How is this different than #421 ??

[tjcw]

This PR is different from #421 . This one introduces support for openxl and xlclang tool chains on AIX . #421 works around a deficiency in AIX directory name support.

I see the test fails with messages

src/tools/openxl.jam has documentation but is not included anywhere, uses tags: doc
src/tools/xlclang.jam has documentation but is not included anywhere, uses tags: doc

Please can someone tell me how to link these into the documentation system to get the tests to pass. Thanks !

It means they need to get added to the reference doc in the right section.. https://github.com/bfgroup/b2/blob/main/doc/src/reference.adoc

I have closed #421 as not being required. I think this one is now ready for review and removing the 'draft' label.

I have added the files as required

So is the failing check related to the change?
You should be able to look at the patch and verify that it only changes things for xlclang and openxl tool chains , i.e. it is only an AIX change and you do not have any AIX tests.

Something caused a test to run for an hour until cancelled, but I don't think my change did it.

What next ?

It's a recurring problem that I haven't been able to track down (as it only happens in CI). I'm rerunning the checks.

What next ?

Here's the thing.. I'm unhappy with yet more toolsets for the IBM compilers. As they are all almost identical. Ideally we would have just one toolset that handles the variation internally. I started sketching out such a toolset a few days ago. But it's going to take some time for me to get it sufficiently complete to test (as I have ISO WG21 meetings this week). Would you be able to test and help out further tweaking of such a combined toolset?

[tjcw]

Yes, I can help with that. Just tell me which repo to clone and what command to run.

[tjcw]

I will need to ask my manager whether I can run your code on my IBM owned AIX box. If the answer is no, then the boost project could buy the usage you need in the IBM cloud here https://cloud.ibm.com/power/overview . I think there are also possibilities on university-owned machines but I don't have a reference to hand.
