Re: Building GFortran on Cygwin

It is almost an year that I build GFortran on Cygwin using the source gcc-svn.tar.bz2, configuring as

and


    make
    make install


I have tried a new build with the current 20060930 gcc-svn.tar.bz2 but it fails in this way:

Any idea of this fail ?

I did the last useful build with the source gcc-svn.tar.bz2 Sep 03, 2006.


Cheers,


Angelo.


Angelo,

Make sure you have all the build tools. See http://gcc.gnu.org/install/prerequisites.html

Also, make sure your build directory is a completely different directory from the sources tree.
