Aircrack-ng fails to open crypto lib (missing) on AVX512 CPU

[george369]

Getting this error when trying to run aircrack-ng:

Could not open '/usr/lib/x86_64-linux-gnu/libaircrack-crypto-x86-avx512.so': /usr/lib/x86_64-linux-gnu/libaircrack-crypto-x86-avx512.so: cannot open shared object file: No such file or directory

What version of aircrack-ng are you running?
Version 1.4

And what is the output of lscpu?

Is it coming from a package or compiled from source?
Same error occurs either or.

If package, what OS?

DISTRIB_ID=Kali

Running with VMWare on a Win10 machine.

If from source, what was the ./configure command?
./configure

Tried a fresh install of Kali but no luck. Also tried fresh installs of aircrack with and without avx512 (specified in ./configure command).

Thank you!

Hello,

I think it's detected that AVX512F is available, and looking for the shared libraries.

If you do NOT want AVX512F, then there is a bug - it shouldn't have crashed without it present.

If you DO want AVX512F, then an additional ./configure parameter is needed.

Best regards,

Hi Joe thank you for your reply.
The error is persistent even if AVX512 is specified in the ./configure parameter.
Either, or, the libraries cannot be detected.
Have tried both cases WITH and WITHOUT AVX512 enabled and the outcome is the same.
Thanks.

Would you mind posting the config.log and all output of ./configure --with-avx512=yes && make V=1 && make check V=1.

Thanks in advance!

A. Performed a clean installation of Kali.

B. Manually performed/installed the following:

1. apt-get install pkg-config
2. apt-get install libssl-dev
3. apt-get install libnl-3-dev linbl-genl3-dev
4. apt-get install libtool
5. apt-get install autotools-dev
6. apt-get install autoconf

C. Install aircrack 1.4 and use ./configure --with-experimental --with-avx512

Program works. It is still puzzling to me why this error showed up but in any case now program works fine. The program does not work if avx-512 is not specified in the ./configure command.

Hi there, I unfortunately have been having this exact same problem, first it was apparent to be on my Parrot install, tried reinstalling v1.4 manually with no avail, so thinking this might be a distro problem I tried it two times with a fresh install of Kali Linux, same problem coming straight from the pre installed package:

Could not open '/usr/lib/x86_64-linux-gnu/libaircrack-crypto-x86-avx512.so': /usr/lib/x86_64-linux-gnu/libaircrack-crypto-x86-avx512.so: cannot open shared object file: No such file or directory

Trying again on Kali performing an install of v1.4 manually, it had seemed to work fine with the /configure --with-avx512=yes && make V=1 && make check V=1 until I ran it with a test cap file, as it was trying to crack it the "Current passphrase:" part would show unknown characters, then crash with a Seg fault mid way through.

Finally the way I had fixed it at last by again installing manually and searching for the avx-512.so file, and doing the following cp command:

cp aircrack-ng/src/aircrack-crypto/.libs/libaircrack-crypto-x86-avx.so /usr/lib/x86_64-linux-gnu/libaircrack-crypto-x86-avx512.so

This seemed to fix it so far, nothing unusual happening.

Thanks for the detailed report.

I've made a change to load the maximum possible engine, based on what's on disk vs. what the CPU supports. Local testing on an AVX2 machine, with AVX512F compiled, does correctly load the AVX2 engine, now.

Thanks!

When i type aircrack-ng
It shows
