Hello，When I try to compile afl in V-Shuttle-S/afl-seedpool, I get the following error：

Oops, the instrumentation does not seem to be behaving correctly!

Please ping <lcamtuf@google.com> to troubleshoot the issue.

make: *** [Makefile:95: test_build] Error 1

My virtual machine operating system is ubuntu 20.04，gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0

[cyruscyliu]

It's because of this early return in afl-gcc.c.

  #define DEVICE_DIR "hw/"
  if(!strstr(cc_params[cc_par_cnt - 1], DEVICE_DIR))
    return;

As said by the author in README.md "Ignore the errors reported in AFL compilation ("Oops the instrumentation dose not seem to be behaving correctly").", I think we can ignore this.

At the same time, update install: all in Makefile to install:, which would remove the error when executing make install.

Hacky. Anyway.

Hello,when I try to make the QEMU(version 6.2.0) as the README said, I met the following questions:

It seems that something wrong with the memory.c, but I think it is a source code from QEMU?
Is there anyone met the same qeuestions?

[cyruscyliu]

I guess you replace memory.c? You can just simply apply this patch as memory.c changes.

ok ok thanks!

[Chan9Yan9]

I found that QEMU 6.2.0 uses ninja to make, this lead to the errors I met
