CERN ROOT framework segmentation fault with visual C-CodePudding

I am trying to use CERN's ROOT framework inside a Visual C project.

I built it from sources using the following commands (https://root.cern/releases/release-62606/):

cmake -G"Visual Studio 17 2022" -A x64 -Thost=x64 -DCMAKE_INSTALL_PREFIX=..\install_dir ..\root_src

cmake --build . --config Debug --target install

git clone --branch latest-stable --depth=1 https://github.com/root-project/root.git root_src

I then tried to build an example to test if my setup worked.

#include "TF1.h"
#include "TApplication.h"
#include "TCanvas.h"
#include "TRootCanvas.h"

int main(int argc, char** argv)
{
    TApplication app("app", &argc, argv); // Seg fault happens with this line
    TCanvas* c = new TCanvas("c", "Something", 0, 0, 800, 600);
    TF1* f1 = new TF1("f1", "sin(x)", -5, 5);
    f1->SetLineColor(kBlue   1);
    f1->SetTitle("My graph;x; sin(x)");
    f1->Draw();
    c->Modified(); c->Update();
    TRootCanvas* rc = (TRootCanvas*)c->GetCanvasImp();
    rc->Connect("CloseWindow()", "TApplication", gApplication, "Terminate()");
    app.Run();
    return 0;
}

When I build this code and run it, I get a segmentation fault.

The program '[28120] RootTest.exe' has exited with code 0 (0x0).

Visual Studio tells me that the error comes from TWinNTSystem.cxx line 1017

while (buf[0] && GetFileAttributes(check_path.Data()) == INVALID_FILE_ATTRIBUTES) {

I use /sdl-, /permissive and /std=c 17.

Do you have any idea why I am having this segmentation fault ?

CodePudding user response：

%ROOTSYS% must be set else ROOT won't be able to find %ROOTSYS/etc directory.

This can be achieved by running thisroot.bat.
