this is not a good issue.
what is your setup? linux distribution, did you set your compilation to e.g. mips, sparc, ... ? what compiler are you using etc.
I'm having the same problem.

hmm it builds for me, even with gcc-12.
you both report different make errors.
But I seed different stuff here:
[1/2112] Compiling C object libcapstone.a.p/capstone_cs.c.o
[2/2112] Compiling C object libcapstone.a.p/capstone_MCInstrDesc.c.o
and
[1/8504] Generating qemu-version.h with a meson_exe.py custom command
[2/8504] Compiling C object libqemu-cris-softmmu.fa.p/tcg_tcg-op.c.o
for me it is
[1/975] Generating trace/generated-helpers.c with a custom command
[2/975] Generating trace/generated-tcg-tracers.h with a custom command
so much less compilation steps.
I mentioned in #45 as noted by the autogenerated github "mention" comment above.
I will comment here for posterity and limited confusion.
The top level comment is probably compiling without CONFIG_USER_ONLY.
This will happen if they try to compile prior to reading the docs which explains that build_qemu_support.sh must be run. With no real information in the OP, I suspect that this was their intent. To be fair, this is easy-ish to miss if you are not familiar with the codebase.
ctrl+f in the README for AFLplusplus presents nothing.
The other comment explains that they built this in-tree with specific configuration options: ../configure --disable-werror --target-list=x86_64-softmmu. While not the intended usage, I believe that this is a legitimate usage
softmmu targets are not supported, stick to build_qemu_support.sh in AFL++
