[mpich-discuss] Install errors on MAC OS Sonoma: "error: expected declaration specifiers or ‘...’ before string constant"

[Douglas G Dommermuth]

I am compiling mpich 4.2.0 on a MacBook Air Apple M1 running macOS Sonoma 14.3.1.   I am using gcc and gfortran versions 13.2.0.   I get the following errors when I build MPICH:

/Applications/Xcode.app/Contents/Developer/usr/bin/make  all-am
depbase=`echo util/info.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\

It looks like errors in macOS’s command line tools.    I don’t know how to circumvent the problem.  Various text and  log files are attached in mpich2.tar.gz.   A copy of the lock.h code is also included in the zip file.

Thank you, Doug.
