install on ubuntu with Mandrake 10.1 xml

Posted by guillaume niel at February 06. 2006

Hi,
I try to install salome on ubuntu with Mandrake 10.1 xml file. When I launch the wizard, there is a message saying that I have a newer version of python (2.4 for 2.3.4 required) but I go on.
After installation, I do a 'source salome.sh', and then I do a runSalome. Here is the message I get after that :

Searching for a free port for naming service: 2810 - Ok
Traceback (most recent call last):

What have I to do ?

Thanks for your help

Hello,

When you do install you choose to install native python (i.e. from your OS) and omnirob from SALOME distibutive..

It seems that your native python was compiled without support of UNICODE (or something similar). Precompiled omnirob from CD was built with python with this support. Because of this there is undefined reference.

The easiest way to solve is to install also binaries of python 2.3.4 from SALOME distributive. Please choose option "install from binaries" for Python. In this case it should be OK.

If you prefer in any case to use your native python, other way is to rebuild omniOrb with your python from scratch.

Best regards,

Sergey.

Hi,

The explanation is probably : Salome has been built with a python configured with UCS2 unicode (default configuration for python 2.3).
You use a python2.4 configured with UCS4 unicode so you can't find entry points for UCS2.
You need a python with UCS2 unicode.

I use a Debian installation (sarge). Python 2.3 is configured by default with UCS4 so perhaps, you could have a better chance with a Debian Salome install.
But beware with the potentially incompatible binary API between 2.3 and 2.4.

Regards
Christian

Hi,
I managed to install salome with the Mandrake10.1 config file by installing Python 2.3.4 sources in the salome Wizard...
thanks for your help
