GCC rejects the flag outright on riscv64 ('is not supported for this
target'); oneTBB's own copy of the same file already gates it to x86,
TCM's copy does not.
…symlink cp -L produces independent files for libtcm.so, .so.1, and .so.1.5.0; patchelf only patched the bare .so, so the SONAME file the smoke test dlopens (libtcm.so.1) had no rpath and couldn't find libhwloc.so.15 sitting next to it: 'OSError: libhwloc.so.15: cannot open shared object file'.

tcmlib1.5.0Compiles Intel's Thread Composability Manager (TCM) into libtcm.so. Upstream's PyPI
tcmlibwheel is Intel's own closed-binary repackage with no sdist, so this builds the Apache-2.0 TCM source (git-subtree-merged into oneTBB) directly instead, same shape as the tbb port.No upstream CI builds this wheel; TCM has no oneTBB tag of its own, so the workflow pins the commit that introduced TCM 1.5.0 rather than a tag.
Differs from upstream
Testing
tcmGetVersion(), assert it matches the built version.License: Apache-2.0 (TCM's own LICENSE.txt); wheel also bundles HWLOC (BSD-3-Clause, its own COPYING file), since the build compiles and ships it as a runtime dependency.
Built and smoke-tested on cp312.
