I encountered the following error during the installation of the GEANT4 software after entering the command "make -j4":
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [BuildProducts/lib/libG4interfaces.dylib] Error 1
make[1]: *** [source/CMakeFiles/G4interfaces.dir/all] Error 2
make[1]: *** Waiting for unfinished jobs....
[ 15%] Built target G4particles
[ 23%] Built target G4geometry
make: *** [all] Error 2```
I tried "make -j4 -v" as it asks me to, which gave me the following output:
