I am trying to compile it from conda environment(for Qt5) but it throws several warning, e.g

runtime library [libexpat.so.1] in /usr/lib/x86_64-linux-gnu may be hidden by files in:
      /home/pranto/miniconda3/envs/geant4/lib
    runtime library [libfreetype.so.6] in /usr/lib/x86_64-linux-gnu may be hidden by files in:
      /home/pranto/miniconda3/envs/geant4/lib
    runtime library [libz.so.1] in /usr/lib/x86_64-linux-gnu may be hidden by files in:
      /home/pranto/miniconda3/envs/geant4/lib

although those libraries are found on root file which actually I want

-- Found EXPAT: /usr/lib/x86_64-linux-gnu/libexpat.so (found version "2.2.9") 
-- Found ZLIB: /usr/lib/x86_64-linux-gnu/libz.so (found version "1.2.11")

-- Found X11: /usr/include   
-- Looking for XOpenDisplay in /usr/lib/x86_64-linux-gnu/libX11.so;/usr/lib/x86_64-linux-gnu/libXext.so
-- Looking for XOpenDisplay in /usr/lib/x86_64-linux-gnu/libX11.so;/usr/lib/x86_64-linux-gnu/libXext.so - found

I have also tried to install run time library into my conda environment

conda install -c conda-forge expat freetype xerces-c xorg-libx11 xorg-libxfixes xorg-libxmu

But still same error.
Is it possible to pass additional cmake arguments to take run time library from root file rather than conda lib?

Hi all,

I have solved this problem.

Could you add some details on how you solved it?

Future readers with a similar issue who find this post will thank you :wink:

@php1ic Sorry for the late reply.

In .zshrc/.bashrc/

export GEANT4_INSTALL=<Geant4 install path>
# Geant4 install path is the path specified by "CMAKE_INSTALL_PREFIX" when building Geant4

@php1ic @bmorgan I want to install geant4-v_10.7.0 from conda-forge. Is it available now?

OK, currently it’s not available from conda-forge channel but a PR geant4 v10.7.0 is on the way.

Thanks for the cmake options and the conda install EVERYTHING_needed. It helps me a lot. Then a remark to say that I had an old conda installation. It was not possible to install this even after creating the “geant4” environment with python3.9. I had to re-install a fresh anaconda to be able to compile Geant4 10.7.p01. Apart from these everything went fine. It could help others. On more recent machine a conda update was sufficient before creating the geant4 environment, but not for “too old” anaconda installation (like started at python3.7 and updated not regularly).
