Bindgen似乎无法在OSX上找到clang

Question

虽然我确定我做错了什么，但我似乎找不到它。我正在使用bindgen = "0.55.1"并尝试生成pjsip绑定，尽管这个问题似乎早在此之前就出现了。以下是构建的输出：

error: failed to run custom build command for `test-pjsip v0.1.0 (/Users/bruce/Projects/rust/examples/test-pjsip)`

Caused by:

我通过bindgen推荐的brew install llvm在macOS上安装了clang。我已经验证了/usr/local/opt/llvm@11/lib/libclang.dylib确实存在。我怀疑符号不存在就是问题所在。我应该安装一个不同的(旧的) clang版本吗?如果是，是什么版本？

好吧，我决定brew uninstall llvm作为最后一次绝望的行为。这似乎已经解决了这个问题。现在，我只处理链接错误，这就更有意义了。
