Public bug reported:
Binary package hint: lam4-dev
It appears that the current LAM development package was configured in an
environment in which the fortran compiler is called "g77". However, an
up-to-date install of the GNU compilers (4.1) yields a system in which
the fortran compiler is called "gfortran". Running "mpiff77" results
in a message that there is no g77 compiler.
To get the "mpif77" command to work, it thus seems necessary to mix 3.x
and 4.1 GNU compilers, or backtrack them all to 3.x. A semi-workaround
is to put a symbolic link to gfortran called "g77" somewhere in the
execution path. If one does that, then mpif77 is able to compile, but
cannot link -- the linker cannot find any mpi routines.
Looking at the LAM website, it appears that the problem could be fixed
by configuring and compiling LAM in an environment where gfortran is the
only fortran compiler. Perhaps there should be different LAM packages
depending on whether the system has the GNU 4.1 or 3.x compilers.
