===== Compiling Abinit ===== Compiling abinit once you have configured is usually as simple as make and going to have a coffee. If abinit has to compile fallbacks for libxc and other libraries it can take 10-20 minutes on a slow machine. You can make with several threads (here 4) at the same time to go faster: make -j 4 The build system is clever and does things in the right order to not get ahead of itself (it has to build modules before it uses them). As a rule -j is a good idea. If things do stop and the compiler complains, run make again without threads to be sure it's not simply an issue of precedence.
