[debian-mysql] Bug#825086: Package links against libmysqlclient_r

[Robie Basak]

Package: libmysql++3v5
Version: 3.2.2+pristine-1
Tags: patch
User: ubuntu-devel at lists.ubuntu.com

Dear Maintainer,

Please stop linking against libmysqlclient_r and link directly against
libmysqlclient instead.

Your package currently links against libmysqlclient_r. libmysqlclient_r
was the thread-safe version of libmysqlclient in previous MySQL
releases. However, libmysqlclient has been itself been made thread-safe
since before the current libmysqlclient18. Thus libmysqlclient_r is
currently deprecated and provided as a compatibility symlink only, and
will disappear in MySQL 5.7. This change can be made now, in advance of
a possible future transition to libmysqlclient20, which does not provide
the _r variant.

In Ubuntu, we have done this with the attached quilt patch, which I
believe is also applicable to Debian.

Thanks,

Description: use libmysqlclient instead of libmysqlclient_r
 The former supersedes the latter which no longer exists in MySQL 5.7. Patch
 both the m4 macro and the configure script directly since autoreconf fails
 (some m4 macros missing from the source tree?)
