You may need to reach the maintainers. Here's a ticket you can refer. https://gem5.atlassian.net/browse/GEM5-874 Thanks.

Did tried and can pass build without this option, but hit below assertion so I suspect it has to go with cxx-config portion. main.cc:280: fatal: Config problem in sim object root: No sim object type Root is available | | G | | gingerluo@163.com | ---- Replied Message ---- | From | Yu-hsin Wang<yuhsingw@google.com> | | Date | 7/19/2023 15:32 | | To | G<gingerluo@163.com> | | Cc | gem5-users@gem5.org<gem5-users@gem5.org> | | Subject | Re: [gem5-users] Re: GEM5 within SystemC build issue | Hi Ginger, I think the issue is --with-cxx-config only works in SimObject case. However the Gem5-TLM bridges are all sc_modules instead of SimObject. I can get compile success without --with-cxx-config. Is that option required in your case? Thanks.
