As for some time now, first I have to manually fix
https://bugs.python.org/issue40350 first, i.e., use the recommended workaround
not None check for spec.loader in /usr/lib/python3.9/modulefinder.py.

Seems to work like a charm. Basically I used the same testing setup as
previously on Dec 10th under Debian testing/bullseye without step 2, as master
already contains y

Yes, unfortunately I have to keep a large old system running and there are only
few options left. It is a University learning system, where students upload
program code and then a huge amo

Dear Victor,
a simple test with the tools/freeze/hello.py example was successfull with your

The same under Python 3.9.1 (Package from Debian bullseye/testing). As the
method Py_FrozenMain is contained in the source code, maybe ist has something
to do with the build process, a change in makefile? As far as I can see, the

Christian Bachmaier added the comment:
Sorry guys, library loading of a freezed binary is different to interpreter
mode. This is a bug in freeze, or at least an undocumented missing feature of
freeze. This is no side discussion.
And, in Python 3.2 this was working! As described above, just

Same issue with external libraries under (pachted) Python 3.4.0 final on Ubuntu
14.04 LTS or Debian Wheezy/Sid.
Meader, is there any option/possibility zu use an external library (like
psycopg2.psycopg.so)from the freezed binary? I alreday tried

Martin: this is clearly a bug, as it is now (Python 3.3 onwards) impossible to
use an external module (in a .so) from a frozen binary.
The phrase please help was intended to fix the bug. If there is a new option
then this would also result in some kind

Christian Bachmaier added the comment:
The shared library is not linked into the resulting binary
by simply having an import in the Python file.
Yes. This is why (at least in Python 3.2) it must be in the right path
(subdirectory), see above.
freeze does
support adding the external library
Christian Bachmaier added the comment:
Sorry I forgot: PyRun seems only support Python 2.x.
The only other freeze tool I know for Pyhton3 code is cx_freeze. I would
prefere the vanilla freeze of the python distribution itself and as far as I
can see using cx_freeze makes more problems for me

To test what I asked for, please run freeze on this script:

Thanks for the patches. After applying issue11824-0.patch and then

under ubuntu 14.04 with python 3.4 rc3. I have attached my new site.py file,
