Platforms

Supported platforms

The setups tested in CI are intended to cover all platforms supported under Zeek's platform support policy. Some platforms are supported on a best effort basis.

The following configurations are continuously tested in CI, see the build configurations linked in the platform column for details:

Platform	Compiler	Zeek	Supported platform	CI	Notes
alpine-3.12	gcc-9	3.0	✅	✅
centos-stream-8	gcc-9	3.0	✅	✅
fedora-32	gcc-10	3.0	✅	main
fedora-33	gcc-10	3.0	✅	main
freebsd-11.04	clang-10	3.0	✅	✅	Zeek from distribution
freebsd-12.02	clang-10	3.0	✅	✅	Zeek from distribution
ubuntu-16	clang-11	3.0	✅	main	Compiler from LLVM upstream
ubuntu-18	clang-9	3.0	✅	main
ubuntu-20	gcc-9	3.0	✅	main
debian-9	clang-11	3.2	✅	main	Compiler from LLVM upstream
debian-10	clang-11	3.0	✅	main
debian-11	gcc-10	N/A	✅	main
MacOS Catalina	Apple Clang	3.2	✅	✅
MacOS Catalina (Homebrew)	Apple Clang	3.2	✅	main	Zeek and Spicy from Homebrew; only sanity checks
MacOS Big Sur	Apple Clang	3.2	✅	✅
MacOS Big Sur (Homebrew)	Apple Clang	3.2	✅	main	Zeek and Spicy from Homebrew; only sanity checks

But for Zeek we typically prefer distribution packages over installing directly from source; for Zeek we use prebuild pinned packages from Zeek's build service. For some setups it might still be necessary to install requirements from non-distribution sources; we e.g., install LLVM from upstream packages for Debian-like distributions or from source; the same sometimes applies to Bison, Flex, or CMake.
