Errors and a hang rebuilding

Installing

Hi Jan

I routinely rebuild from source of Ubuntu without problems but today errors and a hang.

Regards

Mike

Thanks for reporting. Both are fixed. I’m trying to clean the 134 open issues. Closed about half and clearly fixed one wrong :frowning: Builds and tests again for me.

I surely do. A bit of programming is a good distraction though :slight_smile: Bad news is that more surgery is needed and it is more serious than hoped for due to complications :frowning:

Incidentally, the http proxy tests fail due to concurrency issues with test port allocation. This was recently improved a little, but there are still opportunities for these tests to fail. Just ignore them …
