[New-bugs-announce] [issue43229] freeze searches libpython3.9.so in /usr/lib instead /usr/lib/x86_64-linux-gnu

[Christian Bachmaier]

New submission from Christian Bachmaier <chris at infosun.fim.uni-passau.de>:

Now that the patch from issue 42591 (https://bugs.python.org/issue42591), i.e., msg383154 from 12/16/20  has made it to Ubuntu 20.04 with packet version python3.9.1-1, there show some problems with that.

I did:
> freeze/freeze.py -o frozen helloworld.py
> cd frozen
> make

This delivers a linker error
...xml__parsers.o M_xml__parsers__expat.o M_xml__sax.o M_xml__sax___exceptions.o M_xml__sax__expatreader.o M_xml__sax__handler.o M_xml__sax__saxutils.o M_xml__sax__xmlreader.o M_xmlrpc.o M_xmlrpc__client.o M_zipfile.o M_zipimport.o /usr/lib/libpython3.9.so -lexpat                       -L/usr/lib -lz                        -lexpat  -lcrypt -lpthread -ldl  -lutil -lm -lm  -o helloworld
x86_64-linux-gnu-gcc: error: /usr/lib/libpython3.9.so: No such file or directory
make: *** [Makefile:1234: helloworld] Error 1

The linker searches libpython3.9 in /usr/lib instead in /usr/lib/x86_64-linux-gnu . The "hot-fix"
> ln -s /usr/lib/x86_64-linux-gnu/libpython3.9.so /usr/lib/libpython3.9.so
fixes that, but brings another error:

> freeze/freeze.py -o frozen helloworld.py
> cd frozen
> make

@Victor: I know there are alternatives to freeze, however, I have to keep a larger legacy project running, and I am not that expert. Maybe you could have a look on the above.
