Re: [Boost-users] Using MPL to cut array?

The first thing is, that you have to use a constant with external linkage, otherwise you can not pass the string as argument. extern const char* fname = __FILE__; Afeterwards you need to cut the end ;) what is a more difficult task. Read through the MPL algorithms. But another question: If you do it like mentions. You path will become incorrect, if executable is moved, since it will be calculated at compile time.

Hello,

__FILE__ is a macro for the path to the current source file. I would like to remove the common prefix (like "c:\dev\my_program\") from it, which is in a preprocessor macro SOLUTIONDIR. Is there a metaprogramming way to do that?

So the class TSuffix should be used like this:

TSuffix::value // cuts prefix of length n off char array x

It would be nice if the compiler would not even store the whole path in the executable, but only the distinguishing suffix. Any ideas how to start?

TIA,
