我正在使用CMake在Ubuntu 16.10 x64上构建一个名为ClangEx
的简单C++ Clang工具程序。
该项目只有一个main.cpp
文件。它的内容如下:
#include "clang/Frontend/FrontendActions.h"
#include "clang/Tooling/CommonOptionsParser.h"
#include "clang/Tooling/Tooling.h"
#include "llvm/Support/CommandLine.h"
using namespace clang::tooling;
using namespace llvm;
static llvm::cl::OptionCategory MyToolCategory("my-tool options");
static cl::extrahelp CommonHelp(CommonOptionsParser::HelpMessage);
static cl::extrahelp MoreHelp("\nMore help text...");
int main(int argc, const char **argv) {
CommonOptionsParser OptionsParser(argc, argv, MyToolCategory);
ClangTool Tool(OptionsParser.getCompilations(),
OptionsParser.getSourcePathList());
return Tool.run(newFrontendActionFactory<clang::SyntaxOnlyAction>().get());
}
在使用 CMake 成功构建后,当我用它来分析一个示例 C++ 程序时,出现以下错误:
$ ./ClangEx SandwichBar.cpp --

我找到了这个bug,但安装clang-3.9
似乎并没有帮助我的情况。
如果有建议,请告诉我。谢谢。
