Problems compiling example scalapack application

When I do:

mpif77 example1.f -L scalapack/scalapack-1.8.0/ -lscalapack -L scalapack/blacs/BLACS/LIB -l:blacsF77init_MPI-LINUX-0.a -l:blacs_MPI-LINUX-0.a -l:blacsF77init_MPI-LINUX-0.a -L scalapack/blas/BLAS/ -l:blas_LINUX.a  -L scalapack/lapack/ -llapack -L/cm/shared/apps/gcc/4.4.6/lib64/ -lgfortran

I get:

scalapack//blas_LINUX.a(xerbla.o): In function `xerbla_':
xerbla.f:(.text+0x66): undefined reference to `_gfortran_transfer_character_write'
xerbla.f:(.text+0x76): undefined reference to `_gfortran_transfer_integer_write'
collect2: ld returned 1 exit status

Could it be something with the order in which the libraries are linked?

It linking error. These dependences usually come when using different fortran compilers for libraries and executables (f77, f90). Try to use mpif90 to compile your example.

You can test using :

$ mpif77 --showme
gfortran -I/usr/lib/openmpi/include -pthread -L/usr/lib -L/usr/lib/openmpi/lib -lmpi_f77 -lmpi -ldl -lhwloc
$ mpif90 --showme
gfortran -I/usr/lib/openmpi/include -pthread -L/usr/lib -L/usr/lib/openmpi/lib -lmpi_f90 -lmpi_f77 -lmpi -ldl -lhwloc

The only difference is -lmpi_f90
