Salome V6.4.0 x86-64bits. Archlinux. doesn't work

I've tryed to install the bin file and I got this error.

$ pacman -Ss glibc
core/glibc 2.15-10 (base) [installed: 2.15-7]

$ ./Salome-V6_4_0-LGPL-x86_64.run -d -v

The problem is python scripts "SALOMEDIR=`python -c "import os; print os.path.normpath(os.path.dirname(os.path.abspath(os.path.realpath('$0'))))" 2>/dev/null`

Hi GA,

Is your archlinux installation updated? If it is so, I think the problem comes from archlinux using python3 as default, which is not compatible with python2.7

The only workaround I've found so far is to delete the symbolic link /usr/bin/python and make a new one that points to /usr/bin/python2

Anyway, you'll have to change it back to point to /usr/bin/python3 when your done using Salome.

There should be a better way, but I have not found any yet.

Hi again,

Looking througth archlinux guide about python, it mentions a workaround that works with less trouble:

It only works if the scripts use #!/usr/bin/env python, which salome does, it won't work with #!/usr/bin/python. This trick relies on env searching for the first corresponding entry in the PATH variable. First create a dummy folder.

$ mkdir ~/bin

Then add a symlink 'python' to python2 in it.

$ ln -s /usr/bin/python2 ~/bin/python

Finally put the new folder at the beginning of your PATH 

$ PATH=~/bin:$PATH ./runAppli

It seems to work great.

I've followed Ricardo's instructions on creating the link in ~/bin and edited the ./runApli script file by adding PATH=~/bin:$PATH at the beginning of the file.

As Ricardo says, it does seem to work great.

Thanks Ricardo!

Hi all,

in my case its not working: I got the following errors while running the "runAppli.sh" file.

[shor-ty@localhost appli_V6_6_0]$ ./runAppli

Searching for a free port for naming service:

I set the /bin/python link to python2 and i sucessfully could start Salome-V6_6_0-LGPL-i686.run.

Does anyone know an answer?

Hi all.

I got the installer to work by modifying a few scripts in the auto installer. Basically, it's just a matter of calling explicitely the right version of python. 

create_appli_V6_6_0.sh becomes http://pastie.org/7745587 and creates an appli.

Then runAplli in the appli directory becomes http://pastie.org/7745595

and getAppliPath.py in the same directory must point to python2 (change the first line to /usr/bin/python2)

Hope you'll find your way through this.

@Ricardo : keep in mind that your symlink will point to python3 after each python update !

Hi Gaudin, I don't see that happening? Why do you say that?

Hi Ricardo. The symlink /usr/bin/python is part of python package under arch linux. If you upgrade the package at some point this file will change and point to python3 which is arch's default. If your method stops working after an upgrade just modify the symlink again.

Hi Gaudin, 

I think you are refering to the first workaround I proposed, and you are right.

People should use the second one posted.
