Undefined references using GLUT with MinGW
At the top of the source file mycube.c you have to include
#include<windows.h>or include
#include<GL/gl.h> or #include<GL/glu.h>Then compile you code there will be no such type of error.
The glut library you downloaded was built for 32-bit programs. It looks like your MinGW is building for a 64-bit target, which uses different names than the 32-bit (and is incompatible anyway).
Try adding the -m32 option to get MinGW to builds a 32-bit program:
gcc -m32 -Wall -ofoo mycube.c -L"C:\MinGW\lib" -lglut32cu -lglu32 -lopengl32Note that mt 64-bit MinGW compiler (gcc version 4.6.1 (tdm64-1) from http://tdm-gcc.tdragon.net/download) gives a small clue about this problem:
ld.exe: skipping incompatible .\glut32\lib/libglut32cu.a when searching for -lglut32culd.exe: cannot find -lglut32cu
