Unresolved External Symbols

[Brian_A_]

I am compiling in 64bit mode. Works fine in 32bit.

relapo.lib(guinstruct.o) : error LNK2019: unresolved external symbol gluOrtho2D referenced in function DISPLAYW2

relapo.lib(displaytp.o) : error LNK2001: unresolved external symbol gluOrtho2D

relapo.lib(displayw3.o) : error LNK2001: unresolved external symbol gluOrtho2D

relapo.lib(display04.o) : error LNK2019: unresolved external symbol gluProject referenced in function DISPLAY04

relapo.lib(display00.o) : error LNK2001: unresolved external symbol gluProject

bin\\relap5.exe : fatal error LNK1120: 2 unresolved externals

I am using the 64bit f90 graphics files for opengl.

Are you linking against the 64-bit OpenGL libraries? Please show the buildlog.htm (attach it.) You might be linking to the 32-bit libraries.

I have attached the look file.

[Steven_L_Intel1]

This doesn't tell me what kind of library f90glu.lib is. Can you zip and attach that?

[Brian_A_]

I have attached the f90glu.lib.

Ok - the symbols you're missing come from glu32.lib in the Windows SDK. On my system this is in:

C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Lib\x64

Make sure that this folder is in your LIB path and that glu32.lib is referenced in your link. Compare to the 32-bit configuration to see what is different.
