Hey Gabe,
I (well, Hoa) was able to track this down a little bit. See the traceback
below. It looks like since Gem5ToTlmBridge is a SimObject, it's compiled in
by default pulling in the tlm header file.
In file included from build/X86/systemc/ext/tlm:24:0,
from build/X86/systemc/ext/tlm.h:22,
from build/X86/systemc/tlm_bridge/sc_peq.hh:41,
from build/X86/systemc/tlm_bridge/gem5_to_tlm.hh:75,
from build/X86/python/_m5/param_Gem5ToTlmBridge64.cc:9:
build/X86/systemc/ext/systemc:37:10: fatal error: boost/bind.hpp: No such
file or directory
#include <boost/bind.hpp>
^~~~~~~~~~~~~~~~
compilation terminated.
It would be great to fix this. It's been bugging me for a while that boost
has become a required dependency. I'm not sure what is needed and what
isn't. With some guidance we can take a stab at fixing this.
Thanks,
Jason
