Hello, I have a program that will built both under fedora and under
cygwin. The program is written in C and the Makefile is slightly
different between the two systems. Is it possible to check some
environment variable in the makefile to determine what to do?
The source code itself have constructs like these for parts that differ
between cygwin and fedora:
#if defined __CYGWIN__
/* Turn on vsync, this works on Cygwin. */
SDL_GL_SetAttribute(SDL_GL_SWAP_CONTROL, 1);
#elif defined __linux
/* Fedora doesn't support SDL_GL_SWAP_CONTROL, but we use this
extension instead. */
SDL_putenv("__GL_SYNC_TO_VBLANK=1");
#endif
and I'm looking for something similiar to use with the Makefiles so I
can turn the two Makefiles into one.
I hope this is considered on-topic, if not, I apologise.
