Package: src:ruby1.8
Version: 1.8.7.358-3
Affects: src:ruby-rmagick
Severity: critical
Tags: sid wheezy patch
X-Debbugs-Cc: debian-r...@lists.debian.org
Justification: breaks unrelated software
Hi,
ruby-rmagick now FTBFS against ruby1.8 1.8.7.358-3 in sid.
This is because ruby1.8 forced compilation with gcc-4.6, and that choice
is stored as CONFIG["CC"] on the system's rbconfig.rb.
When building ruby-rmagick, gcc-4.6 might not be available if it is not
the system's default gcc and there is no explicit dependency. Recently
some arches defaulted to gcc-4.7, but on the other hand sparc still has
gcc-4.4 and has the same issue.
The rbconfig.rb file is owned by libruby1.8 but not all its users may
want to install a compiler. ruby-rmagick (and presumably others) has a
Depends on ruby1.8-dev which may be a better place for this; that
package depends on a libruby1.8 of the same package version.
So I think the best solution is for ruby1.8-dev to add a Depends on
gcc-4.6. Otherwise it only Depends on libc6-dev, which in turn
Recommends any c-compiler where gcc-4.6 might not have otherwise been
chosen as the preferred one.
