[Pkg-javascript-devel] Bug#773341: libuv: link against -pthread to fix underlinking issues

[Logan Rosen]

Package: libuv
Version: 0.10.28-5
Severity: normal
Tags: patch
User: ubuntu-devel at lists.ubuntu.com

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.

Logan Rosen
