D - SDL, OpenGL, and TinyPTC

I have upgraded my DMC installation and installed the latest (0.36) DMD alpha.
All of the code in \samples\d compiles and executes just fine.

I am now trying to use the various ported modules from the DedicateD site,
starting with SDL, OpenGL, and TinyPTC.

1. I created a new directory \dmd\import -- somehow \dmd\include didn't seem
right since we don't use #include.  

2. I unzipped all of the packages into \dmd\import.

3. I moved \dmd\import\*.lib into \dmd\lib.

4. I modified \dmd\bin\sc.ini so that the flags variable included my import
directory.

I can now compile testgl, testbitmap, and voxel, but I keep getting linker
errors.  For the SDL/GL examples, the linkage errors sound like it can't find
SDL.lib and OpenGL32.lib.  TinyPTC (library that voxel uses) doesn't come with a
library, it is just an imported module.  I have downloaded the actual Windows
TinyPTC distribution, thinking that it might have a library or DLL I needed, but
it is all source code.

So I have two questions.  They probably arise from ignorance of the linker,
since I use DMC through SC, and it finds everything for me.

1. How do I get testgl and testbitmap to link to the libraries that are
available in \dmd\lib?  SC.INI is configuring the LIB variable correctly to
include this path, because that is where the phobos library is, and the other
programs are linking properly to phobos.

2. What am I doing wrong with the voxel demo?  It shouldn't be a library linkage
problem, because there isn't a library.  The error I get is:

voxel.obj(voxel)
Error 42: Symbol Undefined _Dtinyptc_ptc_open_FAaiiZi
voxel.obj(voxel)
Error 42: Symbol Undefined _Dtinyptc_ptc_update_FPvZi
--- errorlevel 2

Thanks in advance,
Mac

You should tell linker which libs to link=2E It only links module =2Eobjs

not libraries =28Walter=2C maybe some way for a module to specify which

Each module is a separate =2Eobj file=2E If you want to use it=2C you have to

Any non-standard ones are left up to you=2E

Using my windows.d was always a pain in the... The best idea
is to avoid using it at all, declaring all functions that
it needs yourself. The latest DMD version has much better
windows.d, many functions are already there. I'll try to
make TinyPTC compatible with it.

Yes, but using the with the newest DMD shipped windows.d produces:

"tinyptc.d(264): cannot implicitly convert int to HANDLE"

I would really like to see the voxel engine working...

Perhaps you can send me a tinyptc.obj from you so that I can link
that with the voxel.obj demo?

(Walter, maybe some way for a module to specify which objs/libs


it wants to link with, added into the language?):

In general there ought to be a way to pass implementation defined parameters
to the compiler in the source code, but I haven't worked out the details.
