【问题描述】：

我正在关注Built From Source instructions 来安装grpc

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

成功

$ cd grpc

成功

$ git submodule update --init

成功

$ make

构建几个源文件后失败

我在互联网上找不到任何未解决的问题或有关此错误的任何帮助。

【解决方案1】：

如果没有嵌入式 BoringSSL，您可能会有更好的运气。尝试构建：

EMBED_OPENSSL=false make

如果您收到有关缺少软件包的错误，请确保您已安装 libssl-dev。

【解决方案2】：

编译 boringssl 时似乎出现了问题。我们使用$ git submodule 给出的版本，在撰写本文时为be2ee342d3781ddb954f91f8a7e660c6f59e87e5 third_party/boringssl (version_for_cocoapods_7.0-526-gbe2ee342)。你能自己编译boringssl吗？
