Hello！I want to know how to run root on jetbrains clion?

[MrDoubleU]

I have a project named ROOTTest and the project has a cpp file named main.cpp.

here are some environment variables:
ROOT_SYS: /opt/root
ROOT_INCLUDE_DIRS: /opt/root/include
ROOT_LIBRARIES: /opt/root/lib

i edit CMakeLists in CLion like this:

cmake_minimum_required(VERSION 3.6)#原始
project(ROOTTest)#原始

set(CMAKE_CXX_STANDARD 11)#原始


list(APPEND CMAKE_PREFIX_PATH  $ENV{ROOTSYS})  
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} $ENV{ROOT_SYS}/etc/cmake)
find_package(ROOT REQUIRED COMPONENTS RIO Net)
include_directories($ENV{ROOT_INCLUDE_DIRS})
link_directories(/opt/builddir/lib)


set(SOURCE_FILES main.cpp)#原始

add_executable(ROOTTest ${SOURCE_FILES})#原始
target_link_libraries(ROOTTest -lCore -lRIO -lNet -lHist -lGraf -lGraf3d -lGpad -lTree -lRint -lPostscript -lMatrix -lPhysics -lMathCore -lThread -pthread -lm -ldl -rdynamic
)

main.cpp is like this:

#include <iostream>
#include <stdlib.h>
#include "TTree.h"
#include "TROOT.h"
#include "TRandom.h"
#include "TFile.h"
#include "TLeaf.h"
#include "TMessage.h"
#include "TBrowser.h"
#include "TTreeReader.h"
#include "TTreeReaderValue.h"
#include "TBuffer.h"



using namespace std;

int main(){
    new TBrowser();
    return 0;
}

but the result is like this:

why the program can’t run?

Hi,

The code you posted (only main()) doesn’t correspond to the crash (main() calls hello()). And as the crash happens in hello() you’ve skipped the relevant part.

Axel.

[MrDoubleU]

Hello！The error is like this. I just can’t use TBrowser in main function. The other functions are OK

[MrDoubleU]

I change the main function like this:

int main() {
    
    TApplication *a = new TApplication("a", 0, 0);
    TBrowser tBrowser;

    return 0;
}

But it only appeared for few seconds and then disappeard.

[Axel]

Questions like these are why we recommend not to build your own program, but use your code from inside ROOT.

Do you really need to build your own program?

(The reason is that you don’t create an event loop; TApplication::Run() does that.)

Axel.

[MrDoubleU]

Thank you very much! The problem is solved.
