Installing Geant4 10.06.p02

I was installing Geant4 10.06.p02 (I had previously version 10.04) and had an error during complication because the gcc version was an old version. The error was:

[ 10%] Building CXX object source/geometry/CMakeFiles/G4geometry.dir/magneticfield/src/G4VIntegrationDriver.cc.o /home/local/Geant4/geant4.10.06/source/geometry/magneticfield/src/G4FieldManagerStore.cc: In static member function ‘static void G4FieldManagerStore::DeRegister(G4FieldManager*)’: /home/local/Geant4/geant4.10.06/source/geometry/magneticfield/src/G4FieldManagerStore.cc:119:31: error: no matching function for call to ‘G4FieldManagerStore::erase(__gnu_cxx::__normal_iterator<G4FieldManager* const*, std::vector<G4FieldManager*> >&)’ GetInstance()->erase(i);

I had version gcc 9.2 but needed to change to 9.3 without root privileges. For that, you just need to install it in your account and change the library paths. Here is an example done at my /home/andreagutierre:

mkdir local

cd local

wget https://ftp.gnu.org/gnu/gcc/gcc-9.3.0/gcc-9.3.0.tar.gz

tar zxvf gcc-9.3.0.tar.gz

mkdir gcc-9.3.0-build

cd gcc-9.3.0-build/

./../gcc-9.3.0/configure --disable-multilib --prefix=/home/andreagutierre/local --enable-languages='c c++'

make

make install

Change your .profile or .bashrc and add (use your own path):

export PATH=/home/andreagutierre/local/bin:$PATH

export LD_LIBRARY_PATH=/home/andreagutierre/local/lib64

export LIBRARY_PATH=/home/andreagutierre/local/lib64

export CC=/home/andreagutierre/local/bin/gcc

export CXX=/home/andreagutierre/local/bin/g++

Then check: which gcc

~/local/bin/gcc

and: gcc --version

gcc (GCC) 9.3.0
