Same here

That include has been there for many releases. I don't understand what could have changed.
Does /home/cc/venv/lib64/python3.15t/site-packages/pybind11/include/pybind11/buffer_info.h exist?

[clin1234]

Yes:

It's a complete mystery to me. If any Python experts can figure out what's wrong I'm happy to apply a patch.

[Vegoo89]

Newest version also fails to build inside RHEL7 container with conda and python 3.9 for me.
I can't copy exact error due to corporate restrictions (can't log into GitHub), but few last lines are:

      _re2.cc:15:10: fatal error: absl/strings/string_view.h: No such file or directory
      #include "absl/strings/string_view.h"
                      ^~~~~~~~~~~~~~~~~~~~~~~~
      compilation terminated.
      error: command '/usr/bin/gcc' failed with exit code 1
      [end of output]

Previous version works fine

Edit: Ok for me problem may be missing whl for python 3.9 that has not been built in this release anymore. I see its present in previous release but not in this one.

Probably because 3.9 support was dropped since it's EOL: 11c643a
