Hi all,
Here is once again freshly updated Ruby. The changes are available here:
https://src.fedoraproject.org/rpms/ruby/pull-request/70
and you can find the scratch build in Koji:
https://koji.fedoraproject.org/koji/taskinfo?taskID=54978639
From the notable changes, there is ongoing effort to gemify StdLib.
As always, please let me know if you encounter any issues with the package.
It seems I'm still not able to build gems like eventmachine:
I wonder what precisely is "gems like eventmachine"

Error I'm getting is ``` make: I.: No such file or directory ``` note the missing -
I think the issue is not in the `-` but in what is missing prior it. If you see this line, isn't there something strange?

If you checked the Makefile, these are the corresponding lines:

So one of the reasons is that we don't have C++ compiler available during Ruby build and therefore there are not stored the appropriate values into RbConfig (I mildly remember, that there could have been also patch to remove the need for C++ or it was reported somewhere, but I don't remember more details).
The other reason is that somebody changed something somewhere and apparently something relies on it. The question is what. I would appreciate if somebody helped me to understand what have changed.
One could also expect, that the extconf.rb + mkmf would include check for compiler availability and let the compilation fail earlier, but this is not the case unfortunately. So if somebody could investigate, if eventmachine and possibly also other package could check on compiler availability, that could help to prevent non-obvious issues like this.
Checking the mkmf.log, it is also interesting to see, that most of the configuration check are done using `gcc`, while there also other checks:
~~~

~~~
They are missing the `gcc` on the beginning and they appears to be silently ignored. But these corresponds to:
https://github.com/eventmachine/eventmachine/blob/b50c135dfdd4e7b20c8e0b7ce1...
https://github.com/eventmachine/eventmachine/blob/b50c135dfdd4e7b20c8e0b7ce1...
So these are somehow expected to fail, but they should probably fail in different way.

( The same gem succeeds all other Fedoras: https://copr.fedorainfracloud.org/coprs/pvalena/rubygems/build/1767304/ )

Any idea what is the state of vagrant w.r.t Ruby 3.0? I know upstream struggled quite a bit with 2.7 already.
Cheers,
Dan
Hello Dan,
that's a good point!
Let me investigate / check in my vagrant-testing COPR repo, similarly to what I've done in rubygems-testing repo (for which I'll run the previuosly failed builds as well).
https://copr.fedorainfracloud.org/coprs/pvalena/rubygems-testing/ https://copr.fedorainfracloud.org/coprs/pvalena/vagrant-testing/
I'll write a summary here once some the builds finish (~1week).
