Compilation failure with Julia master

[maleadt]

PkgEval has been recently running into the following compilation failure when building julia#master:

│     LINK src/flisp/flisp
│ /usr/local/bin/../lib/gcc/x86_64-linux-gnu/9.1.0/../../../../x86_64-linux-gnu/bin/ld: /source/usr/lib/libuv.a(libuv_la-udp.o): in function `uv__udp_sendmsg':

I presume this is caused by JuliaLang/julia#49937, but I haven't bisected.

It's weird that Base CI isn't running into this, as PkgEval uses the package_linux v6.00 rootfs image from https://github.com/JuliaCI/rootfs-images.

Base CI uses a supported kernel. Seems you need to update glibc

[maleadt]

I'm not sure how that matters? The build is sandboxed, so glibc etc should get picked up from the package_linux image. And FWIW, the system uses the same TIG Linux used by Base CI, running kernel 5.15.

I don't know how the numbering works. Are you missing JuliaCI/rootfs-images#245?

For the record, turns out I was. Although the Artifacts.toml was updated to use the rootfs with glibc 2.17, the cached download was still using an older, incompatible version.
