Re: a small question about subst

You haven't given us nearly enough information to help you.  What
version of GNU make are you using?  What does "fail" mean (what actually
happens?)  How are you using this, exactly?  Please provide a small
_real_ makefile example where it fails.

As far as I can tell, subst does exactly what is expected:

    $ echo 'all: ; @echo $(subst folder1/,,/root/folder1/file1)' | make -f-
    /root/file1
