Open MPI broken (November 2 release) ?
I tried re-compiling some things after updating to openmpi 4.0.5 and am getting some unexpected failures from mpifort and mpicc: $ mpifort -O3 testmpi.f90/usr/lib/gcc/x86_64-pc-cygwin/10/../../../../x86_64-pc-cygwin/bin/ld: cannot find -lhwloc/usr/lib/gcc/x86_64-pc-cygwin/10/../../../../x86_64-pc-cygwin/bin/ld: cannot find -levent_core/usr/lib/gcc/x86_64-pc-cygwin/10/../../../../x86_64-pc-cygwin/bin/ld: cannot find -levent_pthreads/usr/lib/gcc/x86_64-pc-cygwin/10/../../../../x86_64-pc-cygwin/bin/ld: cannot find -lzcollect2: error: ld returned 1 exit status Denny@DESKTOP-BEBCMC4 ~/MPI_tests$ I have some working executables from October 26, so I assume there is a problem or something else that I need to update.

[ANNOUNCEMENT] Updated: gmp-6.2.1-1
GNU Multiple Precision Arithmetic Library = GMP is a free library for arbitrary precision arithmetic, operating on signed integers, rational numbers, and floating point numbers. There is no practical limit to the precision except the ones implied by the available memory in the machine GMP runs on. GMP has a rich set of functions, and the functions have a regular interface. --8<---cut here---start->8--- Changes in GMP 6.2.1 BUGS FIXED A possible overflow of type int is avoided for mpz_cmp on huge operands. Overflows are more carefully detected and reported for mpz_pow_ui. A bug in longlong.h for aarch64 sub_ddmmss, not affecting GMP, was healed. Mini-GMP: mpz_out_str and mpq_out_str now correctly handle out of range bases. FEATURES C90 compliance. Initial support for Darwin on arm64, and improved portability. Support for more processors. SPEEDUPS None, except indirectly through recognition of new CPUs. --8<---cut here---end--->8--- -- *** CYGWIN-ANNOUNCE UNSUBSCRIBE INFO *** If you want to unsubscribe from the cygwin-announce mailing list, look at the "List-Unsubscribe: " tag in the email header of this message.

I have also found the output of "cronevents" helpful.

What's the output of "cygrunsrv -V -Q cron"?
What are the file permissions on /var/log/cron.log? ("ls -l
/var/log/cron.log"). The uid running cron needs write permission there.
I run cron from the Local System account, which can setuid to other users.
I don't know the circumstances where one should still use a non-SYSTEM
account with Windows 10, but they aren't mine and I recommend running
as SYSTEM if possible.
