Bug#457915: libmysqlclient15-dev: relocation R_X86_64_32S against `client_errors'...recompile with -fPIC

[Marc J. Driftmeyer]

Package: libmysqlclient15-dev
Version: 5.0.51-1
Severity: important

Compiling against KDE 4 Trunk revealed that the amd64 build produces bad
value reads in /usr/lib/mysql/libmysqld.a

To be exact:

Linking CXX shared module ../../../lib/libqsqlmysqlembedded.so
/usr/bin/ld: /usr/lib/mysql/libmysqld.a(client.o): relocation
R_X86_64_32S against `client_errors' can not be used when making a
shared object; recompile with -fPIC
/usr/lib/mysql/libmysqld.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
make[2]: *** [lib/libqsqlmysqlembedded.so] Error 1
make[1]: ***
[akonadi/server/sqlplugin/CMakeFiles/qsql_mysql_embedded.dir/all] Error
2
make[1]: *** Waiting for unfinished jobs...

Package KDEPIM for KDE 4.0 build fails for both 5.0 and 5.1
experimental.

Suggestion: Build packages explicitly with the -fPIC flag.

I've been working on this bug upstream where it's causing problems with
libndbclient. We have a fix around, but it's just for libndbclient. I'm
glad to see there's a larger issue, and I'll include this on the
upstream bug, which is http://bugs.mysql.com/bug.php?id=29791

Quoting policy:
As to the static libraries, the common case is not to have relocatable
code, since there is no benefit, unless in specific cases; therefore
the static version must not be compiled with the `-fPIC' flag. Any
exception to this rule should be discussed on the mailing list
_debia...@lists.debian.org_, and the reasons for compiling with
the `-fPIC' flag must be recorded in the file `README.Debian'. [3]

If you need a libmysqld which can be used by shared objects, then please
add libmysqld_pic.a in addition to the non-PIC version.

Cheers,
Julien
