I have coppied the following code from a book:
#include <gl/glut.h>
int 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”);
}
It compiles nicely but when I try to link it I get the following errors:
C:\MinGW\bin>g++ -o test test.o
test.o(.text+0x15):test.cpp: undefined reference to __glutInitWithExit@12' test.o(.text+0x32):test.cpp: undefined reference to__glutCreateWindowWithExit@
8’
test.o(.text+0x50):test.cpp: undefined reference to `__glutCreateMenuWithExit@8’
test.o(.text+0xa8):test.cpp: undefined reference to glutInitDisplayMode@4' test.o(.text+0xb7):test.cpp: undefined reference toglutInitWindowPosition@8’
test.o(.text+0xcc):test.cpp: undefined reference to `glutInitWindowSize@8’
What am I doing wrong?
- can it have something to do with me not having the .dll files: opengl32 and gl32? (I have the glut32.dll)
- and if so where do I get them.
thanks
Try downloading the windows GLUT lib’s .h, and dll files from here:

Do you have the “glut32.lib” file included in your linker settings?
The glut32.dll is only called when the program is run.
Do your have the library file that if compatiable with your compiler, the one from nates site is for MSVC++ only. Unless your compiler reads MSVC library files, you will need to convert or find one for your compiler.

- I know - strangly enough…

- I havn’t converted anything - how do I do that? - I’m using the minGW compiler.

If you had downloaded the files from nate robins site you should have also got a file called glut32.lib, which should be put in the /lib/ directory in your compilers directory.
Then you will have to add the glut32.lib to your linker settings if you have not done so already.
The glut32.dll is only needed when the program is run, not during the compiling of the program.
I can not tell you anything about the mingw, other then a lot of people have problems.
Maybe better you try the free compiler I use… lcc-win32, nice GUI interface, and I have no problems making GLUT programs.
Just do a google search for lcc-win32…
