python/gnucash weirdness: missing PyOS_getsig

[Thomas Klausner <tk%giga.or.at@localhost>]

Hi!

I filed a gnucash bug report[1], because that's where I'm seeing the
issue, but it might be a Python problem instead.

When starting gnucash 3.3 (not in 3.2) I see lots of warnings:

Traceback (most recent call last):

AttributeError: Undefined symbol "PyOS_getsig"

The symbol is in libpython3.7.so:

# nm .../libpython3.7.so | grep getsig
0000000000162481 T PyOS_getsig
00000000001baead t signal_getsignal
00000000004e0960 d signal_getsignal__doc__

Does anyone have any ideas about that?

Missing linkage to libpython perhaps?
