README.md

nothing to be seen here yet. LEAVE

But if you are curious (probably not), read ahead

Dependencies

Tested toolchains

  • LLVM 18.1.7
  • GCC 14.1.0

In theory, any toolchain supporting at least the c++23 standard should work. I am using LLVM's clang and libcxx as the primary toolchain.

Static libraries

Name Version Required? Purpose
catch2 >= 3.4 no for tests

This goes without saying but using a different toolchain to compile these libraries before linking probably won't work.
