on a 64bit system the shared and shared-compat packages can coexist, while they cannot on a 32bit system

[Rene' Cannao']

On a 64bit system:

[root@ami-64 x86_64]$ rpm -ql Percona-Server-shared-51.x86_64 | grep libmysqlclient_r.so.16
/usr/lib64/libmysqlclient_r.so.16
/usr/lib64/libmysqlclient_r.so.16.0.0
/usr/lib64/mysql/libmysqlclient_r.so.16
/usr/lib64/mysql/libmysqlclient_r.so.16.0.0

[root@ami-64 x86_64]$ rpm -ql Percona-Server-shared-compat.x86_64 | grep libmysqlclient_r.so.16
/usr/lib64/libmysqlclient_r.so.16
/usr/lib64/libmysqlclient_r.so.16.0.0

On a 32bit system it is impossible to install them both:

Hello,

I've tested with 5.1.63 (latest) but I was unable to install -shared-compat together with the shared package, not even in 64 bits -- in other words I coudn't reproduce the first case.

Note the way the shared-compats packages are supposed to be used is to be used instead the shared package, so they shouldn't be installed side by side but one in place of the another. Note that this is different as how they work for the 5.5 branch currently.

A solution would be to change the name of the 5.1 branch -shared-compat packages to Percona-Server-shared-compat-51 and allow these to be installed side by side with the -shared package. The name of the package is to be changed so in the repositories it can be chosen instead of the 5.5 branch.

Ignacio,
with 5.1.63 things aren't solved, but just they act on a different way.

Please review the attached log:
shared-compat can NOT be installed instead of -shared .
Both Percona Server and Client require -shared , and they fail to install with -shared-compat .

This is reproducible on both 32 and 64 bit architecture.

@Rene,

shared-compat and shared cannot be installed on 5.1.x due to libmysqlclient.so.16 being in both.

Now, if you need shared-compat for the older versions (libmysqlclient.so.{12,14,15}) then you can install Percona-SQL-shared-compat.x86_64 which won't conflict. (It doesn't have libmysqlclient.so.15 though)

The long term solution is to create a separate Percona-Server-shared-compat for 5.1 (or abandon Percona-Server-shared-51 and a create a singled shared compat with libmysqlclient.so.{12,14,15,16} ). You can track it here: lp:893860
