt/local/include"
export LIBRARY_PATH="/opt/local/lib"

3. Download and unpack gcc
wget --continue ftp://ftp.gnu.org/pub/gnu/gcc/gcc-4.1.0/gcc-4.1.0.tar.bz2

tar -xvjf gcc-4.1.0.tar.bz2

4. Download and apply psp toolchain patches to gcc
svn export
svn://svn.ps2dev.org/psp/trunk/psptoolchain/patches/gcc-4.1.0-PSP.patch
cd gcc-4.1.0
patch -p1 <../gcc-4.1.0-PSP.patch

5. Download and setup gdc
cd gcc



svn co https://dgcc.svn.sourceforge.net/svnroot/dgcc/trunk/d

cd ..


./gcc/d/setup-gcc.sh --d-language-version=1

5.5 Optional step, for those compiling GCC under Leopard/PowerPC. Apply a patch
to fix some GCC compiler errors

cd gcc/config/rs6000/
wget "http://trac.macports.org/attachment/ticket/13191/gcc_patch?format=raw"
-Oleopard_ppc.patch
patch -p1 <leopard_ppc.patch
cd ../../../


6. Configure, build, and install gcc (gdc & libgphobos included)


mkdir build-psp
cd build-psp


../configure --prefix="$PSPDEV" --target="psp" --enable-languages="c,d,c++"
--with-newlib --enable-cxx-flags="-G0" --disable-libssp --enable-static
--disable-shared


CFLAGS_FOR_TARGET="-G0" make


make install

And that should be enough to get a funcional GCC with D/libgphobos

As far as my small libgphobos patch is concerned, I agree that it might not be
necessary. However given the temperamental behaviour of the linker (especially
when it comes to the order of the PSPSDK libraries) I removed the extra
definition of main, to make sure that if no main is declared a linker error
would be raised. 
At any rate it works fine without the change.

Have fun !

Hi Kostas,

I am interested in your PSP port and I would like to add it to my cegdc

I am working on scripts to build differents versions, something like :


sh build-gdc.sh --target psp or

 Hi Kostas,
 
 I am interested in your PSP port and I would like to add it to my cegdc 
 (gdc for window CE), it could be interesting to have a gcc for embedded 
 targets.
 I am working on scripts to build differents versions, something like :
 
 
 sh build-gdc.sh --target psp or
 sh build-gdc.sh --target arm-mingw32ce
 ...


Hi Vince,

Personally I don't have a problem. Building, however, the full psp 
toolchain and sdk for scratch involves many more steps. The method I 
described is just for rebuilding the toolchain with D support. The 
difficult work was done the pspdev community.
To get idea of what is involved in building the entire toolchain/sdk 
from scratch have a look at svn://svn.ps2dev.org/psp/trunk/psptoolchain 
especially the scripts directory. (binutils, gcc stage1, pspsdk stage1, 
newlib, gcc stage2, psp sdk stage2, etc)

However, if you are just interested in making easy for people to build 
just gdc given a working toolchain, then that's ok.

Thanks very much. That actually worked and libgphobos.a appeared where 
it should (in psp next to libiberty, libc++ or whatever).

Are you using garbage collection without calling Phobos's Cmain 
function? I thought it inits GC with gc_init() so how is that possible?

I wonder if it is possible to write a C-source function wrapper around 
the PSP_MODULE_MACRO so that one could use a D main function (as normal)?

 Build instructions
 
 First of all I'm running OSX Leopard on a PowerPC, so what you need to
 do may vary, not by much on a Unix system but potentially a lot on Windows.
 
 I assume you have the latest and complete psp toolchain. If not I
 suggest you try downloading & installing a prebuilt one or preferably
 use the "psptoolchain" build scripts found on:
 svn://svn.ps2dev.org/psp/trunk/psptoolchain
 
 Ok, here we go:
 
 1. Make a temporary directory for your build
 mkdir pspd
 cd pspd
 
 2. Setup environment paths
 export PSPDEV=/the/path/where/the/pspsdk/is/already/installed
 export PATH=$PATH:$PSPDEV/bin
 



 export C_INCLUDE_PATH="/opt/local/include"
 export CPLUS_INCLUDE_PATH="/opt/local/include"
 export LIBRARY_PATH="/opt/local/lib"
 
 3. Download and unpack gcc
 wget --continue ftp://ftp.gnu.org/pub/gnu/gcc/gcc-4.1.0/gcc-4.1.0.tar.bz2
 
 tar -xvjf gcc-4.1.0.tar.bz2
 
 4. Download and apply psp toolchain patches to gcc
 svn export
 svn://svn.ps2dev.org/psp/trunk/psptoolchain/patches/gcc-4.1.0-PSP.patch
 cd gcc-4.1.0
 patch -p1 <../gcc-4.1.0-PSP.patch
 
 5. Download and setup gdc
 cd gcc

 

 svn co https://dgcc.svn.sourceforge.net/svnroot/dgcc/trunk/d
 
 cd ..
 

 ./gcc/d/setup-gcc.sh --d-language-version=1
 
 5.5 Optional step, for those compiling GCC under Leopard/PowerPC. Apply 
 a patch to fix some GCC compiler errors
 
 cd gcc/config/rs6000/
 wget 
 "http://trac.macports.org/attachment/ticket/13191/gcc_patch?format=raw" 
 -Oleopard_ppc.patch
 patch -p1 <leopard_ppc.patch
 cd ../../../
 
 
 6. Configure, build, and install gcc (gdc & libgphobos included)


 mkdir build-psp
 cd build-psp
 

 ../configure --prefix="$PSPDEV" --target="psp" 
 --enable-languages="c,d,c++" --with-newlib --enable-cxx-flags="-G0" 
 --disable-libssp --enable-static --disable-shared
 

 CFLAGS_FOR_TARGET="-G0" make
 

 make install
 
 And that should be enough to get a funcional GCC with D/libgphobos
 
 As far as my small libgphobos patch is concerned, I agree that it might 
 not be necessary. However given the temperamental behaviour of the 
 linker (especially when it comes to the order of the PSPSDK libraries) I 
 removed the extra definition of main, to make sure that if no main is 
 declared a linker error would be raised. At any rate it works fine 
 without the change.
 
 Have fun !

 You can call the following function which exists for exactly this

I think it's better if the PSP_* macros are maintained in a user .c file 
that gets compiled along with the user application.

For example:

pspconfig.c:
#include <pspkernel.h>
PSP_MODULE_INFO("my-dmodule", 0, 1, 1);
PSP_MAIN_THREAD_ATTR(THREAD_ATTR_USER | THREAD_ATTR_VFPU);
PSP_HEAP_SIZE_MAX();

Note that no c main function is necessary, just the macros.

These declarations do vary per application, and give the option of 
customizing things (thread attributes, kernel/usermode, heap size 
configuration, etc.).

That's how I have it setup now, but someone reminded me that GDC 
actually supports the old gcc-style of inline assembly. So it _may_ 
actually be possible to port those macros to D after all. I'd rather not 
try it though, right now I am busy wrestling with png.h trying to 
convert it to D, but it is the worst C header file I've ever tried to 
look at...

I have official psp-gcc sources (patches to gcc), and since they are  
covered by GPL I think it's ok to share them. Will it help make better  
psp-gdc?

Thanks to Kostas advice, I am able to use D on GDC and posted an example 
of a PSP app that uses D's real main function (still with a minor glue C 
source file).

Link: http://forums.qj.net/showthread.php?t=142864

Right now I'm porting all of the PSP SDK's header files to D. I just 
finished with pspgu.h, look forever with its 1000+ lines but most of it 
is comments anyway.
