Mutual GNU / Linux

Can you run and post the results?

ldd /opt/ryzom/ryzom_client | grep lua

It should be something like this

liblua5.2.so.0 => /usr/lib/x86_64-linux-gnu/liblua5.2.so.0 (0x00007f8de6b51000)
libluabind.so.0.9.1 => /usr/lib/libluabind.so.0.9.1 (0x00007f8de6934000)

Also to verify ryzom_client, could you run

md5sum /opt/ryzom/ryzom_client

and see if it matches

e5c60d198d52e9882d0595156ebc2f6c  /opt/ryzom/ryzom_client

arumes@RMS-DESK:~$ ldd /opt/ryzom/ryzom_client | grep lua

    liblua5.1.so.0 => /usr/lib/x86_64-linux-gnu/liblua5.1.so.0 (0x00007f4bf3db3000)

    libluabind.so.0.9.1 => /usr/lib/libluabind.so.0.9.1 (0x00007f4bf3b96000)

    liblua5.2.so.0 => /usr/lib/x86_64-linux-gnu/liblua5.2.so.0 (0x00007f4bf07bd000)

arumes@RMS-DESK:~$ md5sum /opt/ryzom/ryzom_client

So there's no match. For now, I'll just switch back to the previous version, because I think the problem lies with the PPA, not with my system. And now that I'm switching back, I notice that the version you mentioned is the 'old' version. The latest version for 14.04 is called 2.1.0.6447-0ubuntu1, so without the "~trusty1" at the end. Now that I reverted the upgrade, Ryzom is working again:

Could you take this up with the maintainer of the PPA? Seems like that's where the problem is.

I'm sorry, I just understood what happened :p

Canonical finally updated Ryzom from Ubuntu Software Center but they applied the wrong version for Ubuntu 14.04 :( So there is a conflict between the 2 versions.

For the moment, I suggest you to uninstall the one from Ubuntu Software Center and reinstall the one from the ryzom-isv PPA.

Since I could again talk to a Canonical employee, we'll be able to fix this problem :)

Thanks for discovering it :)

The problem that was happening is the following :

They applied the client for Precise (12.04) to all Ubuntu versions.

Under Precise, Ryzom was using Luabind linked against Lua 5.1, under Trusty Luabind is compiled against Lua 5.2.

So it tries to mix both Lua 5.1 and 5.2, which is creating these crashes :s

To fix your problem, I'm compiling new versions on PPA for Precise and Trusty (version 2.1.0.6449) with no changes in code but since version is greater, it shouldn't have conflicts anymore :)

Next step is to contact the Canonical Employee and explain to her that we are using dynamic linking and she shouldn't copy Precise package for all other Ubuntu versions.
