Problem Installing Garfield

[Johann_Mazzacaro]

Im getting the following error when installing Garfield, im kind of a newbie when using Linux and I have tryed fixing this many times. Im trying to install Garfield on my Ubuntu22.04 LTS. I have installed the precompiled version of ROOT6.26/02 and Geant4 10.7.3, which I compiled myself. Both are working fine, but when I try to Make garfield, the following errors happen: Can someone maybe help me?

Hi,
you need to make sure that ROOT, Geant4 and Garfield++ are compiled using the same C++ standard:

Problem in installation

You can build a c++14 aware Geant4 using: cmake -DGEANT4_BUILD_CXXSTD=14 ... If you want to have everything using c++17, you need to build ROOT using “cmake -DCMAKE_CXX_STANDARD=17” and Geant4 using “cmake -DGEANT4_BUILD_CXXSTD=17” Note that, afterward, in any case, you also need to build Garfield++ with the same C++ standard (I guess @hschindl can tell you how).

Installation was fixed, thank you very much for your reply!
