Pull request overview

Updates native build configuration to improve compatibility with Haiku when building dotnet/runtime native components, primarily by feature-detecting pthread robust-mutex APIs and adjusting Haiku linker behavior in CMake.

Changes:

Add CMake feature checks for pthread_mutex_consistent and pthread_mutexattr_setrobust, and expose them via pal_config.h.
Conditionally compile robust-mutex initialization and recovery paths in pal_crossprocessmutex.c based on those feature macros.
Adjust Haiku CMake linker-group settings as a workaround for missing upstream CMake support.

No problem, I can take a look after this round of PRs are in. I was under the impression that the Haiku’s llvm port is in progress. We can also use llvm’s libc++ (instead of GNU’s libstdc++) these days using -p: TargetCxxStandardLibrary=libc++ etc. to keep build solely rely on llvm-toolchain.

@jkoritzinsky, this one. is also ready. (needed to actually build runtime repo for Haiku)

This contains the missing configuration updates required to build the native component for Haiku with the latest .NET source.

trungnt2910 · 2026-04-28T10:20:33Z

For documentation purposes:

Haiku does not support robust mutexes: https://dev.haiku-os.org/ticket/20033
There is a WIP attempt to implement this API: https://review.haiku-os.org/c/haiku/+/10707, but it does not work due to lack of kernel-mode support for unlocking mutexes when the owner process dies.

Seems like the priority is runtime code size, not portability. Reverted the cross-process mutex implementation choice to a OS-based list instead of a dynamic configure-time check. Also tell the managed counterpart that Haiku does not support this feature to prevent future issues.
