在macOS上自制的LLVM“致命错误：'stdio.h‘文件未找到”
提问于 2019-09-01 14:24:55
- 安装LLVM
brew install llvm
- 编辑.zshrc
...
export PATH="/usr/local/opt/llvm/bin:$PATH"
export LDFLAGS="-L/usr/local/opt/llvm/lib"
export CPPFLAGS="-I/usr/local/opt/llvm/include"
...- 创建
hello.c
#include <stdio.h>
int main()
{
printf("Hello, World!");
return 0;
}- 现在，当我运行
clang -v hello.c时，我得到：

ignoring nonexistent directory "/usr/include"

End of search list.
hello.c:1:10: fatal error: 'stdio.h' file not found
#include <stdio.h>
^~~~~~~~~
1 error generated.PS。llvm的stdio.h位置：/usr/local/Cellar/llvm/8.0.1/include/c++/v1/stdio.h和/usr/local/opt/llvm ⇒ ../Cellar/llvm/8.0.1是符号链接
，有什么问题吗？

如果使用外部LLVM安装，请将它们添加到~/.bash_profile中。
LLVM_PATH="/usr/local/opt/llvm/" # or any other path
LLVM_VERSION="11.0.0"
export PATH="$LLVM_PATH:$PATH"
export SDKROOT=$(xcrun --sdk macosx --show-sdk-path)
export LD_LIBRARY_PATH="$LLVM_PATH/lib/:$LD_LIBRARY_PATH"
export DYLD_LIBRARY_PATH="$LLVM_PATH/lib/:$DYLD_LIBRARY_PATH"
export CPATH="$LLVM_PATH/lib/clang/$LLVM_VERSION/include/"
export LDFLAGS="-L$LLVM_PATH/lib"
export CPPFLAGS="-I$LLVM_PATH/include"
export CC="$LLVM_PATH/bin/clang"
export CXX="$LLVM_PATH/bin/clang++"(调整clang版本和外部llvm安装路径。)
然后运行source ~/.bash_profile

因为ignoring nonexistent directory "/usr/include"
您应该从macOS SDK headers中安装/Library/Developer/CommandLineTools/Packages/
