Re: [RFC PATCH 1/2] unbound: Enable the Python module(s)

[Michael Tremer <michael.tremer@ipfire.org>]

Hello,

I have the same problem.

I have built this from a non-clean build initially and everything was fine. I used that version of Unbound to write and test the code. No problems there whatsoever.

But I never managed to run a clean build. It seems that swig messes something up and I cannot tell you at all what that could be. It is not only tomli not compiling. If you comment it out and try to compile the next thing it won’t work either. I don’t know what it could break like this because the problems suddenly seem to occur in the Python standard library.

Maybe an update of Swig solves the problem? Would you like to give that a try?
