I’m trying to build the newest installation of root (6.18.04) with a specific gcc version which is not the default on my system.
I have some other software that requires root to work that is having problems with ABI (something like the default C++ compiler and libraries being used have different ABI versions) and I’m seeing if I can fix the problem by using a newer C++ compiler. In this instance I’m using gcc 9.2.
Root has to be built with pythia 6 and I’ve tried to specify the c++ compiler by using the following cmake command;
/home/lar/cthorpe/cmake-3.15.2/bin/cmake -DPYTHIA6_LIBRARY=/home/lar/cthorpe/install2/root/lib/libPythia6.so -Dpyhia6=ON -DCMAKE_CXX_COMPILER=/home/lar/cthorpe/gcc_9_2/bin/g++-9.2 -DCMAKE_C_COMPILER=/home/lar/cthorpe/gcc_9_2/bin/gcc-9.2 ~/install2/root-6.18.04 > cmakeout.txt
The output from cmake is attached in case there is anything abnormal in there.
However make fails partway through. Running make with VERBOSE=1, make fails at the line:

On this system there is no
/lib64 however there is one in
~/gcc_9_2/lib64/ so I wonder if something I have done is causing it to look in the wrong place? (If that is the actual problem).
