Package: libuv Version: 0.10.28-5 Severity: normal Tags: patch User: ubuntu-de...@lists.ubuntu.com Usertags: origin-ubuntu vivid ubuntu-patch
Dear Maintainer, As you can see from the build logs for libuv (for example on amd64) [1], there are warnings from dpkg-shlibdeps such as the following: dpkg-shlibdeps: warning: symbol pthread_rwlock_rdlock used by debian/libuv0.10/usr/lib/x86_64-linux-gnu/libuv.so.0.10 found in none of the libraries This caused residual effects in Ubuntu, where getdns (a package that build-depends on libuv0.10-dev) failed to build due to undefined references to pthread symbols in the libuv.so. Although this isn't causing an FTBFS in Debian, as we use different linker flags, it is probably a good idea to apply this fix here as well in case Debian switches to ld --as-needed in the future. In Ubuntu, the attached patch was applied to achieve the following: * Link against -pthread to fix issue with ld --as-needed. Thanks for considering the patch.
