Argh. Someone somewher has done "#define sleep Sleep" and it's messing over
the definition of sleep() in unistd.h making it conflict with Sleep() from
winbase.h. No, hang on, it's even worserer than that:
# 69 "/usr/include/X11/Xwindows.h" 3 4
#define sleep(x) Sleep((x) * 1000)
... leading to this nonsensical declaration:
unsigned __attribute__((__cdecl__)) Sleep((unsigned int __seconds) * 1000);
Ok, so you can work around that with careful ordering, as long as you don't
want the unistd version of sleep. Try it like this:
ad...@ubik /tmp/x
$ cat test-x.c
#include <stdio.h>
#include <unistd.h>
#include <X11/Xwindows.h>
#include <windows.h>
int main() {
printf("Hello\n");
return 0;
}
ad...@ubik /tmp/x
$ gcc-4 test-x.c -Wall -lX11 -lcomdlg32 -o test-x.exe --save-temps
ad...@ubik /tmp/x
$ ./test-x.exe
Hello
ad...@ubik /tmp/x
$
cheers,
