Interesting.

It's not clear to me why this won't work. Could you please try to add

#include <string.h>

at the beginning of the file green_function.hpp in /home/t/alps_build/alps/applications/dmft/qmc/?

That may do the trick.

Dear developers,

is it possible to compile ALPS in Archlinux? I always obtain the errors like:

Is it compiler version issue or something else? Please, see also short discussion about that https://aur.archlinux.org/packages.php?ID=55549
