Hi,

from the error log you have two problems:

- the pgi compiler binaries are not in your user's path. Assuming you are
using the BASH shell you should edit the
.bash_profile file in your home directory and add the following two lines

export PATH= "path to pgi binaries":$PATH
export LD_LIBRARY_PATH = "path to pgi libraries":$LD_LIBRARY_PATH

You will need to find the actual path on your system, by typing for example:

locate pgf90

it should be something like:

/opt/pgi/linux86-64/7.2-5/bin/ (for binaries)

and

/opt/pgi/linux86-64/7.2-5/lib/ (for libraries)
+
/opt/pgi/linux86-64/7.2-5/libso/


- you've hit a known bug in the RegCM configure script, to compile RegCM
with the PGI compiler in parallel you should edit the Makefile.inc file and
remove the leading # from the line :

#PARALLEL = MPP1

By the way PGI 7 compilers are not officially supported by RegCM. Compiling
should work, but the program was not tested with it. If you can upgrade your
PGI compiler or switch to GNU Gfortran 4.4 which is fully supported.

Hope I've been useful

Martin
