Thanks for that. I hadn't realised GLUT and OpenGL were supported out
of the box like that. I'd done some Googling trying to find
instructions for compiling GLUT programs and nothing I came across
mentioned an OpenGL Cygwin package. Next time I'll read the package
list more carefully!
Anyway I've now got it compiling cleanly, but there's a totally
unrelated runtime error which after investigation looks like it's
caused by sscanf(3) not working properly with "%as". The following
code which works under Linux (sscanf returns 1) but not under Cygwin
(sscanf returns 0) demonstrates the problem:
#include <stdio.h>
int main(int argc, char *argv[]){
char *string = "This is a string\n";
char *word;
if(!sscanf(string, "%as", &word)){
fprintf(stderr, "No string in string.\n");
}
else{
printf("Found `%s' in string.\n", word);
}
return 0;
}
Mark.
