Re: How to launch or uninstall Salome Meca 2018 in ubuntu 16.04

Hi

I had the same issue with an ubuntu 16.04 LTS on my PC; finally I found a way to start Salomé-méca:
- I went to the "$HOME/salome_meca/V2018/prerequisites/debianForSalome/lib" directory
- I've commented the 3 files "libstdc++" by adding an underscore at the name end
- now it opens

hope it works for another users

Thank Paul for confirming that, we'll look into it for the subsequent packaging.

Re: How to launch or uninstall Salome Meca 2018 in ubuntu 16.04

This is a typical issue with outdated libraries. Other apps like Matlab have the same problem. The solution is to use the libraries present on the system instead of loading new ones. You can make this work on any ubuntu distro executing the command 

LD_PRELOAD='/usr/$LIB/libstdc++.so.6' ./salome 

This command preloads that library from the system and executes Salome. However I still get some warnings:

****************************************************************
     Warning: module HYBRIDPLUGIN is improperly configured!
     Module HYBRIDPLUGIN will not be available in GUI mode!
****************************************************************
****************************************************************
     Warning: module NETGENPLUGIN is improperly configured!

****************************************************************
****************************************************************
     Warning: module GMSHPLUGIN is improperly configured!
     Module GMSHPLUGIN will not be available in GUI mode!
****************************************************************

Matlab solves this kind of problems with libraries installing a package called matlab-support which is available on the Ubuntu Universe repository. Maybe the devs of Salome should consider a similar solution.

There are other ways to avoid packaging errors on linux distros. Like using appimages, snaps or flaptak files. Those 3 options are distro-agnostic and probably require less support on the long run. It would be great if you could create a package with any of them

Re: How to launch or uninstall Salome Meca 2018 in ubuntu 16.04

Hi all,

I'm experiencing a similar install issue. Tried with Ubuntu 18.10, thought that may be the problem so I installed 18.04. Performed updates and ensured all prerequisites were properly installed.

--- Error during Salome launch ---

I'm not experienced with linux but it seems to me with the reading Ive done that the drivers are out of date [salome is looking for a different name I think]. I guess this is the reason this line works

 LD_PRELOAD='/usr/$LIB/libstdc++.so.6' ./salome

Question for Maccer would be, why does this work? And do you think there's a way we can maybe create a more permanent solution. This is only capable of being launched through terminal and has to be done every time.

Maybe a symbolic link may solve the problem. So when Salome looks for the "library/driver" it gets directed to library we had to preload.

Like i said im not experienced so that suggestion might be complete garbage. I'm going to continue looking into this but any support will be appreciated.

Re: How to launch or uninstall Salome Meca 2018 in ubuntu 16.04

Hi all,

I had the same problem after installing the Salome-Meca package on Ubuntu 18.04.2 LTS, I have followed some advice on this forum but still cannot fully solve. I run through terminal with some errors that I don't know how to fix, please can anybody help? (I would be so grateful!).

I have a warning that (SALOME_MED/MEDCouplingFieldDoubleCorbaInterface,objref) already exists and will be ignored - is this a problem and if so how do I fix it?  The modules shown below are improperly configured, does anyone know how to fix these?

Thanks,
Nick

Thanks. Had the same issue with Ubuntu 18.04.4 LTS and salome_meca 2018.0.

Re: How to launch or uninstall Salome Meca 2018 in ubuntu 16.04

Dear jdbcoles,

A more neat solution is to delete or rename libstdc++.so.6 in the salome meca installation directory.

That should be in V2019.0.3_universal/prerequisites/debianForSalome/libs

That way salome would naturally use the c++ libraries from your system.

Good luck!

 LD_PRELOAD='/usr/$LIB/libstdc++.so.6' ./salome

Hi all, that is still needed in salome_meca 9.4.0, on ubuntu 20.04
