SDL native on win32 (minor fixes)

SDL Development
1

I have attached a patch that allows 0.11.3 (cvs) to configure and build
correctly in the test directory for mingw32:

Fixes to src/main/win32/SDL_main.c:

  • added a #if check to _MSVER for mingw32, because mingw32 also requires a
    main() function (or else you’ll get an ‘Undefined Reference to
    WinMain at 16’)
  • I don’t know which one is wrong, but SDL_event (I think) defines
    _SDL_RegisterApp() (which is also in the exports) but SDL_main.c
    declares SDL_RegisterApp(). Added an underscore to all relevant calls.

Fixes to test/configure:

  • The check for the SDL version would break because main was declared as
    main() and not main(int argc, char *argv[]). Fixed this in two spots.

Hack to sdl-config.in:

  • I hardcoded mingw32-specific libraries to the --libs parameter. Because
    of my unfamiliarity with autoconf’ing, I know of no other way to fix
    this (adding ‘-lSDL -lgdi32 -lwinmm’ to SDL_LIBS in configure.in doesn’t
    work because -lSDL is stripped somewhere)
  • This hack exists only to allow 0.11.3 to build under mingw32. From
    reading previous e-mails, it looks like Sam is going to address this in
    one form or another (that is, needing -lgdi32 -lwinmm for sdl-config).

Again, the process that I use to build SDL under mingw32 (assuming you
have i386-mingw32-gcc.exe in your PATH):

Top-level build:
CC=i386-mingw32-gcc configure --target=i386-mingw32 --prefix=/usr/local
–disable-directx -v

I use ‘–disable-directx’ because I’m dev’ing under NT. After configure,
I use:

CC=i386-mingw32-gcc make all install

Test programs:
CC=i386-mingw32-gcc configure --target=i386-mingw32 -v

Then:

make

As far as SDL-demos, I had to copy the patched test/configure over founts
in order for founts to compile. The only other SDL-based program I’ve
tried (other than test/) was LK which worked.

A few concerns:

  • I assume the dll process for mingw32 is broken for now? I’ve tried
    ’–disable-static’ || ‘–enable-shared’ to no avail.

  • I added CheckNASM to mingw32 in configure.in only to find that nasm
    freaks out when called from the ‘strip -fPIC’ script. If I manually
    invoke it from the command line, it works fine.

As I become more familiar with the autoconf system, maybe I can help
address these issues.

Oh yeah, updated VisualC stuff is forthcoming.
