Hi, Gabe,
Just to add some info (I forgot to try v21 last time):
To set USE_SYSTEMC=0 can make it through for version v20.1.0.5, but not
for latest v21.1.0.0. As u may already know, for v21.1.0.0 the following
errors appeared during building process:
build/ARM/python/_m5/param_A9SCU.cc:7:10: fatal error:
pybind11/pybind11.h: No such file or directory
7 | #include "pybind11/pybind11.h"

I guess I'd better use v20 until you get everything solved in later
release.
Thanks & BR
Shawn

Subject: Re: [gem5-users] util/tlm issue, need help
Hi, sorry for taking a while to get back to you. The cxx-config code is not
quite correct, although it basically works in most cases. It fails to build
with the systemc integration, but you don't want to use gem5's built in systemc
kernel anyway, if you're going to run it inside another external systemc
simulation. The util/systemc/gem5_within_systemc/README was updated to tell you
to set USE_SYSTEMC=0 on the command line, but it looks like we forgot to update
the tlm one. Ideally we'll fix the underlying issue one of these days, but
there are a lot of things to fix and only so much time. So, to get the build to
work, add USE_SYSTEMC=0 to the scons command line.

Dear Gem5 Users,
I‘ve got stucked when try to follow the tlm tutorial in
gem5/util/tlm/README.
(similar issues for versioin of GEM5 21.1.0.0<https://21.1.0.0/> &
21.0.1.0<https://21.0.1.0/>)
Following the section III of the README file, there is no issue on the
first two line and end with normal gem5.opt output:
> cd ../..
> scons build/ARM/gem5.opt
While the problem comes during the next command
> scons --with-cxx-config --without-python --without-tcmalloc

There comes several error report as below, the log file is also available as
attachment.
build/ARM/cxx_config/Gem5ToTlmBridge256.cc:144<https://gem5totlmbridge256.cc:144/>:24:
error: cannot convert 'sc_gem5::Gem5ToTlmBridge<256>*' to 'gem5::SimObject*'

I tried hard walking arround and have no ideal on how to get throught. I guess
it may be a common issue for those who’s trying to get through this tutorial.
Any advise on using the tlm utility of Gem5 will be great helpful.
By the way, it will make my life better if anyone could offer me any idea on
getting rid of the huge amount of namespace warning in building the new version
21.1.0.0<https://21.1.0.0/>.
Thank in advance
