Hello,
I am trying to use shared_ptr for the Packet class. I changed "typedef Packet *PacketPtr" to "typedef std::shared_ptr<Packet> PacketPtr" and made all the needed associated changes. My code compiled fine, but I now have this linker error:
build/ARM/python/m5/param_Cache_Controller.cc:77: undefined reference to gem5::Cache_ControllerParams::create() const' build/ARM/python/_m5/param_Memory_Controller.do: In function
gem5::module_init(pybind11::module&)'
There are also similar errors for Memory_Controller, MiscNode_Controller, and TrafficGenerator_Controller.
Does anybody know how to fix this issue? Per a comment in build_tools/sim_object_param_struct_cc.py, "gem5::Cache_ControllerParams::create() const" is auto generated via some magic template trick that I don't understand.
Also, has anybody done something similar to this before and has pointers to share?
Thank you

Hello,
Is this on develop? I made some recent Ruby changes. If you create a github issue I can track this better
