Root on Windows breaks for simple loops

_ROOT Version:ROOT 6.24/00
_Platform:Windows 10
_Compiler:installation through executable


Is it just me, or does root not work properly on windows. Unfortunately I cannot use Linux on my laptop. Since years I’m trying it from time to time, hoping somebody fixes it.

Example: I create a file with a simple loop in it:

void Analyze_Data()
{
	for(int i= 0; i < 10; i++)
	{
		cout << i << endl;
	}
}

running it with “root -l Analyze_Data.C” ends with root breaking without any further information.

I can start a TCanvas, I can read data Through TTree. But loops keep breaking root.

Welcome to the ROOT Forum!
It works just fine for me:

C:\Users\bellenot\rootdev>root Analyze_Data.cxx

But it might be due to the << endl statement. Try to replace it with << "\n"

Thanks for the quick response. So I will keep looking on the configuration of my laptop and compare it with another windows machine. The “\n” did not help.

In addition to the Windows build, ROOT also works very well under WSL2 (for example running an Ubuntu distribution)
