Problems compiling example scalapack application

Question

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?

How to Run Example Program Using MPI

Answer 1

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
