[vsipl++] configure fails to recognize mpich

[Joseph E. Sacco, Ph.D.]

Stefan,

I can confirm that your patch works:

[patch applied to configure]

                          ...
        with mpi enabled:                        yes
        With parallel service:                   mpich
                              ...
        
There are many ways to resolve this issue. mpich1 supports command line
arguments:

$ mpicxx -compile-info
g++ -DUSE_STDARG -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_UNISTD_H=1
-DHAVE_STDARG_H=1 -DUSE_STDARG=1 -DMALLOC_RET_VOID=1 -DHAVE_MPI_CPP
-I/opt/mpich/include/mpi2c++ -fexceptions -c -I/opt/mpich/include

$ mpicxx -link-info
g++ -DUSE_STDARG -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_UNISTD_H=1
-DHAVE_STDARG_H=1 -DUSE_STDARG=1 -DMALLOC_RET_VOID=1 -L/opt/mpich/lib
-lpmpich++ -lmpich -lpthread -lrt


Maybe it would be cleaner to use these directly rather than using
"-show". 

Be well,

-Joseph
