Borland C++ Builder compile error

Question

I am using Borland C++ Builder 6, on an XP PC. When I compiled a software unit that made reference to crtdbg file, I received the following error messages:

/* Borland version of Microsoft CRTDBG.H header file
   This is used by MFC and ATL.
*/

/*

 *

[C++ Error] crtdbg.h(52): E2268 Call to undefined function '_T'
[C++ Error] crtdbg.h(52): E2034 Cannot convert 'int' to 'const char *'
[C++ Error] crtdbg.h(52): E2340 Type mismatch in parameter 2 (wanted 'const char *', got 'int')

I have no idea what's wrong with it. Any help would be appreciated.

Thanks in advance, David.

Answer 1

You should add the TCHAR.H include (or a Borland equivalent).

_T() is a macro that converts 8-bit strings into wide character format.
