Bindgen似乎无法在OSX上找到c声

问题描述

虽然我确定它做错了什么，但似乎找不到。我正在使用bindgen = "0.55.1"并尝试生成pjsip绑定，尽管在此之前问题似乎很明显。这是构建的输出：

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

我通过bindgen上的brew install llvm的{​​{1}}建议安装了clang。我已经验证了/usr/local/opt/llvm@11/lib/libclang.dylib确实存在。我怀疑该符号不存在。我是否应该安装其他版本的clang，如果是，则安装什么版本？

解决方法

好吧，我决定brew uninstall llvm作为最后的绝望之举。这似乎已经解决了问题。现在，我只是在处理链接错误，这更有意义。
