使用 g++ 12 或 13 的 BoringSSL：失败-解网

问：

在 Debian 测试中使用高于 g++ 的 gcc 编译 BoringSSL 失败，并显示：

步骤：

git clone https://github.com/google/boringssl.git
cd boringssl
cmake -DCMAKE_CXX_COMPILER=g++-12 -DCMAKE_BUILD_TYPE=Release -B build -GNinja
ninja -C build

适用于 g++-11。没有尝试使用 gcc-10，因为我不在乎。

知道如何让它与 g++-12 或 13 一起使用吗？

谢谢

对于那些感兴趣的人，这是他们的错误跟踪器上的问题：

C++ 无聊SSL

使其工作的唯一方法是关闭警告消息。在没有查看源代码的情况下，它很可能是误报。这些来自最新版本的 gcc 的警告消息通常是误报，并且正在让很多人在完全符合犹太教的代码上发球。你不太可能在 Stackoverflow 上找到开发人员，他们有自己的邮件列表。他们需要意识到 gcc 正在“下雨”他们的代码，并解决它。-Wdangling-pointer

你是说 chromium-dev 谷歌组？

答： 暂无答案

上一个：设置了 N 位的跳转值？

下一个：Mmap ：失败并显示MAP_SYNC
