Package: libruby3.0

Control: affects -1 + src:ruby-augeas
Hi Antonio et al,
during DebConf22, Antonio made cross building ruby extensions work.
That's awesome. It also means that we can not start looking into issues
further down in that stack.
ruby-augeas fails to cross build. It use pkg-config via the pkg_config
function from mkmf.rb. This function happens to use the build
architecture pkg-config and thus fails finding the requested packages
(which happen to only be installed for the host architecture). This is
not an issue in ruby-augeas, but an issue in mkmf.rb aka libruby3.0 and
it will affect many source packages.
Relevant code at:
https://sources.debian.org/src/ruby3.0/3.0.4-7/lib/mkmf.rb/#L1822
For some reason, this function says that if we are cross compiling,
pkg-config doesn't work. While that used to be true, it is not on Debian
since quite a while. We should do something like:
- (pkgconfig = with_config("pkg-config", ("pkg-config" unless
CROSS_COMPILING))) &&
+ (pkgconfig = with_config("pkg-config", CROSS_COMPILING ?
"#{DEB_HOST_GNU_TYPE}-pkg-config" : "pkg-config")) &&
Unfortunately, DEB_HOST_GNU_TYPE doesn't exist as a ruby variable here.
It probably needs to come from the host architecture's rbconfig.rb. I
checked and unfortunately, rbconfig.rb doesn't have any variable that
would know the right value. It has CONFIG['arch'], which is more like
DEB_HOST_MULTIARCH (and that happens to be correct everywhere except
any-i386). It also has CC valued "#{DEB_HOST_GNU_TYPE}-gcc" and we may
be able to dissect that.
I think the best solution here would be adding CONFIG['PKG_CONFIG'] to
rbconfig.rb and using that. I happen to not know how to implement that.
Does the approach sound reasonable? Would it be upstreamable?
Helmut

[ Antonio Terceiro ]
* Use current Ruby version as baseruby for crossbuilding.
This fixes crossbuilding Ruby when it's not the default Ruby version.
* rbconfig, mkmf: call foreign pkg-config when cross compiling
(Closes: #1019520)
* libruby3.1: depend on packages that used to be provided by ruby2.7.
This allows *ruby2.7 to be removed after upgrades from bullseye where
the user has installed packages that depend on either ruby-webrick or
ruby-sdbm.
* debian/rules: remove extension build directories.
This should make libruby3.1 cross-installable, because those directories
contains files that are architecture-dependent. Also, installing source
files and build scripts for extensions makes no sense (and we already
remove them for individual Ruby packages).
.
[ Vagrant Cascadian ]
* debian/rules: Strip the build path from rbconfig.rb
