[petsc-users] libpetsc.so: undefined reference to `_gfortran_transfer_character_write at GFORTRAN_1.4'

[Satish Balay]

detailed logs would have been useful.

Mostlikely you have multiple version of libgfortran.so - and the wrong
version got linked in.

Or you have blas [or something else] compiled with a different version
gfortran so its attempting to link with a different libgfortran.so]

You can look at the link command, and look at all the .so files in the
linkcommand - and do 'ldd libblas.so' etc on all the .so files in the
link command to indentify the differences.

And after you locate the multiple libgfortran.so files [perhaps with
'locate libgfortran.so'] - you can do the following to indentify the
libgfortran library that you should be using.

'nm -Ao libgfortran.so |grep _gfortran_transfer_character_write at GFORTRAN_1.4'

Or use --with-shared-libraries=0 and see if this problem goes away..
