So I have been trying to build multiple applications with an ifort+gcc implementation of Open-MPI. I wanted to build them in debug mode. This is on a Macbook Pro System Version: Mac OS X 10.4.9 (8P2137) Kernel Version: Darwin 8.9.1 gcc :gcc version 4.0.1 ifort: 10.0.16
I have tried building PETSc from ftp://ftp.mcs.anl.gov/pub/petsc/release-snapshots/petsc-lite-2.3.3-p1.tar.gz in debug mode and the error on gets in building fortran examples is: *ld*: *internal error*: *output_local_symbols*() inconsistent local symbol count This does not happen when *not* in debug mode. This is the same error we get with the same build parameters of one of our Fortran scientific codes. This error does *not* occur when using mpich2-1.0.5p4.
