As a very late follow up, here's what the rules file would have looked
like, paired with ${db-*:Depends} fields in control:
[...]
binary binary-arch: install
dh_installchangelogs -a ChangeLog
dh_installdocs -a
dh_movefiles -a
# compute shlib deps for libyada
dh_shlibdeps -a
# move plugins in place and compute deps for them
mv debian/tmp/usr/lib/libyada_*.so* debian/libyada4/usr/lib
dpkg-shlibdeps -T"debian/libyada4.substvars" -pdb-postgres -edebian/libyada4/usr/lib/libyada_pgsql.so.4
dpkg-shlibdeps -T"debian/libyada4.substvars" -pdb-mysql -edebian/libyada4/usr/lib/libyada_mysql.so.4
dpkg-shlibdeps -T"debian/libyada4.substvars" -pdb-sqlite -edebian/libyada4/usr/lib/libyada_sqlite3.so.4
# remove the libc dependency (already covered by dh_shlibdeps)
perl -i -pe 's/libc\d \(>= [0-9.-]+\), // if /^db-/' debian/libyada4.substvars
# make sure there's only one dep per plugin (otherwise A | B | C won't work)
if egrep '^db-.*,' debian/libyada4.substvars ; then exit 1 ; fi
dh_strip -a
dh_compress -a
dh_fixperms -a
dh_makeshlibs -a
dh_installdeb -a
dh_gencontrol -a
dh_md5sums -a
dh_builddeb -a
[...]
I went the other way though, there's now separate packages for the sql
backend wrappers. (Which promptly triggered a "circular dependency
hell" bug report - #414691.)
