Re: [orca-list] orca and liblouis

[<prayner unimelb edu au>]

I had a problem that might be related. I think it arose from a mixture of
locally built orca (cloned from gitlab) and a distribution-installed
liblouis. Orca wasn't finding the braille table I wanted. You might be
able to check on where orca is searching for the tables. I would use
strace for this e.g.
<https://serverfault.com/questions/219323/monitor-open-process-files-on-linux-real-time>
but that's probably pretty old school.
