1.83.1: test suite fails in `ioformats_reg` unit about leptonica HOT 7 CLOSED

Thank you for reporting this issue.

You skipped 25 tests because you don't have gnuplot, but that should not be a problem.

Are you running the test with make -jx check where x > 1? If so, please re-run with just make check, and that should fix the tests, which are likely due to a race condition.

Otherwise, there are a couple of puzzles here.

(1) The jp2k tests failed for RGB and 16 bpp, based on the error messages. However, they returned success! Also, why is it that the written jp2k files can't be read?

(2) pnm is failing for two 32-bit images that were derived from 1 and 2 spp with alpha. This is very strange, because pnm I/O does not depend on any external imaging library.

In any event, I will modify ioFormatTestj() to allow retrieval of the output written files, which will simplify any problem diagnosis.

As for updating the release to 1.84, I expect to do that in the next month, so that we have a new stable version for Ubuntu 24.04

Yes I'm running with -j48.
OK will try .. so it looks like it is only parallelisation issue 🤔
Good to know 👍

Just tested that with -j1 test suite is OK.

Great. Thanks for clarifying.

Is this parallelisation issue is already solved or still not? 🤔

It continues and I'm not concerned about it. I will make a note in the README.html that the test should be done for j1.

As long as you are using automake I think that you shuld have look on
