You need to make sure that system maxima < 5.48 is not accepted, because the *pcprntd* change is not compatible with it. That requires a check in build/pkgs/maxima/spkg-configure.m4 at least, maybe somewhere else.

And we also need to decide what to do with system 5.48. Functionally it should work, but some tests will fail with different output. So we either

  • Fix the tests to pass with 5.48 too
  • Disallow system 5.48 (5.49 was released in december, so probably too soon)
  • Allow system 5.48 and ignore the test failures

I think we just ignore this. Because in fact, it is not mathematically wrong, just the expressions are different but they are equal

It seems the bug of increment docker build. after we build new docker image, this will be fixed.

Sorry, i figured this out later on but missed the ones in this early PR. I'll go through this file and remove the remaining inline tags.

You still haven't addressed #41879 (comment). According to https://repology.org/project/maxima/versions there aren't many distros shipping 5.48, so maybe we can allow that with a few broken tests (although I'm not 100% happy about it), but you definitely need to exclude < 5.48.

In any case, I can't approve this myself, it's 90% my code.

So we block <5.48?

It seems meson.build missing ecl's path caused docker build failed. I have editted it. @tobiasdiez

What exactly is the error that needs compilation with the ecl include dir now?

Increase docker build seems will incorrect, if we update ecl for different path include (before using system's ecl, now using sage's ecl). I think we just needs a warning about this. If the user do not counter the increase build for different path of ecl, they do not encounter this problem.

The main problem is in test-long

That looks more like a CI bug/shortcoming to me. If the CI / linux runs are okay, then I don't see any need to fix the test-long. Or is there any realistic scenario where users would run into the same issue?

If you first compile with system's ecl, then second increasely compile with sage's ecl (change path). then it will cause problem.

and I think it is a much special case. We just add a warning if we can not find ecl_config

This seems also trigger on ecl 24.5.10. It is not a problem caused by ecl 26.3.27

I never saw this with 24.5.10. I'm seeing it occasionally on 26.3.27.

Here's another issue with 26.3.27 that I never saw before: https://github.com/void-linux/void-packages/actions/runs/24376377943/job/71190688685?pr=59932#step:7:36197

Upgrade to Maxima 5.49 and ECL 26.3.27
8844bed 
- Upgrade Maxima to 5.49 and ECL to 26.3.27
- Enhance robustness of *maxima-objdir* directory creation in maxima_lib.py
- Add warnings for fallback to ecl_lib in meson.build to improve ECL build reliability
- Format meson.build
- Align ECL first_env to 65536 bytes to fix flaky mprotect EINVAL crash
  (ECL 26.3.27 changed the main thread env from mmap-allocated to a static
  struct; mprotect() requires page alignment, which mmap() guaranteed but
  a static variable does not)
