Thanks for your reply.

The problem was due to mismatch of Qt libs versions.
After that we solved issues with incompatibility of libs that are coming along with Salome (sip) and those that were installed
in the system.

But we still have some issues: We cannot pack commercial PyQt with VendorID in the hidden library.
If i get it right, there is a mention of this possibility in the oficial document "VendorID - Signing Python Interpreters and Modules"
(p.3.1 Creating Restricted Extension Modules).

To figure out how Vedor ID works i created foo.py script that contained couple of functions,
1 class and also foomodule.c file (identical to the one in example Reference Guide 3.1 Creating Restricted Extension Modules)

After that we tried to create a library with the help of commands:

>> python ~/VendorID-1.0.0/sib/sib.py -u foo.py

the folder build_foo is created with files makefile, __main__.c, frozen.c in it

>> make

And we got the next message in the terminal:

gcc -pthread -Xlinker -export-dynamic __main__.o foo.o frozen.o -o foo -lpthread -ldl -lutil -lm -L/usr/local/lib -lpython2.6

collect2: executing lt finished with return code 1
make: *** [foo] Error 1

The issue with PySide still remains: PySide is referring to a lib that has to be located in the system folder /usr/lib/i386-linux-gnu/libpyside-python2.7.so, while in our case all paths should be relative.

       -h, --help
              show this help message and exit

       -f, --force
              force rebuild of byte-code files even if timestamps are up-to-date

              specify Debian package name whose files should be bytecompiled

       -V VRANGE
              force  private  modules to be bytecompiled with Python 3 version from given range, regardless of the default Python 3 version in the
