Which version of MPICH are you trying to build? Can you send us the config.log? On Jun 17, 2013, at 1:07 PM, Haroogan <[email protected]> wrote:

Hello,

I'm trying to build MPICH under MinGW-w64 based on GCC 4.8.0 (POSIX Threads), and here is what I get:

configure: error: Unable to determine the size of MPI_BSEND_OVERHEAD"

Any ideas? _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
