I am attempting to compile a trivial GLUT program using gcc in cygwin.
(the program is so small and trivial I have included it at the end of this
message)
I am unable to get the program to link.
gcc -c -o gldemo.o gldemo.cc
gcc -o gldemo.exe -lglut32 -lglu32 -lopengl32 gldemo.o
gldemo.o(.text+0x2f):gldemo.cc: undefined reference to `glutInit@8'
gldemo.o(.text+0x3c):gldemo.cc: undefined reference to
`glutInitDisplayMode@4'
there are similar errors for glut function call.
I appreciate any insight into my omission.
8-line gldemo.cc follows:
#include <gl/glut.h>
void main(int argc, char **argv) {
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_DEPTH | GLUT_SINGLE | GLUT_RGBA);
glutInitWindowPosition(100,100);
glutInitWindowSize(320,320);
glutCreateWindow("3D Tech- GLUT Tutorial");
}
