Builds uamqp 1.6.11's Cython+CMake extension (the vendored azure-uamqp-c tree over system OpenSSL) for riscv64. Upstream publishes no riscv64 wheel.
…enSSL build Upstream's pyproject.toml sets [tool.cibuildwheel.linux] before-build, not before-all; CIBW_BEFORE_ALL_LINUX left it in place, so cibuildwheel ran both hooks and upstream's still-manylinux2014-targeted install_openssl.sh undid the dnf install and failed (missing perl FindBin).
…utils-c deps/azure-macro-utils-c declares cmake_minimum_required(VERSION 2.8.11), which CMake 4 (the pip-resolved build dependency) hard-refuses even though azure-uamqp-c and azure-c-shared-utility both already declare 3.5+.
CIBW_ENVIRONMENT replaces upstream's [tool.cibuildwheel.linux] environment table wholesale, dropping the CFLAGS it already carries for this: GCC 14 turns -Wincompatible-pointer-types into a hard error by default, and the Cython-generated c_uamqp.c hits it.
Several .pyx callbacks read context_pyobj.ob_refcnt directly to detect in-flight GC; that field doesn't exist on free-threaded builds' PyObject layout, so it fails identically on every arch, not just riscv64. Upstream itself ships no cp314 or cp314t wheel; cp312/cp313/cp314 all build and pass tests here.
225: CIBW_BEFORE_ALL_LINUX and CIBW_BEFORE_BUILD_LINUX are separate hooks; overriding the one upstream doesn't use lets both run. 226: GCC 14 defaults -Wincompatible-pointer-types to a hard error for C code, and CIBW_ENVIRONMENT (gotcha 107) silently drops any CFLAGS fix upstream already carries for it. 227: PyObject internals (ob_refcnt) accessed directly break free-threaded builds identically on every arch -- trim the matrix, don't patch.

uamqp1.6.11Compiles uamqp's Cython extension over the vendored
azure-uamqp-cAMQP 1.0 C library (statically built via CMake) linked against OpenSSL. Upstream publishes no riscv64 wheel.Mirrors the
ManyLinuxjob of upstream'sclient.yml.Differs from upstream
dnf-installed OpenSSL instead of building OpenSSL 3.0.15 from source - only needed for manylinux2014's ancient one.samples/- needs live Event Hub/Service Bus credentials; upstream itself gates that job to its internal (non-public) pipeline.Matrix: cp312/cp313/cp314, no cp314t - several
.pyxcallbacks readob_refcntdirectly, which doesn't exist on free-threaded builds'PyObjectlayout; upstream itself ships no cp314 or cp314t wheel either.Testing
tests/, which exercises the builtc_uamqpextension directly; same as upstream's public path.License: Wheel bundles the vendored
azure-uamqp-ctree (MIT) and dynamically links OpenSSL (Apache-2.0); upstream ships neither licence text in the wheel, so the build adds both.Built on cp312; 46 passed.
