[Gate-users] error in CLHEP installation

Fri Mar 11 22:41:57 CET 2016

"C++11 extension not available" probably means the compiler at /usr/bin/c++ is too old. With the Gnu compiler I think you need at least 4.7 to support C++11. (That's off the top of my head. That may not be the exact version.)

Objet : [Gate-users] error in CLHEP installation

I'm trying to install Gate7.2, but in CLHEP installation after typing "cmake -DCMAKE_INSTALL_PREFIX=/PATH_TO/ /PATH_TO/" with appropriate path, this error occurs:
