I would like to change my clang tool's include path according to input. When I run the below code on a sample test file I have a compilation error "header not found".
#include "clang/Frontend/FrontendActions.h"
#include "clang/Tooling/CommonOptionsParser.h"
#include "clang/Tooling/Tooling.h"
// Declares llvm::cl::extrahelp.
#include "llvm/Support/CommandLine.h"
using namespace clang::tooling;
using namespace llvm;
static llvm::cl::OptionCategory MyToolCategory("my-tool options");
int main(int argc , char** argv) {
int argc_ = 5;
const char **argv_ = new const char*[5];
std::vector<std::string> Sources;
Sources.push_back("path\\to\\Testfile.cpp");
argv_[0] = argv[0];
argv_[1] = &Sources[0][0];
argv_[2] = "--";
argv_[3] = "c++";
argv_[4] = "-I\"path\\to\\external\\lib\\directory\"";
CommonOptionsParser OptionsParser(argc_, argv_, MyToolCategory);
// run the Clang Tool, creating a new FrontendAction (explained below)
ClangTool Tool(OptionsParser.getCompilations(), Sources);
int result = Tool.run(newFrontendActionFactory<clang::SyntaxOnlyAction>().get());
system("pause");
return result;
}
