5 glew.c compilation on CYGWIN - ID: 1839667

Last Update: Comment added ( sf-robot )

Details:

Hi,

I am building glew.c within my own build system. For some reason, WINAPI
does not get defined on CYGWIN, since the inclusion of windows.h is disable
in wglew.h. My command line is:

cc -I.././build/CYGWIN_NT_5_1/include -DWIN32 -D_WIN32 -DCYGWIN_NT_5_1
-DWGL -DEQ_CHECK_THREADSAFETY -DEQ_USE_COMPRESSION -DGLEW_MX -DNDEBUG
-DWIN32 -D_WIN32 -DWIN32 -D_WIN32 -DSUBDIR=\"./lib\" -MMD -MF
.././obj/./lib/glew/glew.CYGWIN_NT_5_1.i686.o.d -c glew/glew.c -o
.././obj/./lib/glew/glew.CYGWIN_NT_5_1.i686.o

In file included from glew/glew.c:34:
.././build/CYGWIN_NT_5_1/include/GL/wglew.h:89: error: parse error before
'*' token
.././build/CYGWIN_NT_5_1/include/GL/wglew.h:89: error: parse error before
"hDC"
.././build/CYGWIN_NT_5_1/include/GL/wglew.h:89: error: `BOOL' declared as
function returning a function
...

Environment is Cygwin, GLEW 1.4.0.

Any ideas what's going wrong?

Cheers,

Stefan.

You need to include glxew.h instead and run the application under Cygwin's X server. If you want to build a Windows application using Cygwin's gcc, I recommend using the -mno-cygwin option, which builds your program as a MinGW application. To build GLEW for MinGW using Cygwin's gcc, type: make SYSTEM=cygming See also http://www.delorie.com/howto/cygwin/mno-cygwin-howto.html I hope this helps, - Milan
