Bug Information

Subject: Circular dependency
Download (untitled) / with headers
text/plain 593b
When I look into the Makefile generated by 'perl Makefile.PL' of CPANPLUS-0.9134, then I find there: PREREQ_PM [...] CPANPLUS::Dist::Build=>q[0.60] And when I look into the Makefile of CPANPLUS-Dist-Build-0.70, then I find PREREQ_PM [...] CPANPLUS=>q[0.84] But do you not think that there are situations where this really is a circular dependency and should be avoided? I need to investigate why the cpan shell has difficulties to resolve the circular dependency when one of the dependencies is already fulfilled, will do so ASAP, but for now I'm curious what you think about it. Thanks,

Hi, Yeah, CPANPLUS::Dist::Build only gets added as a prereq if it is already installed. But it was getting blindly added. https://github.com/jib/cpanplus-devel/commit/0ba41761a Should at least limit that. I don't think I will be able to get around to looking at this properly until v5.18.0 is out.

No problem because meanwhile I've added an explicit protection to CPAN.pm for this case: https://metacpan.org/source/ANDK/CPAN-2.00-TRIAL/lib/CPAN/Distribution.pm#L2668 -- andreas
