1.) i just now re-installed:
root_v6.30.06.win64.vc17.exe (127Mb)
2.) and I have:
Microsoft Visual Studio Community 2022
Version 17.7.6
VisualStudio.17.Release/17.7.6+34221.43
Microsoft .NET Framework
Version 4.8.09032
Now I get the error message at the start:
PS D:> root
Assertion failed: !(isOverridden && isOutOfDate) && “an overridden cannot be out-of-date”, file C:\ROOT-CI\src\interpreter\llvm-project\clang\include\clang/Serialization/ModuleFile.h, line 78
This is strange, because it used to work. Anyway, problems. Pls, tell me which version to install how, etc. I want:
a) Win 11 64 bit
b) VC17
c) powershell integration
d) no pyton, cmake, etc.
I just downloaded root_v6.32.08.win64.vc17.zip, on my Windows 11 desktop, unzipped it in C:\root, then started a Developer PowerShell for VS 2022, and then, from there:

1.) Could you, please, run the example below with “.x test.cpp” twice. The second time it fails.
2.) Could you compile it with “.x test.cpp++”. It returns an error.
My experience is with older versions of root. Never had the above problems.
I am used to running heavy scripts, which have to be compiled, otherwise they take long. The interpreter is not an option for those.
Here is my example “test.cpp”
#include "iostream"
using namespace std;
void test()
{ cout<<"blabla"<<endl;}
As the error message it telling, you build fox x86 architecture while ROOT has been built for x64. Please start a x64 PowerShell (make sure the DevCmdArguments are -arch=x64 -host_arch=x64)
It seems the only PS installed by visual studio is not 64bit.
1.) Can you, please, give me the exact syntaxis to set the DevCmdArguments?
2.) Or, would you recommend I download the 32bit binaries of root?
Do you really need PowerShell? Can you try first with a x64 Native Tools Command Prompt for VS 2022? I personally use a Windows Terminal (Version: 1.21.3231.0) from where you can invoke several command prompts and PowerShell
I am not IT, so my knowledge is basic. Yes, I prefer powershell, but cmd might be ok.
1.) Can’t setup the environment variables in cmd, which in powershell is done with: “C:\root\bin\thisroot.ps1”. Should I use the installation package instead?
2.) In the past I had a PS profile which setup VS for use in the powershell, and I used the installation package to set the variables for root. Can you provide a powershell profile that does both? Here is roughly (some folder names are guessed) what I had in the past, but I did not write it myself, so I hardly understand it.
