Build fails due to some issue in unicorn_afl

[nishant412]

I am trying to build AFLplusplus from source following the instructions on here - https://github.com/AFLplusplus/AFLplusplus/blob/stable/docs/INSTALL.md

When I run make distrib it seems to error out during unicorn_mode build stage. Here is what I observed:

[ 94%] Built target sample_x86
make[3]: Leaving directory '/home/nb-ap@THP.LOCAL/Tools/AFLplusplus/unicorn_mode/unicornafl/unicorn/build'
make[2]: *** [Makefile:146: all] Error 2
make[2]: Leaving directory '/home/nb-ap@THP.LOCAL/Tools/AFLplusplus/unicorn_mode/unicornafl/unicorn/build'
make[1]: *** [Makefile:11: unicorn/build/libunicorn-common.a] Error 2
make[1]: Leaving directory '/home/nb-ap@THP.LOCAL/Tools/AFLplusplus/unicorn_mode/unicornafl'
make: [GNUmakefile:651: distrib] Error 1 (ignored)

Any suggestions on how to resolve this? I am running Ubuntu 22.04.1 LTS on a x86_64 machine

Edit : Looking at the output logs better, I realize this is where the errors start

[ 93%] Building C object CMakeFiles/sample_x86.dir/samples/sample_x86.c.o

@make[4]: *** [CMakeFiles/bundling_target.dir/build.make:73: libunicorn.a] Error 9

I am guessing the arguments to the call to ar don't have quotes correctly, coz it seems to ignore my home directory name after the @ . Where should I edit to fix this?

sorry I somehow never saw this issue.
easy fix: build under a different user, e.g. root, and do sudo make install.

also the repo that would need the fix is this one: https://github.com/AFLplusplus/unicornafl
