Re: [FLASH-USERS] a problem when compile FLASH code (mpi_wtime undefined"

You might try to add -lpmpich to your link line. (That is, in your
Makefile.h, add -lpmpich to LFLAGS_{OPT,DEBUG,TEST}.

Reference: http://www-unix.mcs.anl.gov/mpi/mpich/docs/mpichman-chp4.pdf,
bottom of page 56 in the manual (as opposed to the pdf file page number.)
