Dear all

trying to build the milvus_cli on >= rhel9.4 on power.
yes conda builds for an older version, but i need milvus version2 and >= python3.11
pip fails with the grpcio wheel build. Uses boringssl
2025-11-12T17:09:14,369   third_party/boringssl-with-bazel/src/include/openssl/target.h:74:2: error: #error "Unknown target CPU"
2025-11-12T17:09:14,370      74 | #error "Unknown target CPU"
switch to openssl
DgRPC_SSL_PROVIDER=openssl
GRPC_PYTHON_BUILD_SYSTEM_OPENSSL=true
gets rid of the Unknown target CPU error but eventually fails the build.

whether i use 
pip install torch  seqeval accelerate pymilvus sentence-transformers transformers langchain  numPy
or just
pip install --no-cache-dir --force-reinstall milvus_cli
in the VM or in a venv. still fails,

error below
Successfully built pandas numpy
Failed to build grpcio
error: failed-wheel-build-for-install

× Failed to build installable wheels for some pyproject.toml based projects
╰─> grpcio

if i force grpcio reinstall, no cache, it builds on its own , the subsequent build of milvus_cli also works , but execution of milvus_cli is broken.
 
Has anyone built this successfully on linux on power for milvus v2 ?
Can anyone please help in this process?

Thanks

Ian
