Hi,
I am doing a review for a ruby gem package that includes a library
written in C (https://bugzilla.redhat.com/show_bug.cgi?id=497640) and
there are problems with proper generation of the debuginfo package. It
cannot find the source files, because the paths in the debugsources.list
contains the "ext/<libname>" part twice and that's wrong.
+ /usr/lib/rpm/find-debuginfo.sh
--strict-build-id /home/dan/rpmbuild/BUILD/rubygem-RedCloth-4.1.9
extracting debug info
from /home/dan/rpmbuild/BUILDROOT/rubygem-RedCloth-4.1.9-3.fc10.x86_64/usr/lib64/ruby/site_ruby/1.8/x86_64-linux/redcloth_scan.so
cpio:
rubygem-RedCloth-4.1.9/usr/lib/ruby/gems/1.8/gems/RedCloth-4.1.9/ext/redcloth_scan/ext/redcloth_scan/redcloth_attributes.c: Cannot stat: No such file or directory
cpio:
rubygem-RedCloth-4.1.9/usr/lib/ruby/gems/1.8/gems/RedCloth-4.1.9/ext/redcloth_scan/ext/redcloth_scan/redcloth_attributes.c.rl: Cannot stat: No such file or directory
<snip>
This is because .%{geminstdir}/ext/redcloth/*.{c,ri} contains #line directive.
For example, from redcloth_attributes.c:
-----------------------------------------------------------------
10 #line 15 "ext/redcloth_scan/redcloth_attributes.c.rl"
11
12
13
14 #line 15 "ext/redcloth_scan/redcloth_attributes.c"
-----------------------------------------------------------------
In such case debuginfo tries to pick up files #line directive points to.
So this is not rubygem specific.
The easiest solution is something like
-----------------------------------------------------------------
%install
rm -rf %{buildroot}
# For short-circuit
rm -rf .%{geminstdir}/ext/redcloth_scan/ext/redcloth_scan
..
..
cp -a .%{gemdir}/* %{buildroot}%{gemdir}
..
..
# For debuginfo
mkdir -p .%{geminstdir}/ext/redcloth_scan/ext/redcloth_scan
cp -p .%{geminstdir}/ext/redcloth_scan/*.{c,rl} \
.%{geminstdir}/ext/redcloth_scan/ext/redcloth_scan
-----------------------------------------------------------------
