blead perl cygwin dl library missing || strawberry perl mingw and cygwin
don't mixby default cygwin will import the path of the system into the
cygwin shell. I found that I could not build perl build properly because it
was mixing strawberry and cygwin components. To resolve the -ldl; (i
ultimately left it in), I removed all the strawberry paths from my PATH env
before running configure. ie. "export PATH=/usr/local/bin:/usr/bin" You
will see that configure no longer finds the strawberry binaries and default
settings provide a working build.
#31999: Under cygwin, cygwin's 'cpan' is used instead of Strawberry's
'cpan.bat' <https://rt.cpan.org/Ticket/Display.html?id=31999> - other
people apparently want Strawberry in their cygwin, "Strawberry is not
compatible with cygwin. Closing."
I was able to produce a 5.21.3 that worked; issue being all the MyConfig.pm
and other setting which were pointing to strawberry perl's env. which is
resolved by overriding HOME and creating a basic empty config; followed by
cpan: o conf init.
export HOME=/cygdrive/d/working/perl/build
mkdir $HOME/.cpan/CPAN/
echo "\$CPAN::Config->{cpan_home}='$HOME/.cpan';" > $HOME/.cpan/CPAN/MyConfig.pm
the issue now is that I can't install gpg using the cygwin64 installer; it
isn't available, which shouldn't be a problem really. But cpan keeps
saying "Press SPACE and ENTER to disable gpg" repeatedly, no matter how
hard I stand on space, enter, and space+enter together. I guess I'm going
to play with config file modifications...maybe even point it at
strawberry's gpg. But I wanted to mention I got perl blead built and that
there is a strange infinite loop in the questioning of the gpg tool?
thanks.
