Hi Cathryn,

This says that your pgf90 compiler failed the Fortran test program.
In order to figure out exactly what happened, we will need to see
the contents of 'config.log'.

Right.  Since your ptf90 compiler failed the 'configure' test program,
the Makefile was created to not build the Fortran interface.

>So now why can it not find my Fortran-90 compiler?

It found the compiler, but the compiler failed the compilation test.
Again, we need to see the contents of 'config.log' in order to determine
why the test was failed.

You specified it as a non-Fortran-90 compiler by defining the environment
variable FC:

setenv CC /usr/bin/gcc
setenv CPPFLAGS "-DNDEBUG -DpgiFortran"
setenv CPFLAGS -O
setenv FC /usr/pgi/linux86/bin/pgf90
setenv FFLAGS "-O"
setenv CXX /usr/bin/g++

If pgf90 can only be used as a Fortran-90 compiler, you would want to
specify the F90 environment variable, not FC:

setenv CC /usr/bin/gcc
setenv CPPFLAGS "-DNDEBUG -DpgiFortran"
setenv CPFLAGS -O
setenv FC ""
setenv F90 /usr/pgi/linux86/bin/pgf90
setenv FFLAGS "-O"
setenv CXX /usr/bin/g++

>Thanks,

No worries.

Cheers,

Tom
