G'day Mario,

I saw this being discussed in the CB, but the data is a bit too big for there. I attempted installation of MCE and MCE::Shared on Cygwin and MSWin. Cygwin was completely successful. MSWin didn't pick up the latest (1.883) version of MCE, nor the latest (1.880) version of MCE::Shared. Details follow.

Cygwin

Cygwin (on Win10) with Perl v5.36.0 (Perlbrew):

cpan[1]> install MCE
...
  MARIOROY/MCE-1.883.tar.gz
  /usr/bin/make -- OK
...
  MARIOROY/MCE-1.883.tar.gz
  /usr/bin/make test -- OK
...
  MARIOROY/MCE-1.883.tar.gz
  /usr/bin/make install  -- OK

cpan[2]> install MCE::Shared
...
  MARIOROY/MCE-Shared-1.880.tar.gz
  /usr/bin/make -- OK
...
  MARIOROY/MCE-Shared-1.880.tar.gz
  /usr/bin/make test -- OK
...
  MARIOROY/MCE-Shared-1.880.tar.gz
  /usr/bin/make install  -- OK
[download]

I'm set up as a CPAN Tester on this platform; green swatches in the post, i.e. awaiting matrix update. :-)

MSWin

Windows 10 with Strawberry Perl v5.26.3:

Microsoft Windows [Version 10.0.19045.2364]
(c) Microsoft Corporation. All rights reserved.
...
cpan> install MCE
Database was generated on Tue, 03 Jan 2023 22:15:36 GMT

MCE is up to date (1.882).

cpan> install MCE::Shared
...
  MARIOROY/MCE-Shared-1.879.tar.gz
  C:\Users\ken\local\opt\strawberry_perl\5_026_003\install\c\bin\gmake
+.exe -- OK
...
  MARIOROY/MCE-Shared-1.879.tar.gz
  C:\Users\ken\local\opt\strawberry_perl\5_026_003\install\c\bin\gmake
+.exe test -- OK
...
  MARIOROY/MCE-Shared-1.879.tar.gz
  C:\Users\ken\local\opt\strawberry_perl\5_026_003\install\c\bin\gmake
+.exe install UNINST=1 -- OK
[download]

So, MCE v1.883 wasn't found/identified/whatever and v1.882 was up to date; and, MCE::Shared v1.880 wasn't found/identified/whatever and v1.879 was installed successfully.

I'll be happy to test further; let me know.
