[petsc-users] SCALAPACK compilation error

[Norihiro Watanabe]

Hi,

I'm trying to compile PETSc v3.5.2 with "--download-scalapack". The
full command is

./configure PETSC_ARCH=gcc-release --download-f2cblaslapack=1
-with-debugging=0 --download-superlu_dist --download-hypre=1
--download-ml=1 --download-parmetis --download-metis --download-mumps
--download-suitesparse --download-scalapack --with-fc=mpif90
--with-cc=mpicc --with-cxx=mpicxx

Unfortunately it fails because linking to gfortran library is missing
(see partial log below). Do you have any idea how to fix it? I found
"-lgfortran" is used in several other places in configure.log but not
for the below particular compilation. conf/scalapack also doesn't have
"-lgfortran".
