c++ - Is there a way to automatically have a #define reproduced in each source file

Question

I'd like the following to appear in every source file in my Visual C++ 2005 solution:

  #define DEBUG_NEW new(_NORMAL_BLOCK, __FILE__, __LINE__)
  #define new DEBUG_NEW

Is there a way of doing this without manually copying it in? Compiler option?

Answer 1

The command line option /D can be used to define preprocessor symbols. I don't know, though, whether it can also be used to define macros with arguments, but it should be an easy matter to test that.

Edit: Failing that, the /FI option ("force include") should allow you to do what you want. Quoting the MSDN documentation:

This option has the same effect as specifying the file with double quotation marks in an #include directive on the first line of every source file [...] .

You can then put your #defines in that forced include file.
