Looks like this JIRA is low priority and has no progress since 2021.
Thanks a lot!

Hi Ginger,
We didn't try to run gem5 as dynamic lib inside SystemC. 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

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.

Hello Yu-hsin,
Just saw you are the main edtor of tlm bridge to sysc, maybe you are the right
person? :)
In the bridge, this->create() will return a Gem5ToTlmBridge type which is
incompatible with SimObject as below declared, any comments? Thanks a lot!
SimObject *
Gem5ToTlmBridge32CxxConfigParams::simObjectCreate()
{
return this->create();
}

| Subject | [gem5-users] GEM5 within SystemC build issue |
Hello,
Anyone went well with GEM5 and SystemC integration?
I triied to build libgem5_debug.so so I can integrate GEM5 in a standalone
systemc environment with below commandline:
python3 `which scons` --with-cxx-config --without-python --without-tcmalloc
USE_SYSTEMC=1 build/RISCV/libgem5_$(BUILD_TYPE).so -j 32
But I got below issue with "--with-cxx-config" option.
build/RISCV/cxx_config/Gem5ToTlmBridge32.cc: In member function ‘virtual
gem5::SimObject* gem5::Gem5ToTlmBridge32CxxConfigParams::simObjectCreate()’:
build/RISCV/cxx_config/Gem5ToTlmBridge32.cc:149:24: error: cannot convert
‘sc_gem5::Gem5ToTlmBridge<32>*’ to ‘gem5::SimObject*’ in return
149 | return this->create();
| ~~~~~~~~~~~~^~
| |
| sc_gem5::Gem5ToTlmBridge<32>*
if I do without this option, assertion fired in below, complaining:
main.cc:280: fatal: Config problem in sim object root: No sim object type Root
is available
