Compilation Errors (error: use of undeclared identifier 'KBUILD_MODNAME') #1

I'm getting an error when I tried to compile CXLMemSim. I'm using Ubuntu22.04 with kernel version 5.19.1-051901-generic. I simply used cmake . && make. Following is the error message I got:

Using the build commands provided in CXLMemSim/artifact/build_and_run_all.sh gives the same error, together with a missing jemalloc error.

Any hint would be very helpful. Thanks!

Just comment out the line with NL_SET_ERR_MSG_MOD.
