Borland C++ Builder Tip:
If you are getting a linker error when compiling, and everything makes sense, try this.
Recently I was compiling after adding a new unit. I was package exporting the unit
i.e.
class PACKAGE TMyClass;
and when I would remove the package export, it would link up just fine.
The problem turned out to be a missing #pragma directive in the unit.
The exact line I needed is:
#pragma package(smart_init)
