[lldb-dev] Problem with Ubuntu 18.04: Python LLDB not working

[Julien Marrec via lldb-dev]

Hello,

I had a few machines on 16.04 with LLDB 8 an all was going nicely.
I have ported a bunch to 18.04, and I have the same problem on all of them:
the `script` command in lldb doesn't work, and so my custom formatters for
C++ aren't working.
I have tried LLDB 8, LLDB 9, and LLDB 10, to no avail.

Recently, pruned everything related to lldb/llvm then installed fresh:

I have tried to read the archive (which isn't searchable as far as I can
tell) and went a few months back, found a couple of posts including one
that linked to https://bugs.llvm.org/show_bug.cgi?id=43830 but this should
be in 9.0.1 too...

I'm at a loss, and this is hindering my debugging since I'm missing my
usual formatters (such as formatters for Qt etc).

Can someone help please?

Thank you,
