How can I resolve linker issues when I compile this C++ program that requires GLUT?

Question

I'm trying to compile this C++ program which utilizes the GLUT32 libraries.

Right now I'm getting the following errors:

Error 1 error LNK2001: unresolved external symbol _gluPerspective@32 Camera.obj soundCube Error 2 error LNK2001: unresolved external symbol _gluLookAt@72 Camera.obj soundCube Error 3 error LNK2001: unresolved external symbol _imp_glMaterialfv@12 GLWindow.obj soundCube Error 4 error LNK2001: unresolved external symbol _imp_glClear@4 GLWindow.obj soundCube Error 5 error LNK2001: unresolved external symbol _imp_glClearColor@16 GLWindow.obj soundCube Error 6 error LNK2001: unresolved external symbol _imp_glMaterialf@12 GLWindow.obj soundCube Error 7 error LNK2001: unresolved external symbol _imp_glEnd@0 GLWindow.obj soundCube Error 8 error LNK2001: unresolved external symbol _imp_glRasterPos2f@8 GLWindow.obj soundCube Error 9 error LNK2001: unresolved external symbol _imp_timeGetTime@0 GLWindow.obj soundCube Error 10 error LNK2001: unresolved external symbol _imp_glDisable@4 GLWindow.obj soundCube Error 11 error LNK2001: unresolved external symbol _imp_glBegin@4 GLWindow.obj soundCube Error 12 error LNK2001: unresolved external symbol _imp_glColor4f@16 GLWindow.obj soundCube Error 13 error LNK2001: unresolved external symbol _imp_glPopMatrix@0 GLWindow.obj soundCube Error 14 error LNK2001: unresolved external symbol _imp_glPushMatrix@0 GLWindow.obj soundCube Error 15 error LNK2001: unresolved external symbol _imp_glRotatef@16 GLWindow.obj soundCube Error 16 error LNK2001: unresolved external symbol _imp_glBlendFunc@8

...

Error 56 fatal error LNK1120: 55 unresolved externals C:\Users\Simucal\Documents\Downloads\SoundCubeSrc soundCube

I'm not that experienced in C++ but I've tried to set up GLUT correctly so this project can link against it.

I downloaded the GLUT32 library for Nate Robin's page.

I then placed the following files in:

• glut.h - C:\Program Files\Microsoft SDKs\Windows\v6.0A\Include\gl
• glut32.lib - C:\Program Files\Microsoft SDKs\Windows\v6.0A\Lib
• glut.dll - C:\Windows\System32

I also selected the Project -> Properties -> Linker -> Additional Dependencies -> Added "glut32.lib"

If anyone wants to see what project I'm working with, it is here.

What step am I missing or doing wrong in order to resolve these errors?

Answer 1

it looks to me like you're mixing static and dynamic link options. I'm downloading your project to investigate, but what type of compilation are you doing?

I didn't see a reference to the glut .lib file in the project...

I added the library reference and LIB/INCLUDE paths:

Answer 2

The unresolved symbols are from the GL and GLU libraries. You need to add the link libraries for them as well.
