Hi, Two people have reported a sudden inability to shell out from Perl in Windows https://stackoverflow.com/questions/72503807/perl-calls-using-system-abruptly-start-failing > This week one of my standard perl [Strawberry perl 5, version 32, > subversion 1 (v5.32.1) built for MSWin32-x64-multi-thread] scripts started > failing. I tracked it down to a failing backtick operation. > > Investigation showed that all the system-type calls, backtick, qx, pipe > open, are failing. I tried building a debug version of perl, and even that > fails, as the build process uses miniperl, which has the same problem. > > ..\miniperl.exe -I..\lib ..\make_ext.pl "MAKE=nmake -nologo" > --dir=..\cpan --dir=..\dist --dir=..\ext --nonxs > Can't spawn "cmd.exe": No such file or directory at ..\make_ext.pl line > 580. > Can't spawn "cmd.exe": No such file or directory at ..\make_ext.pl line > 582. > Unsuccessful make(dist/if): code=65280 at ..\make_ext.pl line 584. > > I tried defining PERL5SHELL (full path to cmd, pwsh in place of cmd), > turning off malware protection, everything I could think of reverting. > > So, the actual question: Does anyone have a suggestion for how I can track > this down? It was working on Thursday, and there have been no system > updates since then [OS version 10.0.22000]. > Has this happened to anyone else? I have no issues with SP 5.32.1 on Win11. - EricThread Next
