how to link libclang and libtooling to QT project

jdenv

I want to build AST using clang library in my project.
In my main.cpp file I have following:

#include <clang/Tooling/Tooling.h>
#include <clang/AST/ASTConsumer.h>
#include <clang/AST/RecursiveASTVisitor.h>

I added this to my .pro file:

INCLUDEPATH += /home/jdenv/rep/libs/llvm-project/install/include/
INCLUDEPATH += /home/jdenv/rep/libs/llvm-project/install/include/clang/
INCLUDEPATH += /home/jdenv/rep/libs/llvm-project/install/include/llvm/

LIBS += -L /home/jdenv/rep/libs/llvm-project/install/lib -lclang
LIBS += /home/jdenv/rep/libs/llvm-project/install/lib/libLLVMSupport.so
LIBS += /home/jdenv/rep/libs/llvm-project/install/lib/libclangTooling.so

autocompletion and code highlighting in editor work normal, but when I try to build, I get an error:
![7f7890aa-4e3f-4dd5-8a4f-089645d9bc97-изображение.png](https://ddgobkiprc33d.cloudfront.net/b83810f6-abef-428f-9153-60364d6bea88.png) 

What should I do? I've never linked libraries before so I would be very grateful for your help

seems like something wrong with the image, so the error i get is
/home/jdenv/rep/libs/llvm-project/install/lib/../lib/libclangFrontend.so.22.0git: error adding symbols: DSO missing from command line

This is wrong. Should be:

LIBS+=-L/home/jdenv/rep/libs/llvm-project/install/lib -lclang
LIBS+=-L/home/jdenv/rep/libs/llvm-project/install/lib -lLLVMSupport
LIBS+=-L/home/jdenv/rep/libs/llvm-project/install/lib -lclangTooling

The picture with the error you posted is not visible. Please post errors as text.

@jsulm I've edited LIBS like you said, but I still get following errors:
main.o: undefined reference to symbol '_ZN5clang14FrontendAction13EndSourceFileEv'
/home/jdenv/rep/libs/llvm-project/install/lib/../lib/libclangFrontend.so.22.0git: error adding symbols: DSO missing from command line

Hi,

Are you sure you are linking all the required libraries ?

Looks like one of the clang libraries is missing
