ROOT installation Windows problems

faca87 · March 31, 2021, 1:30pm

Unfortunately, if I write in that way, it say that cmake-gui isnt’ a known internal or exeternal command etc

Then open it from the Windows start menu, it should be part of CMake

faca87 · March 31, 2021, 1:35pm

It looks like that I don’t have Cmake in the start menù

and in the programs directory too

Maybe, do I have to install something more than Visual Studio?

Maybe this one https://github.com/Kitware/CMake/releases/download/v3.20.0/cmake-3.20.0-windows-x86_64.msi ?

So I don’t know where your CMake is coming from (maybe Visual Studio), but I would advise you to find a way to get CMake-Gui, it will be very useful.

I installed cmake

and i did cmake-gui .

this is the log

but Cmake can’t still find HepMC… I don’t know…

So you’re telling me that HepMC doesn’t find HepMC? What you show me if the screenshot for HepMC. You should specify that in Geant4 (or did I miss something?)

faca87 · March 31, 2021, 2:00pm

So…do I have to type cmake-gui . in the simulation directory?

bellenot · March 31, 2021, 2:02pm

You should know. You told me cmake doesn’t find HepMC, but when did cmake complain about that? When doing what?

faca87 · March 31, 2021, 2:11pm

Ok I explain better:

I’ve the directories

C:\Program Files\geant4_10_07_p01 : Geant4 sources downloaded from geant website
C:\Program Files\geant4_10_07_p01_build : Here I built Geant
C:\Program Files\geant4_10_07_p01_install : Here I installed Geant

C:\Program Files\HepMC3: HepMC sources downloaded from HepMC website
C:\Program Files\HepMC3-build : Here I built HepMC
C:\Program Files\HepMC3-install: Here I installed HepMC

C:\B1: Main directory of my simulation
C:\B1\B1-build: Here I must build my simulation

Then I lunch the commands

cd “C:/B1/B1-build”
cmake -DGeant4_DIR="C:\Program Files\geant4_10_07_p01_install\lib\Geant4-10.7.1" "C:\B1"

and I get the errore due to missing HepMC

so geant can’t build the simulation…

then in which directory should I cd and how should I sed the cmake-gui?

bellenot · March 31, 2021, 2:19pm

So you have two choices, in C:/B1/B1-build:

type:

cmake -DGeant4_DIR="C:\Program Files\geant4_10_07_p01_install\lib\Geant4-10.7.1" -DHEPMC_INCLUDE_DIR="C:\Program Files\HepMC3-install\include" -DHEPMC_LIBRARIES="HepMC libraries"

and obviously replace "HepMC libraries" by the required libraries and adjust the correct include directory.

open CMake-GUI in the directory and use the GUI to fill those variables.

As a more general comment I think you should try things out by yourself at some point, it’s a good way of learning…

Thank you…it looks like that this way works…or better…I have errors during the run but I think they are because of I don’t know which libraries I’ve to inlcude then I just wrote -DHEPMC_LIBRARIES="HepMC libraries" …so I’ve to try

Right, but it’s not my simulation…it’s the simulation of my supervisor’s collegue… My supervisor asked me to help his collegue making the simulations…but I never used HepMC in my Geant4 simulations, so I don’t know how to use it…and you know…supervisors always want works in few times…

faca87 · March 31, 2021, 5:46pm

I also tried the cmake-gui . method and now it looks like that it find hepmc, but later I get the same error that I got using the first method…then maybe it’s a problem related to Geant…so, thank you @bellenot…now I’ve to solve the Geant problem!

bellenot · March 31, 2021, 6:15pm

Yes, I know, don’t worry

You’re welcome! And good luck with it, I’m sure you will find the solution
