Known issues

Some versions of MPICH and SCore provide buggy driver-scripts for the compiler. The scripts parse the command-line and alter it before handing it down to the actual compiler. This may lead to a false assumption about the style of dependency tracking. As a consequence, rebuilds of the source may fail with an error message similar to

  cpp0: you must additionally specify either -M or -M

If this happens, there are several possible work-arounds and fixes:

• in the subdirectories mpi/ and src/ of the build-tree, delete the object files producing the error, that is, the ones corresponding to the source files that were changed, then rebuild with make
• supply the driver-script as the CXX compiler, i.e. use ./configure [YOUROPTIONS] CXX=mpiCC
• disable dependency tracking by using the switch -disable-dependency-tracking when running configure.
• patch the driver scripts mpic++ and mpiCC (when using SCore, they are located in a directory similar to /opt/score/mpi/mpich-1.2.4/i386-redhat7-linux2_4_gnu/bin
