pmix-sys

pmix-sys exposes the PMIx API through bindgen. It either uses an existing installation (set DEP_PMIX_ROOT) or builds the bundled openpmix-src Autotools tree together with optional bundled hwloc/libevent.

Features

  • vendored triggers the openpmix-src build plus vendored-hwloc/vendored-libevent so the entire stack is self-contained.
  • vendored-hwloc / vendored-libevent vendor just hwloc or libevent (via the bundled hwlocality-sys/libevent-sys features), while still vendoring PMIx itself. Set HWLOC_DIR / LIBEVENT_DIR to a system install prefix for whichever one you leave unvendored (e.g. HWLOC_DIR=$(brew --prefix hwloc) cargo build --features vendored-libevent). This is the escape hatch for macOS, where hwlocality's vendored autotools build fails.
  • Leave vendored off to link against a system PMIx install; DEP_PMIX_ROOT must point to that tree so the build script can forward include and lib paths.
