What should I do in order to succesfully link a C++ Builder 6 project in C++ Builder 2009 without unresolved external references to CodeGuard things?

Question

Here's what I did:

1. I've opened a C++ Builder 6 - project in C++ Builder 2009.
2. Auto-converted it to a C++ Builder 2009 project.
3. Told it (C++ Builder 2009) to build everything.

Here's what it did:

1. Successfully compiled everything.

2. Failed to complete ILINK32, exiting with

   "Error: Unresolved external '_CG_DESC' referenced from MyProjectsFirstFile.obj".
   

Answer 1

It looks like a Code Guard error. Try deleting all the object (.obj) files and rebuilding the entire project.

If this still does not work, then turn off the Code Guard option in C++Builder 6 and try importing the project again.

Never let the IDE auto-upgrade a project from an old version. It never works correctly. Instead, always create a new project fresh and add your existing source files to it as needed.
