Hey folks, a little status update here. First, huge thanks are due to
nobodino for helping to shake out packages that weren't building from source.
With all those fixes in place (plus a few more), we have tested and found that
everything in the tree compiles cleanly against glibc-2.32. So, the plan is to
have another mass rebuild soon against that. Although the ABI didn't
technically change, I've heard that libpthread may not be 100% compatible in
some corner cases, so we'll err on the side of caution. Hopefully we can get a
little testing done on the recompiled system and then go through it all again
at the beginning of next month when glibc-2.33 is released. Other than that,
how's Mesa working these days? If there are still issues that are resolved by
dropping back to the previous branch, let's try to figure those out. I'd rather
not revert Mesa unless there's no other choice. I'm hoping that the (probably
unrelated) issues with Intel video hardware will be helped by today's
xorg-server patch that uses the modesetting driver with newer chipsets. Please
report any improvement on the LQ thread.
Beta approaches. :-)
