Rolling back cmake from 3.17.3-2 to 3.14.5-1 seems to have resolved
the problem.
Any idea why no one else seems to be seeing this problem with
3.17.3-2?
I assume you had an incomplete upgrade.
what is the output of "cygcheck cmake" ?
I rolled back forward to 3.17.3-2 and verified that 3.17.3-2 still
shows the problem:
$ cygcheck cmake
Found: C:\cygwin64\bin\cmake.exe
C:\Program
Files\OpenJDK\jdk-13\bin\api-ms-win-core-rtlsupport-l1-1-0.dll
this is strange
Can you try also
strace -o cmake.out /usr/bin/cmake --version
I expect an error with a specific shared library
Yes, earlier in the thread I reported running with strace and
identifying a specific symbol that was missing, apparently from the
stdc++ library:
This seems to be the crux of it. That entry point is simply not in the
g++ shared library. I have not figured out why this cropped up today,
since it is not present in the current (10.2.0-1) or previous
(9.3.0-2) versions. I will trying going back to 7.4.0.1, but it's hard
to imagine it's been gone so long and I haven't seen the problem
before today.

_ZNSt19basic_ostringstreamIcSt11char_traitsIcESaIcEEC1Ev is the symbol
that popped up in the strace error dialog.
