Works fine here too. I also think it looks pretty good. Something I like is that it looks like I will be able to contribute myself to keeping the config files in good shape. I didn't really want to touch them before (because of their size and complexity). I guess we would also need to provide Makefiles instead of SConstruct for all the demos. We could have one demo demo/build/cpp which contained various ways to build against DOLFIN, including plain Makefiles, SConstruct and possibly other options. The next step will be to add support for generating the pkg-config file for DOLFIN. Btw, I set build directory = install directory = pwd/local. Is that good practice or is there a reason for separating build directory from installation directory? -- Anders
