gRPC安裝在“ make”位置失敗

Question

我正在按照“從源構建” 說明安裝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

構建一些源文件后失敗

我在互聯網上找不到任何未解決的問題或有關此錯誤的任何幫助。

Answer 1

該問題似乎是在編譯boringssl時發生的。 我們使用$ git submodule給定的版本，在撰寫本文時，該版本為be2ee342d3781ddb954f91f8a7e660c6f59e87e5 third_party/boringssl (version_for_cocoapods_7.0-526-gbe2ee342) 。 您能夠自行編譯boringssl嗎？

Answer 2

如果沒有嵌入式BoringSSL，您可能會有更好的運氣。 嘗試使用：

EMBED_OPENSSL=false make

如果遇到有關缺少軟件包的錯誤，請確保已安裝libssl-dev 。
