只编译一个最小的"bb.cpp"文件.代码如下:

#include <常用>

#include "clang/AST/ASTConsumer.h"
#include "clang/AST/RecursiveASTVisitor.h"
#include "clang/Frontend/CompilerInstance.h"
#include "clang/Frontend/FrontendAction.h"
#include "clang/Tooling/Tooling.h"

using namespace clang;
class FindNamedClassVisitor
  : public RecursiveASTVisitor<FindNamedClassVisitor> {
public:
  explicit FindNamedClassVisitor(ASTContext *Context)
    : Context(Context) {}
  bool VisitCXXRecordDecl(CXXRecordDecl *Declaration) {
    if (Declaration->getQualifiedNameAsString() == "n::m::C") {
      FullSourceLoc FullLocation = Context->getFullLoc(Declaration->getBeginLoc());
      if (FullLocation.isValid())
        llvm::outs() << "Found declaration at "
     << FullLocation.getSpellingLineNumber() << ":"
     << FullLocation.getSpellingColumnNumber() << "
";
    }
    return true;
  }
private:
  ASTContext *Context;
};
class FindNamedClassConsumer : public clang::ASTConsumer {
public:
  explicit FindNamedClassConsumer(ASTContext *Context)
    : Visitor(Context) {}
  virtual void HandleTranslationUnit(clang::ASTContext &Context) {
    Visitor.TraverseDecl(Context.getTranslationUnitDecl());
  }
private:
  FindNamedClassVisitor Visitor;
};
class FindNamedClassAction : public clang::ASTFrontendAction {
public:
  virtual std::unique_ptr<clang::ASTConsumer> CreateASTConsumer(
    clang::CompilerInstance &Compiler, llvm::StringRef InFile) {
    return std::make_unique<FindNamedClassConsumer>(&Compiler.getASTContext());
  }
};
int main() {
    串 a{"aa.cpp"},b;
    至冲(a,b);

    clang::tooling::runToolOnCode(std::make_unique<FindNamedClassAction>(), b);
}

这里,还需要编译命令.json.
