Question

Environment: I am using MS-VC++ 6.0,

• I include a group of header file with
  some data.
• The header files change often, so on
  every change I change the path
  setting and re-compiler
• A log file is generated based on the
  included header files

• For tracking of the header file from
  the log file, I wish to print the
  header file path inside the log

• Question-1: Is getting the header
  file path from inside the program
  possible?

• Question-2: I am using VC++, but if
  it is possible in gcc, then I can
  easily port, so, please let me know,
  if it is possible in any other
  environment like gcc

Answer 1

In VC++, compiling with the option /FC will put the currently processed file’s entire path in the __FILE__ macro.

That will account for your changes to the include path.
