Master branch fails to build when not using system perl #18

Closed mperry2 closed 9 years ago

mperry2 commented 9 years ago

I tried and failed to build clusterssh from the master branch today. I use perlbrew to manage a perl installed into my home directory. I attempted to build clusterssh with that perl.

"perl Build.PL" completes successfully, but "./Build" fails and produces output that looks like it's using the system perl in /usr/bin/perl.

Exception::Class is installed.

mperry2@devserver:~/dev/cssh/clusterssh-master$ perl -MException::Class -E 'say "OK"'   
OK

Here's my @INC which doesn't match what ./Build is looking for.

I would guess that Build runs the system Perl rather than the one in your path and the system perl doesn’t have Exception::Class. It’s a pretty common problem in my experience when having multiple versions of Perl around. I don’t know if its the correct solution but a workaround is probably to edit Build to point it to the perl you have in your how directory.

HTH,

No guess about it. That's exactly what's happening. There are files in bin_PL that are explicitly using the system perl instead of using the perl in the default path as they should. This appears to be a recent change because I didn't encounter the problem six months ago when I last installed the module.

Duncan will need to fix this which is why I opened the bug report. I don't know enough about the the module build process to feel confident submitting a patch.

I'm in the process of setting up a new system to replicate this so I can prove it is fixed later

I've pushed a code commit that fixes the problem on my (new) perlbrew install. Let me know if you have any further issues. I'll push it as a new release in a week or so when I have finished up a few other minor "tidy ups".
