gcc/g++ option to place all object files into separate directory

Question

I am wondering why gcc/g++ doesn\'t have an option to place the generated object files into a specified directory.

For example:

mkdir builddir
mkdir          


        

Answer 1

A trivial but effective workaround is to add the following right after the gcc call in your Makefile:

mv *.o ../builddir/objdir

or even a soft-clean (possibly recursive) after the compilation is done, like

rm -f *.o

or

find . -name \*.o -exec rm {} \;
