D.gnu - OS X, gdc and opengl

reply Brad Beveridge <brad nowhere.org> writes:
Hi all, I'm wanting to play with D and openGL on a Mac.  I've managed to 
compile vanilla GCC sources with the GDC patch, and can happily compile 
the example app.
However, I can't figure out how to link against opengl libraries. 
Apple's version of GCC has a -framework option, which GDC and vanilla 
GCC don't recognise.
My next step was to try to compile Apple's GCC tree with the D patches, 
and have run into the following error
../../gcc3/gcc/d/d-lang.cc: In function `bool 
d_mark_addressable(tree_node*)':
../../gcc3/gcc/tree.h:2944: error: too few arguments to function `void 
put_var_into_stack(tree_node*, int)'
../../gcc3/gcc/d/d-lang.cc:898: error: at this point in file
../../gcc3/gcc/d/d-lang.cc: At global scope:
../../gcc3/gcc/d/d-lang.cc:1358: error: invalid conversion from 
`rtx_def*(*)(tree_node*, rtx_def*, machine_mode, int, rtx_def**)' to 
`rtx_def*(*)(tree_node*, rtx_def*, machine_mode, int)'

I don't mind banging my head against the wall to try and fix either of 
these problems, but if someone has already figured it out, well that 
would be nice :)

So,
1) Is there a way to link vanilla gcc+gdc with opengl on Mac OSX?
2) Is there a way around the error I get when compiling Apple's GCC?

Also, I tried to enable --altivec on the vanilla GCC build and the build 
failed due to some "forcecpusubtype_ALL" option missing - am I missing 
something here?

Thanks much
Brad

The linker *does* recognize it, so you can use -Wl,-framework,-OpenGL

I have done a patch to add -framework support and some other
Mac stuff to the GDC build, but it has not been released yet...
(and it probably won't be for another weeks/months, either)

As you found out, this does not work...
Apple's GCC tree has *tons* of patches.

Yeah, that AltiVec doesn't work either? :-P

You can write a function in C (*not* using Altivec registers outwards),
compile it with Apple's compiler and then link it with the D programs.
The same song-and-dance routine is required for using PPC assembler...

Make that -Wl,-framework,OpenGL ... (silly typo snuck in)

As in:
LDFLAGS=-Wl,-framework,OpenGL -Wl,-framework,GLUT -lobjc

Thanks for that Anders.  I am recompiling gdc now - why did I delete it! :)
I don't quite understand what you are saying with the linker recognising 
-framework, could you please post a trivial example of how to compile & 
link a D file that needs OpenGL?  I tried

opengltestd: opengltest.d
gdc $< -I../SDL -L/sw/lib -lSDLmain -lSDL -framework OpenGL -lpthread 
-lGL -lglut -lGLU -o $ 

And had no luck - google also didn't turn up any hints for me.

Thanks

"-framework" goes to the compiler, which will choke on the unrecognized
option. By using "-Wl", you can pass whatever you want to the linker...


 opengltestd: opengltest.d
 gdc $< -I../SDL -L/sw/lib -lSDLmain -lSDL -framework OpenGL -lpthread 
 -lGL -lglut -lGLU -o $ 


You did not say that you wanted to use SDL, which is lots more fun since
it is written in Objective-C and requires a patched SDLmain library...

But anyway, the libraries are:
LDFLAGS_GL=-Wl,-framework,OpenGL -Wl,-framework,GLUT -lobjc
LDFLAGS_SDL=-Wl,-framework,SDL -Wl,-framework,Cocoa -Lsdl -lSDLmain_d

On Linux, they would instead be:
LDFLAGS_GL=-lGL -lGLUT
LDFLAGS_SDL=-lSDL

I should have an updated example up sometime next week.
The old example does not compile at the moment, but when
it did it was running both GL "gears" and SDL "testbitmap".

Sorry for being so dense - I seem to be close, but not quite there yet
Here is my compile command

gdc opengltest.d -o opengltestd -I../SDL -L/sw/lib -Wl,-framework,OpenGL 
-Wl,-framework,GLUT -lobjc -lSDL -Wl,-framework,Cocoa -lSDLmain
/usr/bin/ld: Undefined symbols:
_SDL_main
collect2: ld returned 1 exit status

I couldn't use your command as I got this error
gdc opengltest.d -o opengltestd -I../SDL -L/sw/lib -Wl,-framework,OpenGL 
-Wl,-framework,GLUT -lobjc -Wl,-framework,SDL -Wl,-framework,Cocoa 
-lSDLmain_d
/usr/bin/ld: can't locate framework for: -framework SDL

I've tried to get the OSX SDL framework installed, but to no avail.  The 
SDL source fails in the ./configure stage (threading unsupported!), and 
the SDL OSX devel libraries specifically say the framework is not 
installed & to get it from the sources.

Any help is much appreciated.

Cheers
Brad

You need a special version of the SDLmain, that initializes the D 
runtime. It also needs to be called from your "main(char[][] args)"


 Any help is much appreciated.


SDL code will come later, just use plain GLUT in the meantime ?

boohoo, sob! :)
Yeah, maybe I'm jumping in just a tad deep.  I'll back off and play with 
GLUT.  I probably ought to become familiar with the Apple way of doing 
development also.  All of my linux play apps are SDL based, so hopefully 
when I get a little smarter they'll all "Just Work" on OSX.

Thanks for the help Anders

Seems like the next GDC version will be a while,
and so will a coherent download of SDL/GL for Mac.

If you're anxious to get started, see my CVS rep.
(or email me privately, it shouldn't be that hard)

Thanks Anders.  I don't mind waiting :)  I've got plenty to do to figure

I played with your CVS tree last night, and managed to get the testgl 
program working fine.  So I can start playing with my own SDL/D/MacOS 
stuff now :)
Thanks for the good work.  I take it the SDL stuff you've done is open 
source, or somesuch?
Also, do you know if it is possible to profile GDC apps with Shark? 
I've heard a lot about Shark & I think I may play with that next.

It's under the same license as the C headers, i.e. LGPL for SDL

Should be, just that the D name mangling is a little "strange"...

In my own setup, I have Apple's original stuff living under /usr,

The current GDC does not really fit into the /usr or /sw hierarchies,
since it might cause conflicts with the default GCC compilers used ?

And it also makes it easier to uninstall, without a package manager.

Thanks for all the great tips and help Anders.  As you might have 
guessed, I am new (about 5 days) to the OSX world.  I'm expecting to 
make quite a few bloopers yet :)

What is the default version for GDC on OS X (ie, linux, Win32, etc) - 
and how should I find out (apart from asking here :)

While the polished version has not been released, the raw patches have:
http://dstress.kuehne.cn/raw_results/mac-OS-X-10.3.7_gdc-0.10-patch/
gcc-3.3.5-framework-headers.patch
gcc-3.3.5-framework-linker.patch
gdc-0.8-framework.patch

taken from the original Apple source code for Xcode version 1.1, at:
http://www.opensource.apple.com/darwinsource/DevToolsDec2003/gcc-1495/
(haven't checked if they updated the patches in Xcode 1.2 or 1.5, but)
