I got libMesh to compile. At first I thought it was because of the
autoconf option - but I just tried again without it (to try to recreate the
problem) and it worked again!
I've been in contact with the admins so I suspect they fixed something on
their side.
At the places it used to die I now get these messages:
libtool: link: warning:
`/bgsys/drivers/toolchain/V1R2M0/gnu-linux/powerpc64-bgq-linux/lib/
libgfortran.la' seems to be moved
libtool: link: warning:
`/bgsys/drivers/toolchain/V1R2M0/gnu-linux/powerpc64-bgq-linux/lib/libstdc++.la'
seems to be moved
I don't know why it wasn't able to detect that earlier... or what they
might have changed - but.... IT WORKS!
Thanks everyone for your help - I REALLY appreciate it!
