I'm unsing Dev-Cpp 4.9.9.0 with Windows 2000.
When I'm trying to compile an application with GLUT written in C, compiliation of the objects works fine, but I get plenty of linker errors (log and error messages included at the end of this message).
What I have done to solve the issue:
I'm really stuck right now and would appreciate any help.

My friend who helped my told me, he could successfully compile the program using gcc from CygWin, but I don't know the version he used.
Christian
Try changing the order of your libs.
gcc is sensitive to the order in which things are linked. I often have this problem when compiling fltk programs.
LIBS = -L"C:/Dev-Cpp/lib" -lglut32 -lopengl32
Suggestion might be:
LIBS = -lglut32 -lopengl32 -L"C:/Dev-Cpp/lib"

I have already tried some different orderings from the command line, but it didn't help :-(
Christian
Where did you get GLUT from, and what did you do with the components you downloaded? Step by step please. Header files, library files and dll files.
Your linker errors suggest to me that your glut's dll file is not in the right place.

I got GLUT from this source:
http://www.xmission.com/~nate/glut.html
I took the package "glut-3.7.6-bin.zip" and copied:
glut32.dll --> C:\WINNT\System32
glut32.lib --> C:\Dev-Cpp\lib
glut.h --> C:\Dev-Cpp\include\GL
After I read your message, I downloaded GLUT from the OpenGL homepage:
http://www.opengl.org/resources/libraries/glut/glut_downloads.html
I downloaded "glutdlls37beta.zip" and copied:
glut.dll --> C:\WINNT\System32
glut32.dll --> C:\WINNT\System32
glut.lib --> C:\Dev-Cpp\lib
glut32.lib --> C:\Dev-Cpp\lib
glut.h --> C:\Dev-Cpp\include\GL
But this did not help, I still get the same linking errors.
I'm not sure, but even if the DLL was in the wrong place, linking should still be no problem, shouldn't it? I thought the DLL is loaded at runtime, not at link time...?
If you like to test my project yourself, you can get it here:
http://www.dgm.informatik.tu-darmstadt.de/courses/cg1/ex/cg1_ex1.zip
Nevertheless, thanks for your help!
Christian
It looks like the static libraries linked, but the dynamic library was not located - hence my question above.
Wayne
Finally I got it to link with Cygwin's gcc v3.3.3. I installed Cygwin with some additional packages and changed the binary path for Dev-Cpp to C:\Cygwin{usr\,}bin. But then I got compiler errors because of some missing typedefs in file glu.h. So I removed any path from the Dev-Cpp library and include path -- and my program compiled and linked fine.
I don't know what kind of difference there is in both gcc versions, but I guess Cygwin's gcc does not use the static libs in C:\Dev-Cpp\libs. This seems quite strange to me.
Here is the compiler log:
------<snip>-------------------------------------------------------------
rm -f cg1_ex1.o glutcallbacks.o robot.o scenegraph.o uebung1.exe
gcc.exe -c cg1_ex1.c -o cg1_ex1.o

gcc.exe -c robot.c -o robot.o
gcc.exe -c scenegraph.c -o scenegraph.o
gcc.exe cg1_ex1.o glutcallbacks.o robot.o scenegraph.o -o "uebung1.exe" -lopengl32 -lglut32 -lglu32
Ausfhrung beendet
Kompilierung erfolgreich
------</snip>-------------------------------------------------------------
Note that the additional switch -lglu32 is indeed necessary, but I already tried it with the gcc version coming with Dev-Cpp, without success.

Christian
So I guess nobody has a clean solution for that? Where could I get a GLUT version that works with the Dev-Cpp libraries?
Christian
The version I refer to in the "Getting Started" thread works fine for me.
Wayne
Christian,
I have read your post cause I have got the same problem when trying to compile a simpler glut application using Dev-C++. I'm really stuck with this :-( My friends reported the same type of problem. Some of them have even managed to compile their code in Microsoft Visual C++ getting better results.
The problem is that I WANT to compile my code in Dev-C++! It's a good compiler and I'm too lazy to change my programmer habits so often ^_^
Sorry...

You might want to try OpenGLUT (http://openglut.sf.net) which has a DevPak on their SF download page, although I've never tried it.
The Nate Robins port of the Mark Kilgard GLUT is not actively maintained, so is probably no longer the best.
I'll give it a go later when I get my copy of Dev working again.
Cheers,
Ian
