1 year ago 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.

1 year ago 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
