Re: -mno-cygwin and SDL

When I removed the -I /usr/include it seemed to compile fine (the test1.C is just a skeleton so I'll have to test more later).  Thanks for the help,

I just had this discussion this morning on cygwin-apps.

You can't add -I/usr/include when using -mno-cygwin.  -mno-cygwin causes
the MinGW header files to be used and not Cygwin's "on purpose". 
Circumventing that will cause you to fail.  MinGW only supports ANSI C
as MS sees it with a few "add-ons".  DON'T -I/usr/include WHEN USING
-mno-cygwin.

Earnie.

I tried your suggestion, but I get the same error.  I also looked at the FAQ, it did not give me any clues either.

I modified my compile commands as per the SDL FAQ so that they it is now:

gcc test1.C -mno-cygwin -I /usr/include -o exec/test1.exe -lglut32 -lglu32 -lopengl32 `sdl-config --cflags --libs`

However, now I get the errors:

In file included from /usr/include/SDL/SDL_rwops.h:35,
                 from /usr/include/SDL/SDL.h:37,
                 from test1.C:19:
/usr/include/stdio.h:157: type specifier omitted for parameter
/usr/include/stdio.h:158: type sepcifier omitted for parameter
..

and so on for lines 159, 189, 194-197, 246-252.

Any ideas?

The line above should be changed like this:
gcc test1.C -mno-cygwin -I /usr/include -o exec/test1.exe -lglut32
-lglu32 -lopengl32 -lSDL

Read the FAQ on cygwin.com it contains a topic on WinMain@16.

-mno-cygwin and SDL

[CaetSith7]

Hi, I downloaded and compiled SDL-1.2.3 from source in cygwin, and suprisingly I got it to work.  Then I tried to set -mno-cygwin so that the app would work outside of Cygwin, but I get:

$ make win
gcc test1.C -mno-cygwin -I /usr/include -lglut32 -lglu32 -lopengl32 -lSDL -o exec/test1.exe
/usr/lib/mingw/libmingw32.a(main.o).text+0x8d):main.c: undefined reference to 'WinMain@16'
collect2: ld returned 1 exit status
make: *** [win] Error 1

Does anybody know what's wrong?  Please CC to me since I'm off list.

Thanks,
Shawn Lindberg
