Compilation error on Windows 10

ROOT Version:_ ROOT 6.26.04
Platform: Windows 10

Dear All,
I’ve followed the installation instructions reported in “build from source” but I obtain the following error

CustomBuild:
  "La compilazione di 'C:\Users\itk-dcs\ROOT\root_build\CMakeFiles\867b3fefe352907a48d075fa9152f040\hsimple.rule' dipende da 'C:\USERS\ITK-DCS\ROOT\ROOT_BUILD\TUTORIALS\HS

it says it’s impossible to compile the elements associated to hsimple* in parallel; have you never seen this error? How can I fix it?
Thanks,

Welcome to the ROOT Forum!
What is the exact version of Visual Studio you are using (e.g. v16.11.15)?
Why don’t you take a pre-compiled binary distribution?

Hi,
thanks a lot for the link. Sorry but I’ve looked for an older version, where there is no window version available, and I’ve thought it is not anymore supported. I’ll try it and, in case I will have problem with my code calling the root library, I’ll come back to you.
Just to let you know that the version of Visual Studio is v16.11.15.
Cheers,
Luigi
