<pre>
This is my code:
```cpp
#include "clang/Driver/Options.h"
#include "clang/AST/AST.h"
#include "clang/AST/ASTContext.h"
#include "clang/AST/ASTConsumer.h"
#include "clang/AST/RecursiveASTVisitor.h"
#include "clang/Frontend/ASTConsumers.h"
#include "clang/Frontend/FrontendActions.h"
#include "clang/Frontend/CompilerInstance.h"
#include "clang/Tooling/CommonOptionsParser.h"
#include "clang/Tooling/Tooling.h"
#include "clang/Rewrite/Core/Rewriter.h"
using namespace std;
using namespace clang;
using namespace clang::driver;
using namespace clang::tooling;
using namespace llvm;
Rewriter rewriter;
int numFunctions = 0;
int main(int argc, const char **argv) {
llvm::Expected<CommonOptionsParser> op = CommonOptionsParser::create(argc, argv, llvm::cl::getGeneralCategory());
}
```
this is my clang version (built from source):
```shell
~/Projects/compiler/llvm-project-llvmorg-14.0.1/build/bin/clang -v
clang version 14.0.1
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir: ~/Projects/compiler/llvm-project-llvmorg-14.0.1/build/bin
Found candidate GCC installation: /usr/lib/gcc/x86_64-linux-gnu/10

Selected GCC installation: /usr/lib/gcc/x86_64-linux-gnu/11
Candidate multilib: .;@m64
Selected multilib: .;@m64
```
and this is my compile command:
```shell
~/Projects/compiler/llvm-project-llvmorg-14.0.1/build/bin/clang -L/usr/lib -lclangAST -lclangBasic -lclangFrontend -lclangSerialization -lclangTooling -lclangFrontend -lclangSerialization -lclangDriver -lclangTooling -lclangParse -lclangSema -lclangAnalysis -lclangRewriteFrontend -lclangRewrite -lclangEdit -lclangLex -lclangBasic test.cpp -o test
```
All libraries are located in `/usr/lib`
this is my compile result:

why? what's wrong? I'm so confused and I hope you can help!
thank you!
