Question

I am following the Built From Source instructions to install grpc

$ git clone -b $(curl -L https://grpc.io/release) https://github.com/grpc/grpc

success

$ cd grpc

success

$ git submodule update --init

success

$ make

fails after building a few source files

Answer 1

The problem seems to happen while compiling boringssl . We use the version given by $ git submodule , which at the time of this writing is be2ee342d3781ddb954f91f8a7e660c6f59e87e5 third_party/boringssl (version_for_cocoapods_7.0-526-gbe2ee342) . Are you able to compile boringssl on its own?

Answer 2

You might have better luck without the embedded BoringSSL. Try building with:

EMBED_OPENSSL=false make

If you get errors about missing packages, make sure you have libssl-dev installed.
