Geant4 with Qt6 on MacOS Sonoma 14.5: Symbol not found: _FT_Get_Color_Glyph_ClipBox

asantra · May 24, 2024, 6:06pm

Dear experts,
I am trying to install Geant4 on my Mac with Qt6. I am building from the source using cmake.
The cmake flags are the following:

cmake -DCMAKE_INSTALL_PREFIX=/Users/arkasantra/Geant4_Install_Qt6 -DGEANT4_INSTALL_DATA=ON -DGEANT4_BUILD_MULTITHREADED=ON -DGEANT4_USE_OPENGL_X11=ON -DGEANT4_USE_PYTHON=ON -DGEANT4_USE_QT=ON -DGEANT4_USE_QT_QT6=ON -DGEANT4_INSTALL_EXAMPLES=ON  -DGEANT4_USE_SYSTEM_ZLIB=ON -DGEANT4_BUILD_TLS_MODEL=global-dynamic -DGEANT4_USE_GDML=ON -DCMAKE_PREFIX_PATH=$(brew --prefix qt) -DCMAKE_CXX_STANDARD=20 -DGEANT4_USE_FREETYPE=ON -DGEANT4_USE_RAYTRACER_X11=ON /Users/arkasantra/geant4-v11.2.1

The configuration message from the system is the following:

The compilation using cmake --build . -j8 is successful.
Subsequently, I built the geant4-v11.2.1/examples/basic/B1 using:

cmake -DGeant4_DIR=$HOME/Geant4_Install_Qt6/lib/Geant4-11.2.1 ../B1
make -j8
make install

Again there is no issue during the compilation.

However when I am running ./exampleB1, I am getting:

dyld[42928]: Symbol not found: _FT_Get_Color_Glyph_ClipBox
  Referenced from: <CD3FC454-4C6D-38DE-904E-B105A6499B06> /usr/local/Cellar/harfbuzz/8.4.0/lib/libharfbuzz.0.dylib

zsh: abort      ./exampleB1

May I know what is going wrong here? Any suggestion/comment to solve this issue will be greatly appreciated.

Thank you very much,
Arka

As you’ve configured with a mix of Qt and X11, it looks like which Freetype library to use is getting mixed up, likely due to rpath/etc ordering. As X11 on macOS via XQuartz is using its own Freetype library, whilst Qt6 is using one from Homebrew, I think the only solution is to pick either X11 or Qt5/6 to avoid such couplings - but which is entirely up to you.

Qt is the more fully featured system, but note that issues on the Qt6 support are still being ironed out.

Dear @bmorgan ,
Thank you for the heads up.
I reinstalled Geant4 with X11 turned off and based only on Qt5.
This is the cmake command:

cmake -DCMAKE_INSTALL_PREFIX=/Users/arkasantra/Geant4_Install -DGEANT4_INSTALL_DATA=ON -DGEANT4_BUILD_MULTITHREADED=ON -DGEANT4_USE_OPENGL_X11=OFF -DGEANT4_USE_PYTHON=ON -DGEANT4_USE_QT=ON -DGEANT4_INSTALL_EXAMPLES=ON  -DGEANT4_USE_SYSTEM_ZLIB=ON -DGEANT4_BUILD_TLS_MODEL=global-dynamic -DGEANT4_USE_GDML=ON -DCMAKE_PREFIX_PATH=$(brew --prefix qt@5) -DCMAKE_CXX_STANDARD=20 /Users/arkasantra/geant4-v11.2.1

The subsequent compilation and installation went fine.

I wanted to check the examples/basic/B1, so I followed this:

cd $Geant4_Installation/examples/basic/B1
mkdir build && cd build
cmake -DCMAKE_CXX_STANDARD=20 ../
make -j8

But this time I see the compilation is NOT successful:

Seems again the Qt5 is the problem.
I installed Qt5 using brew.
My system has Qt6 installed as well, but I made sure that in the PATH variable, Qt5 comes before the Qt6:

PATH=/usr/local/opt/openjdk/bin:/usr/local/opt/jpeg/bin:/usr/local/opt/krb5/sbin:/usr/local/opt/krb5/bin:/usr/local/opt/qt@5/bin:/usr/local/opt/qt/bin:/opt/anaconda3/bin:/opt/anaconda3/condabin:/usr/local/opt/gnu-getopt/bin

May I know how I should solve this problem?
I am using CMAKE_CXX_STANDARD=20 , will this be a problem?

Thank you once again,
Arka

Unfortunately, the only way to build with Homebrew qt@5 if you have qt (i.e., Qt6) installed is to unlink the qt Formula. Its headers will otherwise be picked up before those of the qt@5 formula, leading to the above error. The PATH and C++ standard have no impact on this behaviour as it’s related to compiler header search paths.

Unlinking qt is usually safe unless you’re actively relying on it for other projects.
