我在 Internet 上找不到任何未解决的问题或关于此错误的任何帮助。

Answer 1

这个问题似乎是在编译 boringssl 时发生的。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？

Answer 2

如果没有嵌入式 BoringSSL，您可能会更幸运。尝试构建：

EMBED_OPENSSL=false make

如果您收到有关缺少软件包的错误消息，请确保您已安装 libssl-dev。
