Include header path change from Windows to Linux

Question

I\'m porting an application written in C++ from Windows to Linux. I have a problem with the header files path. Windows uses \\ and Linux uses /. I

You people! Yes, you can, and should, always use forward slashes. I think the issue is how to get there from here!

If you have Perl installed, the following one liner will convert a C++ source file to use forward slashes, saving the original version in a file with extension .bak:

perl -i.bak -pe "tr!\\!/! if /^\s*#\s*include\b/" myfile.cpp

(The above command line is for Windows; if you're using Linux or other Unix-like shell, use single quotes around the 3rd parameter instead of double quotes.)

If you have a bunch of files you need to convert, say all files ending in .cpp:

for %f in (*.cpp) do perl -i.bak -pe "tr!\\!/! if /^\s*#\s*include\b/" %f

The corresponding command for a Bourne shell environment (typical Linux shell):

for f in *.cpp; do perl -i.bak -pe 'tr!\\!/! if /^\s*#\s*include\b/' $f; done

If you don't have Perl installed, you should be able to find a text editor that allows search and replace across files.
