注意这里的 LLVM_INSTALL_PATH 就是你刚才安装的 llvm 路径,可以留意 message 函数输出的路径是否是预期的。 再创建一个 main.cpp 文件,内容如下 #include "clang/Tooling/Tooling.h" class ToolingASTConsumer : public clang::ASTConsumer { public: void H
-E Preprocess the C source code only 仅仅预处理C代码-D<symbol> Define <symbol> on entry to the compiler 定义 <symbol> 符号并且传入编译过程 -g Generate tables for high-level debugging 为高级别调试创建表 -I<directory> Include <directory> on the #include search path 在编译的时候包含 <directo...
而对于 Clang 的预处理器 import 与 include 指令都属于它的关键词。预处理器在处理输入口令时候主要工作为通过导入的 header 名称去查找文件的磁盘所在路径,然后进入该文件创建新的词法分析器对导入的头文件进行词法分析。如图4.7所示:编译器在遇到 #import 或者 #include 指令时,触发预处理机制查询头文件的路径,进入...

your system's path or set theLLVM_CONFIG_PATHenvironment variable. The required LLVM and Clang static libraries will be searched for in the same way as shared libraries are searched for, except theLIBCLANG_STATIC_PATHenvironment variable is used in place of theLIBCLANG_PATHenvironment variable. ...
Either ensure that llvm-config is in your PATH environment variable, or set LLVM_INSTALL_DIR to the location of your llvm installation. 31+ On Linux systems you may be able to install libclang from a package. On macOS you could use Homebrew's llvm package. ...
then xcrun will provide the full path to the macosxSDKinthe environment variableSDKROOT.Thatinturn will be used byclang(1)to automatically select thatSDKwhen compiling the test.c file. 比如,我们可以通过以下代码完成编译: 代码语言:javascript ...
Add libclang to your PATH environment variable On *Nix it’s LD_LIBRARY_PATH On Windows it’s the standard PATH Or do it in python: os.environ['PATH'] = ‘/path/to/libclang’ Copy the Clang/Python bindings from /llvm/tools/clang/bindings/python to your python installation or however ...
If you plan on using “VS 2015 x86 Native Tools Command Prompt”, please note that in the current release clang.exe is not immediately available via PATH environment variable. You’ll need to modify your environment to use clang.exe directly. ...
print(i.include.name) 通过调用get_includes()可以查看 translation unit 所包含的所有的头文件。如果读者实际进行执行的话,会发现它实际包含的头文件不止 <string>,这是因为头文件 <string> 会包含其他头文件,而这些头文件还会包好其他的头文件,compiler 需要逐个包含。
