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.

Overview
This repository is a redistribution of the Accellera SystemC 2.3.1 library [1]. This distribution replaces Accellera's Autoconf build system with a SCons build system, which is very useful for integration of SystemC in other SCons based projects, e.g., gem5 [2].
The repository contains all the source files from the Accellera distribution, but strips down the boost dependencies. All references to the boost library are replaced by calls to the C++11 STL. This repository also contains the TLM 2.0 protocl checker from Doulos [3].
Build
To build libsystemc-2.3.1.so, simply type scons. Optionally you can specify the number of jobs.
scons -j N
To build and link to SystemC from another SCons project, simply call the
SConscript located in src/. Be sure to add -std=c++11 to the CXXFLAGS of
your environment and to export the environment as 'env'. In case you build on
OS X, you will need to add -undefined dynamic lookup to your LINKFLAGS.
This is how a minimal SConstruct for your SystemC project could look:
env = Environment()
env.Append(CXXFLAGS=['-std=c++11'])
if env['PLATFORM'] == 'darwin':
env.Append(LINKFLAGS=['-undefined', 'dynamic_lookup'])
systemc = env.SConscript('<path_to_systemc>/src/SConscript', exports=['env'])
env.Program('example', ['example.cc', systemc])
