Hi,

I was trying to build Zeek-8.1 RPM for Rocky 8 and 9 but it is failing at compile stage.

For context, we build Zeek RPMs for Rocky8/9 using a spec file and `rpmbuild`tool.

Zeek-8.0.3 was built with GCC-10 (`toolset-gcc-10`) on Rocky8 and standard GCC-11 on Rocky9.

With Zeek-8.1, GCC-10 gives an error on Rocky8 (`parameter packs not expanded with ‘…’`) so I am using GCC-11 (`toolset-gcc-11`).

However, both Rocky8 and 9 builds are failing

```

The build section of spec file is

```auto
%build
./configure --prefix=%{_prefix} --binary-package --enable-static-broker --disable-broker-tests --disable-btest --disable-btest-pcaps --with-python=/usr/bin/python3.11 --enable-jemalloc --disable-cpp-tests --build-type=Release
make

```

Any ideas on how to proceed with build?

Thanks

The build has progressed beyond the failure point when using `gcc-toolset-12`.

So probably Zeek-8.1 needs GCC-12 minimum to compile.

Yes exactly, zeek-8.1.0 requires at least gcc-12, see e.g., the [`CHANGES` file](https://github.com/zeek/zeek/blob/master/CHANGES#L565) or our [platform support policy](https://github.com/zeek/zeek/wiki/Zeek-Operating-System-Support-Matrix).

Thanks for pointing those links. I think such detail should also be part of release notes (like it was for 8.0).
