[mpich-discuss] Unable to build on OSX

[Gropp, William D]

Using the current as of this morning from git, hash 1d340282 , and with CC=gcc-10 (needed to work with the corresponding version of gfortran, because gcc on OSX is really clang)

../../sources/mpich/configure --with-device=ch4:ofi --prefix=/Users/gropp/installs/mpich2-dbg

works but make ends with

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: file: lib/.libs/libmpifort.a(mpi_c_interface_nobuf.o) has no symbols

Configure and make logs attached.

(Some of the instructions on the MPICH web page for submitting bug reports sent me to unreachable github web pages)
