RE: [gentoo-dev] IF YOUR EBUILD USES PERL, PLEASE READ

[David Wilde]

Not sure if this is way OT, but I'm trying to emerge koffice-1.2_rc1.ebuild
right now and I've been getting access violations building ImageMagick.  It
started with an access denied to
/usr/lib/perl5/site_perl/5.6.1/i686-linux/auto/Image then Image/Magick then
../Image and ../Image/Magick.  I created those directories and now am
getting this:

----------------------------- ACCESS VIOLATION SUMMARY

LOG FILE = "/tmp/sandbox-imagemagick-5.4.7-2899.log"

Not sure if this has anything to do, but I know that ImageMagick uses the
MakeFile.PL for PerlMagick, and that looks like what is going on here.  I
would cc this to the ImageMagick package maintainer as well, but I don't
know who that is.  TIA

Sorry for the caps, but sometimes it's the surest way to get attention.

If your ebuild uses perl, there are some things you need to be aware of.
Perl 5.6.1's default MakeMaker module, that portion that creates the make
file from the perl Makefile.PL file, was flawed. Although it didn't violate
the sandbox, it doesn't always honor your target build directories. It also
failed to recognize build syntax that it was supposed to understand, such as
not always honoring the PREFIX you passed it. Because the potential harm
outweighed the mess I have now, this has been fixed for future/current
users. THIS ONLY AFFECTS EBUILDS THAT USE PERL MAKEFILE, NOT EBUILDS THAT
MERELY COMPILE AGAINST PERL'S LIBRARIES/BINARIES.

The result? If your ebuild at any point generates a perl module as an add
on, and you are manually passing it a "perl Makfile.PL" instead of
incorporating the perl-modules eclass, it *will* break. These bugs are
getting assigned to me right now, and I am fixing them, but I wanted to make
you aware should you have a new release come up and you don't check to see
if any changes were made to the ebuild since last time.

If you need a piece-meal example of incorporating the perl-module.eclass, I
would recommend looking at the (masked) cyrus-imapd ebuild. I have rewritten
the portion that deals with the perl module and included the inherit
perl-module line to make it work. It isn't pretty, but it is using the
eclass fully.

Please ping me if you have any questions, happy to answer, sometimes even
coherenly. =:)

I would strongly encourage using the inherit perl-module if at all possible
(and of course applicable).
