I'm trying to build D2X-XL in Visual C++ 7. I have four goals, to build the projects d2x and d2xgl, using both the Debug and Release configs. In each goal, I'm having a problem.

d2xgl, Debug
Everything compiles. But when it links, I get this error:

Code: Select all

MSVCRTD.lib(crtexew.obj) : error LNK2019: unresolved external symbol _WinMain@16 referenced in function _WinMainCRTStartup

I've also noticed that if I define the entry point as a function that exists in inferno.c, such as MainLoop, it will finish linking, but the *correct* entry point function seems to be

Code: Select all

int _CDECL_ main (int argc, char *argv[])

which is also located in inferno.c. But I have no idea what I need to type in as the entry point to use this.
My linker command line parameters look like this:

Code: Select all

d2xgl, Release
Everything compiles, I get these linking errors:

d2x, Debug
I get a *ton* of compile errors. The first few look like this:

d2x, Release
I *think* the compile errors I get are the same as the ones I get in the Debug config.

Thanks in advance for help in solving any of these problems.

There's no WinMain in any of the sources?

Posted: **Fri Aug 04, 2006 10:11 pm**

I've done a findstr /S /I /C:\"winmain\" *.c on the directory, and found nothing.

Tell you what, I'm gonna move this to the D2X-XL forum, Diedel will more likely see it there.

You need to also grab and use the SDL and SDL_mixer source from my Descent site. Their source zips contain other zips which in turn contain working MSVC 6 and .NET 2003 projects (at least I hope they work now).

You cannot compile D2X-XL with the standard SDL source because I have applied _cdecl to a few global function declarations to allow for compiling the rest with register calling convention enabled.

The project files also contain all required global defines.

I've done that already. I didn't have any trouble building either of those. My \"Solution\" contains 11 projects:

d2x
d2xgl
libmve
mikmod
native_midi
playmus
playwave
SDL
SDL_mixer
SDLmain
timidity

All but d2x and d2xgl will build.

What is MSVC 7? Is that .NET 2003 or 2005? The proper .NET project is D2X-W32.

>>What is MSVC 7? Is that .NET 2003 or 2005?
2003. I *think* that 2005 is VC8.

>>The proper .NET project is D2X-W32
I don't see any project file called that, just an icon file. There's also a folder called d2x-w32, but there aren't any files in it, just a bunch of empty folders. I've redownloaded the source to double-check. I was using d2x.dsw (VC6), which was converted into d2x.sln (VC7).

Update:
As of version 1.6.131, Debug now builds. But trying to build Release gives me this error:

Code: Select all

d:\\cppproj\\d2x\\arch\\sdl\\digi.c(548) : fatal error C1001: INTERNAL COMPILER ERROR  (compiler file 'f:\\vs70builds\\9466\\vc\\Compiler\\Utc\\src\\P2\\main.c', line 146)

I have no idea what this error means or where the directory \"f:\\vs70builds\\9466\\vc\\Compiler\\Utc\\src\\P2\" comes from. I do have a hard drive with the drive letter F, but there is no folder in it called \"vs70builds.\"

Can someone help me build D2X-XL from source?
