In the past it happened several times that some changes in gem5 broke the SystemC coupling. Recently Accelera has changed the licence for SystemC from their own licence to Apache2.0, which is compatible with gem5. However, SystemC usually relies on the Boost library, but I was able to exchange the boost calls by c++11 alternatives. The recent SystemC version is placed into /ext and is integrated into gem5's build system. The goal is to integrate some SystemC tests for the CI in some following patches.
