编译Rust的项目时候出现了错误:

error: failed to run custom build command for croaring-sys v0.3.7
process didn't exit successfully: /Users/.../grin/target/release/build/croaring-sys-20d6d5c35e3a436a/build-script-build (exit code: 101)

关键的错误信息是:

error: unknown type name 'uint64_t' cargo:warning= uint64_t ri resident_size;
复制代码

原因是升级了Mac系统之后 C++ .h 不正确造成的。 解决的方式,是删除clang相关的编译环境,并重新安装,首先删除头文件:

rm -rf /usr/local/include/*

再卸载LLVM相关的工具链

brew uninstall llvm

最后需要卸载掉Xcode命令行工具:

rm -rf /Library/Developer/CommandLineTools

卸载掉clang相关工具之后,再重新安装。 安装Xcode命令行工具:

xcode-select --install

安装llvm

brew install --with-toolchain llvm

重新编译正常。
