[mvapich-discuss] Problems building MVAPICH2 2.3.4 w/o flex

[Dan Pou]

Resending, because of a mail configuration error.

The 2.3.4 release fails to build if you don't have flex (or suitable lex command) installed.
The build does not flag lex as missing, just errors out with a missing file.
The ylwrap LEX command is just : in a build without flex, it called flex after I installed it.

It looks like the file
mvapich2-2.3.3/src/pm/mpirun/src/hostfile/scanner.c
was shipped in the 2.3.3 release, but not in 2.3.4.

   YACC     src/pm/mpirun/src/hostfile/src_pm_mpirun_src_hostfile_libhostfile_a-parser.c
mvapich2-2.3.4/src/pm/mpirun/src/hostfile/parser.y: warning: 2 shift/reduce conflicts [-Wconflicts-sr]
