error LNK2001: unresolved external symbol

[garryMarshall]

My code under VS7.0 works under debug mode. But when I change it to Release mode two out of four methods in my class can not link. I have included part of that code.

Any help would be appreciated.

Does the .cpp file have the .h #included? I noticed that the compiler error is showing all the size_t's as unsigned int's. Have you tried changing all the size_t's to unsigned int's to see if it atleast allows the module to compile?

[garryMarshall]

Yes the .cpp does include the .h #include. The code does compile in release mode but does not link. The same code in debug mode compiles, links and runs with no problem. I did change the size_t to int and it still does not link in the releaser version.
Thanks for help, garry

[Andreas Masur]

Well...trying the obvious....did you compare the linker settings for both debug and release?

[garryMarshall]

Yes, I compared all of the settings between the debug and release versions. The only difference is where it has to be different, which isn't very many places.
Thanks, Garry
