Root with 64 bit compiler

Just a simple question:
I am compiling root for windows 11 64 bits with visual studio 2019.
I do the following (root6.27.01):

git clone --branch latest-stable --depth=1 GitHub - root-project/root: The official repository for ROOT: analyzing, storing and visualizing big data, scientifically root_src
cmake -G"Visual Studio 16 2019" -A x64 -Thost=x64 -DCMAKE_VERBOSE_MAKEFILE=ON -DCMAKE_INSTALL_PREFIX=D:\Libraries\ROOT\root_install_windows -DCMAKE_CXX_STANDARD=17 -Dqt5web=ON -Dwebgui=ON -Droot7=ON -DQt5_DIR=D:\Qt\5.15.2\msvc2019_64\lib\cmake\Qt5 D:\Libraries\ROOT\root_src
cmake --build . --config Release --target install – /maxcpucount

But I get an error:

Microsoft (R) Build Engine version 16.11.2+f32259642 for .NET Framework
Copyright (C) Microsoft Corporation. All rights reserved.

MSBUILD : error MSB1009: Project file does not exist.
Switch: install.vcxproj

I have read in another thread of this forum that we can compile root with x64. What do I miss?

Yes, ROOT compiles fine on Windows x64. Can you try without --target install first?

Hi,

If you want to compile Qt5 plugin on Windows, I recommend to set PATH variable like:

set PATH=%PATH%;D:\Qt5\5.15.2\msvc2019_64\bin

In such case one could skip: -DQt5_DIR=D:\Qt\5.15.2\msvc2019_64\lib\cmake\Qt5

Thank you for your response. Unfortunately I have the same error when trying with
cmake --build . --config Release

The result of cmake writes the following. It might contain indications for the issue? It does not find python but I do not need root-python.

Compiling with -A Win 32 works but not -A x64

Python is needed, even if you don’t want PyROOT. And obviously, if you build in 64 bit, it should also be in 64 bit. Note that if 32 bit works for you, then just use it in 32 bit.

I get very similar cmake result in 32 bit except for the “configuring incomplete” at the end:

Unfortunately I need ROOT to be built in 64 bit because I want to integrate it in a project that is 64 bits

can you try to install numpy? (pip install numpy) and try again (in 64 bit mode)

Ok, I will have to review my python setup because I cannot execute pip in the prompts. It seems there are versions in the microsoft store and as executable. I will make different tests and post the results here

Indeed it was my python-numpy setup that was not correct… Thanks.
I also have one last question. I use root inside a QT application built with QtCreator (qmake from a .pro file).
I do the correct linking in the pro file and the compilation works perfectly.

  1. When I start the application inside QTcreator, it asks me for the ROOT dll. I read on another thread that we should not put the dll next to the .exe. How can I execute my application inside QTcreator?
  2. In the same way if I execute the .exe outside QTcreator, it asks for the ROOT dll. Adding the path in my environment variables should fix this but if I want to install my application on another computer, is there another way than installing the full ROOT application?

PS: executing my application from a shell after sourcing thisroot.bat works perfectly.

Thanks a lot

You’re welcome!

And in short: you need the full ROOT installation. It’s not just the dlls that are needed. ROOTSYS must be set and ROOTSYS\bin in the PATH (it’s what thisroot.bat does). ROOT needs several things (like the plugins, options, … ) in the PATH relative to ROOTSYS
