in thread Problem with wxperl/constructors.pm

Initially, I have installed ActivePerl without even searching what is needed to be used for Windows. Then I come to know that Strawberry is much needed for Windows. Then went ahead installed it. Now, I have the batch files to switch back and forth to Active and Strawberry. I have switched back to Active to install IPC::Run. The following error is being thrown in the console, but also displays the IPC::Run is installed successfully.

C:\Perl64>cpanp -i IPC::Run It looks like you don't have a C compiler and make utility installed. + Trying to install dmake and the MinGW gcc compiler using the Perl Package Man +ager. This may take a a few minutes... ppm.bat install failed: Can't find any package that provides MinGW It looks like the installation of dmake and MinGW has failed. You wil +l not be able to run Makefile commands or compile C extension code. Please che +ck your internet connection and your proxy settings!

    I have verified that the wxPerl-Constructors Module from PPM is already installed. I did it before when I used to work on Active Perl.

    wxPerl-Constructors Version: v0.0.4 CPAN: http://search.cpan.org/dist/wxPerl-Constructors-v0.0.4/ Installed files: C:/Perl64/html/site/lib/wxPerl/Constructors.html C:/Perl64/html/site/lib/wxPerl/Constructors/argmap.html C:/Perl64/html/site/lib/wxPerl/Constructors/doc.html C:/Perl64/man/man3/wxPerl.Constructors.3 C:/Perl64/man/man3/wxPerl.Constructors.argmap.3 C:/Perl64/man/man3/wxPerl.Constructors.doc.3 C:/Perl64/site/lib/auto/wxPerl/Constructors/.packlist C:/Perl64/site/lib/wxPerl/Constructors.pm C:/Perl64/site/lib/wxPerl/Constructors/argmap.pm C:/Perl64/site/lib/wxPerl/Constructors/argmap.pod C:/Perl64/site/lib/wxPerl/Constructors/doc.pod

[Corion]: Hmm - no, that outputs 1 for me on 5.14 - perl -wle "my $x = qq(\x{200b}); warn $x; warn length $x"
[hippo]: Smart - I'll give that a go. Thanks.
[hippo]: Ah
[Corion]: But maybe there is some other Unicode string that will be true but have a zero width
[hippo]: For explanation, I've seen this construct in someone else's code (no names, no pack drill) and couldn't think of a situation to trigger it.
[Corion]: You'll have to look somewhere esoteric for that. Maybe some tied variable or special dualvar can also trigger that. But it's certainly not a common occurrence
[Corion]: And on 5.20, the following also outputs no find:perl -wle 'for my $x ("\x{2000}".."\ x{1fffff}") { if( $x && ! length $x ) { warn qq(<$x>); warn length $x; die } }'
[Corion]: (this time on Unix)
[hippo]: Understood. I'll have to go through the code and see if it's doing anything fancy with ties, dual-vars or non-scalars. In the end, it's probably a bug though.
