Backport #6051: Rename ruby-1.9.pc to ruby.pc

• Status: Closed
• Assignee: -

[vo.x (Vit Ondruch)]

Could you please remove the version from ruby-1.9.pc? PKG_CHECK_MODULES provides mechanisms for selecting or constraining versions of the modules, but this mechanism is defeated when the module name includes its version number. "ruby-1.9.pc" should be renamed "ruby.pc" so that, IFF the user needs it, statements like:
PKG_CHECK_MODULES(RUBY, [ruby >= 1.9],[...]
can be used.

Originally reported as https://bugzilla.redhat.com/show_bug.cgi?id=789532

Optionally, configuration "--program-prefix" or "--program-suffix" could be used to modify the ruby.pc's filename if more ruby versions are installed on one computer. I can take look into this issue if you prefer.

I can see the need to support parallel installs of versions of the ruby interpreter on a host to support existing scripts.

I don't see the need to support multiple development environments on a single host for developers writing new extensions. IMO the .pc file should describe the preferred version, typically the latest version.

Perhaps the ruby.pc file could be in a ruby-versioned location with the latest one softlinked into ${libdir}/pkgconfig/ruby.pc? That way, if a developer really needs it, they can use PKG_CONFIG_PATH to pick up an alternate one.

I support ruby.pc

It is the simplest solution. I am not a fan of versioned .pc files at all (when the versioning is part of the name).

It is not even consistent - there would not be a ruby-1.8.pc nor a ruby 1.8.7.pc nor a ruby 1.9.4.pc file.

.pc files already contain the version of the program, so it is useless to put the name as filename as well.

Also, developers who want to use multiple versions can also compile into versioned directories.

I use this to compile into

/Programs/Ruby/VERSION_HERE

So I have:

/Programs/Ruby/1.9.3
/Programs/Ruby/1.8.7p358

And so on, with subdirs like lib/ include/ bin/ there. And my ruby scripts
switch, a bit similar to how RVM does it, between these versions as I need
it.

Has this issue slipped through the cracks? I was really hoping that a clean ruby.pc would hit Fedora distributions before the next graphviz release.

I see many versioned pc files in pkgconfig directories, why are they?
