Serpent OS seeks to be correct wherever possible, in the most pragmatic sense. Some upstream projects that we use, are incompatible with Clang/Musl/Both for a variety of reasons, not always limited to non-compliance. In some cases, the toolchain simply doesn't provide a viable alternative to the functionality being used.
In these cases, we'll be using libwildebeest. It will provide a very
small overlay library with the missing definitions and functions to get
the software to build and run successfully.
Additionally we'll be able to track so-called 'GNUisms' in Serpent OS by
checking any package that build-depends upon libwildebeest and work with
various upstreams to eradicate the need for this software.
As such there is no promise of ABI stability, and static linking will be preferred.
Our goal is simple, centralise extensive patchwork that seeks to recreate libgcc_s/glibc compatibility in each program, instead of patching those into every single software package.
List of functions/APIs we definitely need to bolt on. This list will be growing over time as we encounter more areas of incompatibility.
