Installing ROOT with CUDA

[Anantha_Padmanabhan]

Dear Experts, on the page building from source on the official ROOT’s installation page, the following steps are recommended.

rem The `latest-stable` branch gets updated automatically on each release.
rem You may update your local copy by issuing a `git pull` command from within `root_src`.
C:\Users\username>git clone --branch latest-stable --depth=1 https://github.com/root-project/root.git root_src
C:\Users\username>mkdir root_build root_install && cd root_build
C:\Users\username>cmake -G"Visual Studio 16 2019" -A Win32 -Thost=x64 -DCMAKE_VERBOSE_MAKEFILE=ON -DCMAKE_INSTALL_PREFIX=../root_install ../root_src
C:\Users\username>cmake --build . --config Release --target install
C:\Users\username>..\root_install\bin\thisroot.bat

How do I build it with CUDA support? Because in the Debug, it oututted that CUDA is not found, but nvcc and nvidia-smi works perfectly fine on my PC.

Is there any fix for this?

Thanks in advance

Hi,

The doc is here Building ROOT from source - ROOT . Adding @bellenot in the loop.

Note that ROOT with CUDA has vever been tested on Windows. It might not work…

I see, I guess i have to switch to WSL. Thanks Evenryone!

Well, if you want to give it a try, then we would know if it works or what fails…

Sure @bellenot , I have tried installing it in windows and i got the following error:

I’m no expert, anyway, i was able to install it in WSL

Thanks
