[Beowulf] Problem using PGI compiler to link BLACS with mpich

[Ivan Paganini]

Hello everybody at Beowulf: this is a rather silly question, but it
giving me a long lasting headache, so maybe someone here can help me. I
am trying to compile my scalapack application without using the ACML
3.1.0, that has some bugs and problems with compilers, besides some
other problems. So, I am trying to compile from source my libraries.
mpich 1.2.7 compiles with no problem with
+++++++++++++++
env CFLAGS="-fast" CXXFLAGS="-fast" FFLAGS="-fast" F90FLAGS="-fast"
LDFLAGS="-fast" \
OPTFLAGS="-fast" CC="pgcc" CXX="pgCC" F90="pgf90" FC="pgf77"
CPP="pgCC -E"
+++++++++++++++
from PGI guide, and
++++++++++++
/configure --enable-f77 --enable-f90 --prefix=/usr/local/mpich-1.2.7
--enable-g --enable-debug --enable-dlast -rsh=ssh
++++++++++++
to configure. The tests ran ok. Then I try to compile BLACS from source
with the attached Bmake.inc, and when I try to run the BLACS tests, I
got this:
++++++++++++
root at monge:/usr/local/BLACS-pgi/TESTING# make
pgf77 -o /usr/local/BLACS-pgi/TESTING/EXE/xFbtest_MPI-LINUX-0

:btprim_MPI.f:(.text+0x38c): undefined reference to `mpi_init_'
+++++++++++
what is clearly a name mangling problem, but I was not able to solve
it.
So I am not sure that the libraries are compiled correctly or are
working, and I will not dare to go further to compiling scalapack
without checking that BLACS is ok.

Any ideas?

Thank you very much!
