I\'m looking to compile some old source code in Visual C++. However, the first of many errors I am receiving is:
vcl.h: No such file or directory
This old code must have come from C++Builder. If it actually uses the VCL, you won't be able to build it with any other compiler. If there are other VCL includes like classes.hpp, system.hpp, controls.hpp, etc. it is using the VCL.
If it is a console application and doesn't actually use any VCL classes, then you can probably just remove the include, but the chances are slim.
