How do I configure eclipse with Turbo C++ compiler.
Short answer: don't!
Embarcadero Technologies (which acquired all of Borland's compiler tools with the purchase of its CodeGear division in 2008) discontinued the support of Turbo C++ 2006. Why use a tool that was abandoned 6 years ago?
Turbo C++ was succeeded by C++Builder, which has it's own IDE.
If you want to do C++ development in Eclipse you should use Eclipse IDE for C/C++ Developers (~107MB).
