Subject: Re: [OMPI devel] make install (libtool) failure on Solaris 10 (1.5rc5 and 1.4.3rc1)
From: Paul H. Hargrove (PHHargrove_at_[hidden])
Date: 2010-08-26 14:23:36


I agree w/ Ralph that
    ln -s -f A B || { rm -f B && ln -s A B; }
should have worked despite the error message from the failing "ln -s -f
A B".
So, I don't think there was a real error here - sorry.
