1This directory contains a demo of C++ configuration of gem5. The intention
2is to provide a mechanism to allow pre-generated config.ini files generated
3by Python-based gem5 to be reloaded in library-base versions of gem5
4embedded in other systems using C++ calls for simulation control.

7onto SystemC's event loop. The hosting is achieved by replacing 'simulate'
8with a SystemC object which implements an event loop using SystemC scheduler

28First build gem5 as a library with cxx-config support and (optionally)
29without python. When building the library, disable gem5's native SystemC
30API support, as that will conflict with the external version. Also build a
31normal gem5 (cxx-config not needed, Python needed):

33> cd ../../..
34> scons build/ARM/gem5.opt
35> scons --with-cxx-config --without-python USE_SYSTEMC=0 \
36> build/ARM/libgem5_opt.so
37> cd util/systemc
38
39Note: For MAC / OSX this command should be used:
40> scons --with-cxx-config --without-python USE_SYSTEMC=0 \
41> build/ARM/libgem5_opt.dylib
42
43Set a proper LD_LIBRARY_PATH e.g. for bash:
44> export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/path/to/gem5/build/ARM/"
45
46or for MAC / OSX:
47> export DYLD_LIBRARY_PATH="$DYLD_LIBRARY_PATH:/path/to/gem5/build/ARM/"
