This looks like LAM 7.0, correct? Unfortunately, there is a bug in the
configure script for LAM 7.0 with regards to threading. The configure
script incorrectly assumes that threading flags that work for the C
compiler will work with the Fortran compiler. There are a couple of
ways around the bug that should work for you.
* If you use the argument --without-dash-pthread to configure, LAM will
use the
standard -lpthread rather than the compiler option -pthread. This
won't work on the
BSDs, but should work fine on most Linux distros (possibly not RH
9.0).
* You can disable thread support entirely with the --without-threads
argument to
configure. LAM will work fine, it just will not support MPI
threading levels above
MPI_THREAD_SINGLE
We plan on releasing LAM 7.0.1 real soon now, which will include a much
improved threading test (as well as a couple other bug fixes).
Hope this helps,
Brian
