<html><div style='background-color:'><DIV class=RTE> <P><BR>Ok, I just tested the package. I thought it was similiar to glut, and thats how I solved my linker errors (include windows.h).

Hurray! Matching the linker settings to those in the template resolv= ed=20 the linker errors. Thanks for your help Damien and Bal=E1zs. Damien A wrote: > > Ok, I just tested the package.

The linker spitted this (what you posted): g++.exe src/cobject.o src/cstring.o src/main.o src/cmemorystream.o src/capplication.o src/cwindow.o -o "Core.exe" -L"C:/Dev-Cpp/lib" -lopengl32 -lfreeglut src/capplication.o(.text+0xc):capplication.cpp: undefined reference to `_imp__glutInitDisplayMode@4' src/capplication.o(.text+0x1e):capplication.cpp: undefined reference to `_imp__glutIdleFunc@4' src/capplication.o(.text+0xb8):capplication.cpp: undefined reference to `_imp__glutDisplayFunc@4' src/capplication.o(.text+0xca):capplication.cpp: undefined reference to `_imp__glutReshapeFunc@4' src/capplication.o(.text+0xdc):capplication.cpp: undefined reference to `_imp__glutMouseFunc@4' As you see, the linker cannot find symbols like "_imp__glutMouseFunc@4" etc. However, you might wonder why, as glutMouseFunc IS defined in the freeglut headers. But if you take a closer look, it is prefixed with "_imp_" which marks, that the linker is looking for an imported function, that is: a function, which is inside a DLL. And this happens because the compiler compiled your program without the define I wrote (-DFREEGLUT_STATIC), and by default, the headers of freeglut set up things to use the dynamic build of freeglut (FREEGLUT_DYNAMIC is the default). So when you linked your program, the linker looked for imported functions, however the freeglut devpak contains a static build, and a static library's functions don't contain "_imp_" decorations. The linker saw the two as totally different symbols. I hope that helps a bit to see the works in behind. -- Greetings, Balázs |

Unfortunately, that didn't help. My application compiles without error, it's some kind of linking problem. I'm using freeglut 2.2.0 from http://freeglut.sourceforge.net/.
