Bug#949789: libcdb-file-perl FTCBFS: computes a build architecture ARCHLIB
Source: libcdb-file-perl
Version: 1.00-1
Tags: patch
User: debian-cross@lists.debian.org
Usertags: ftcbfs
libcdb-file-perl fails to cross build from source, because its ARCHLIB
variable is computed for the build architecture rather than the host
architecture. We've already seen this pattern in #949266. The same fix
works here.
Can we take the opportunity to step back? Clearly embodying these runes
into many packages is going to cause pain down the road. They're hard to
remember and longish. If setting up ARCHLIB is a common thing, then
maybe it should be centralized somehow? dpkg provides
/usr/share/dpkg/*.mk. Maybe perl should do something similar? Could
there be some perl.mk to be included in debian/rules that sets up
ARCHLIB?
I've X-Debbugs-Cced debian-perl@l.d.o to get an answer to the latter.
Please wait a little before applying my patch: I hope we can centralize
it somehow.
Helmut
