[mpich-discuss] Hard-coded path to mpiexec.hydra.conf (1.4, 1.5)

[Yauheni Zelenko]

Hi, Pavan!

Thank you for help!

However will be good idea to disable check of file in install location at all.

Or there should be way to specify install location in run-time with environment variable or command-line option (OpenMPI uses OPAL_PREFIX and --prefix correspondingly).

Other files affected are mpi compilation scripts (mpicc, etc), MPE scripts, libtool generated files, packages, makefiles.

Easy way to check - to compile MPICH2 in your home directory, install it and grep installed files for your login name.

Eugene.

Thanks.  I've fixed this in r10004.  Now the priority order for the
config file:

1. Command line

2. Environment variable

3. Home directory

4. Install directory
