this is probably not a problem of the fortran 77 compiler, but
the result of some incompatible library or linker flags. please
check out the config.log file as suggested. if you have trouble
with the atlas library, you may want to check out the libraries
i have put up for download at:
these libraries contain the full BLAS/LAPACK/ATLAS and are built
specially, so that they are compatible to _any_ current fortran
compiler currently avaible for linux. to have the configure script
recognize them, however, you have to emulate a full ATLAS install
via creating symlinks for libf77blas.a, liblapack.a, libcblas.a,
and libatlas.a. e.g. like this
ls -l ~/lib/
lrwxrwxrwx 1 akohlmey theochem 17 Sep 19 16:37 libatlas.a -> libatlas_athlon.a
lrwxrwxrwx 1 akohlmey theochem 10 Jul 1 09:32 libblas.a -> libatlas.a
lrwxrwxrwx 1 akohlmey theochem 10 Jul 1 09:32 libcblas.a -> libatlas.a
lrwxrwxrwx 1 akohlmey theochem 10 Jul 1 09:32 libf77blas.a -> libatlas.a
lrwxrwxrwx 1 akohlmey theochem 10 Jul 1 09:32 liblapack.a -> libatlas.a

espresso needs a usable fortran 90/95 compiler. i doubt that
g95 in anywhere near what is needed. g77 does not understand
fortran 90/95 at all (but it can compile simple free format
fortran programs which is why the configure does not barf).
you can get a personal, unsupported, non-commercial license
for the intel compiler (version 8.1 works nicely) free of charge.
you should then also register for premier support (which is also
free of charge for a year) to get access to updated versions
and an x86_64 (a.k.a. E64MT) version for athlon64/opteron machines.
if you just want to try it out, i do occasionally create
linux binaries for a few colleagus and put them at
feel free to download them, but don't expect me to fix them,
if they don't work for you. they may have some additional changes
that i need, but are not (yet) in the official espresso version.
