Subject: [ruby-core:43305] [ruby-trunk - Feature #6052] please add vendorarchdir and vendorlibdir to ruby.pc


Issue #6052 has been updated by Bohuslav Kabrda.


Hi, I'm finding it really hard to follow some of the changes that you have done here. I'm not implying that anything is wrong, maybe I don't get something, so please take this rather as a question, but the settings you now provide in ruby.pc are not well for Fedora (I don't know about other platforms, but let me explain):

Current state:

rubylibprefix=@rubylibprefix@
rubylibdir=${rubylibprefix}/${ruby_version}
vendordir=${rubylibprefix}/vendor_ruby
sitedir=${rubylibprefix}/site_ruby
rubyarchdir=${rubylibdir}/${arch}
vendorarchdir=${vendordir}/${sitearch}
sitearchdir=${sitedir}/${sitearch}

The problem is that vendorarchdir gets translated to ${rubylibprefix}/vendor_ruby/${sitearch}, which then gets translated to /usr/share/ruby/vendor_ruby/${sitearch}, which seems wrong (platform specific files get under /usr/share) - it should be /usr/lib[64]/ruby/vendor_ruby, so something like %{libdir}/vendor_ruby, shouldn't it?

Am I missing something or is this really an issue? If so, would it be possible to backport it to 1.9.3 branch?

Thank you!

  this issue separates the issue of vendorarchdir from the ruby-1.9.pc -> ruby.pc renaming issue).

[John Ellson]
The current ruby-1.9.pc doesn't provide a value for "vendorarchdir"
and so is insufficient for packages like graphviz to build ruby extensions
without still resorting to ruby's (ever changing) RbConfig (nee: Config)
mechanism.

[Bohuslav "Slavek" Kabrda]
- Defining vendorarchdir and vendorlibdir is not a problem but how would it
solve the problem with graphviz? And how would you propose to use these -
passing them as additional Cflags?

[John Ellson]
No, not Cflags.  The value is need for installation, not compilation.

Assuming ruby.pc contains a line like:
           vendorarchdir=${libdir}/ruby/vendor_ruby

configure.ac would extract it by using something like:
           PKG_CHECK_MODULES(RUBY, [ruby >= 1.9],[
                RUBY_INSTALL_DIR=`pkg-config --variable vendorarchdir ruby`
                AC_SUBST([RUBY_INSTALL_DIR])
           ],[
                #deal with pre 1.9 ruby's
           ])
