[mpich-discuss] Cygwin+Mpich2: Internal Error: Failed to convert MPI_INTEGER value to hex!

[Mengda Wu]

Hello all,

   I am trying to compile mpich-3.1.2 under Cygwin 64bit. I am using the
mingw64- x86_64-gcc-g++ and mingw64-x86_64-gcc-gfortran compilers, i.e. the
mingw compilers shipped in the latest Cygwin. I encountered an internal
error "Failed to convert MPI_INTEGER value to hex!" when configuring.
