Hi there, Well that is something I have not seen before: it looks like it did not link correctly to your copy of libpthread.so. To confirm this, could you run
ldd build-directory/lib/libdeal_II.so (where build-directory is whereever you compiled the library) and see if it did not find a particular library. Since it looks like the library is in '/root/': did you compile this as root? If so weird things can happen; you should build it as an unprivileged user.
