Hi,
I've built LAM on OSX10.4 with the GNU compilers and the PBSPro tm boot
mechanism. It worked fine, and I've compiled and run a few of my c++ MPI
codes without a hitch. But now I am trying to build a big application,
petsc-2.3.0, and am having a lot of trouble which I interpret to be link
errors. I wonder if anyone has had success with this or has a comment?
The version details are:
PBSPro version ?
OSX 10.4 (gcc 4.0.1)
PETSc 2.3.0
lam-7.1.1, or
lam-7.1.2b31 (both these versions of lam produce the same errors)
With LAMHOME=/usr/local/lam-7.1.2b31, the offending command and its errors
(from the petsc configure.log file) are appended below. To its credit, the
petsc configurator is doing its very best to find the libraries properly.
Does anybody have any pointers or have a successful build story?
I know your probably all quite busy with SIAM coming up, but any comments or
help would be greatly appreciated,
Thanks,
Sean Dettrick
