Newbie

ROOT Version: v6-36-00-rc1
Platform: Windows Server 2016 Version 1607
Compiler: Visual Studio 2022 v17.3.6

Hello,

I tried to build ROOT 6.36 on Windows Server 2016 for my clients. However I face a header copy issue.

RooCategory.h seems to be missing.

Do you know where the issue may come from on Windows Server 2016 & how to solve it?

Best Regards,

Hi, we (at CERN) always build from Windows 10 & 11. We have no experience with Windows Server. One thing I can think of is maybe the PATH being too long (i.e. the full PATH of D:/[...]/root/my_build/include/)…

Other trick could be to reduce the number of headers copied at once, from 1000 to 100 or something like that.

Hello,

I changed the build directory from:

-- Build files have been written to: D:/Users/[...]/prerequisites/root/my_build

to:

-- Build files have been written to: D:/uranie-ci/prerequisites/root/my_build

And ROOT 6.36 was successfully built on Windows Server 2016:

[...]
  -- Installing: D:/uranie-ci/builds/[...]/root/cmake/modules/FindVdt.cmake
  -- Installing: D:/uranie-ci/builds/[...]/root/etc/notebook/jupyter_notebook_config.py
  -- Installing: D:/uranie-ci/builds/[...]/root/etc/notebook/kernels/root/kernel.json

I feel a bit ashamed :sweat_smile:

Thank you very much!
