Cannot build on IBM s390x architecture because gRPC builds failed.

[hv0905]

When building the docker image on IBM LinuxOne, an error encountered:

According to BoringSSL, it seems that s390x is not a supported architecture.

Are there any way to solve this problem or workaround it? Any help would be thanked!

After investigating, this problem can be solved by using openSSL library provided by system, instead of Google's boringSSL, Below is the dockerfile to build gRPC I used in my project:

RUN apt-get update && apt-get install ca-certificates curl build-essential ninja-build git cmake libspdlog-dev libssl-dev openssl -y --no-install-recommends && \
    rm -rf /var/lib/apt/lists/*

ENV GRPC_RELEASE_TAG="v1.59.1"

RUN git clone -b $GRPC_RELEASE_TAG https://github.com/grpc/grpc \
    && cd grpc && git submodule init && git submodule deinit third_party/boringssl-with-bazel && git submodule update \
    && mkdir -p cmake/build && cd cmake/build && cmake -G Ninja -DCMAKE_BUILD_TYPE=Release -DgRPC_SSL_PROVIDER=package ../.. \
    && ninja && ninja install && cd / \
    && rm -rf grpc

Hope this would help.
