gRPC build with gcc on macOS fails because of boringssl-with-basel

[Dan Cohen]

Hello,

I need to build gRPC with gcc on mac. When trying to do so, boringssl-with-basel compilation fails with:
[ 12%] Building ASM object third_party/boringssl-with-bazel/CMakeFiles/crypto.dir/apple-aarch64/crypto/chacha/chacha-armv8-apple.S.o
clang: error: unsupported option '--noexecstack'
make[2]: *** [third_party/boringssl-with-bazel/CMakeFiles/crypto.dir/apple-aarch64/crypto/chacha/chacha-armv8-apple.S.o] Error 1
make[1]: *** [third_party/boringssl-with-bazel/CMakeFiles/crypto.dir/all] Error 2

This is how my cmake configuration of gRPC looks like:

(running from grpc/cmake/):

cmake -B release -DCMAKE_EXE_LINKER_FLAGS="-ld_classic" -DCMAKE_BUILD_TYPE=Release -DgRPC_INSTALL=ON -DgRPC_ABSL_PROVIDER=package \
-DgRPC_PROTOBUF_PROVIDER=package -DCMAKE_CXX_STANDARD=17 -DCMAKE_CXX_COMPILER=/opt/homebrew/bin/g++-13 \
-DCMAKE_C_COMPILER=/opt/homebrew/bin/gcc-13 -DCMAKE_INSTALL_PREFIX=../../install -DCMAKE_PREFIX_PATH=../../install -S ../

I've tried several things, including cloning the boringssl-with-basel in a separate directory and building it locally (not as part of grpc) but this also fails with different reasons.

Is there a standard way to build gRPC on macOs with gcc? or disable the offending package from boringssl build?

Thanks,

Dan

Do you have `openssl` installed?

If that's the case, you don't need boringssl, you can simply specify `-DgRPC_SSL_PROVIDER="package"` to use the installed openssl version.

See https://github.com/grpc/grpc/blob/master/cmake/ssl.cmake and https://cmake.org/cmake/help/v3.6/module/FindOpenSSL.html for more information.
