Installation error about binwalk HOT 9 CLOSED

You shouldn't have gotten this error with file-5.14; make sure that you also installed the file-5.14 python wrapper, and that all other python magic wrappers are removed from your system.

With that said, you should never get this error with the binwalk code from the master branch. It has had its own libmagic python wrapper for some time to address these types of issues: https://github.com/devttys0/binwalk/blob/master/src/binwalk/core/magic.py

from binwalk.

Hi,

On CentOS with the file-5.14 intalled still doesn't work. With the PyQt or PySide installed, at runtime the error "PyQt needs the Qt 4.7 or above to work". The PyQt and PySide are installed by yum and your dependents packages are Qt 4.6 (fail on repository). Ok, i'm back to FreeBSD and installation work like a charm. But...

[fronald@sagan] ~/Labs/D-Link 2500-E% binwalk dlink2500e_retail.img
Segmentation fault

This error can appear because the master version is unstable? I'm running Python 2.7.6 on FreeBSD 10.

from binwalk.

Hmmm, possibly related to issue #30? Try running it in python with the -O switch and see if you get any debug output before the crash:

 $ python -O $(which binwalk) dlink2500e_retail.img

from binwalk.

Do it. And the error is:

DEBUG: libmagic.magic_open(0x328000)
DEBUG: libmagic.magic_load(0x1C19480, /tmp/tmpZGMiiX)
Segmentation fault

Curiously on the my Mac machine, the very similar error appear too. Segmentation fault at libmagic. This information help anything?

from binwalk.

The library integrity apparently is ok...

What the Linux distribution you use to develop binwalk? I can download and install that version in a virtual machine to test. If all ok, i'm back to FreeBSD to help you with the deploy. I can create a package for binwalk to FreeBSD and contribute with the project.

from binwalk.

From the debug output, it looks like it is crashing in libmagic's magic_load. This could be due to a bug in the new libmagic wrapper, or libmagic version incompatibilities.

I'm currently running on Ubuntu 12.04 with no problems; IIRC, I'm just using the libmagic that came with the distro - I'll try upgrading to 5.14 and see if I can replicate the issue.

from binwalk.

I've just tested binwalk on Ubuntu with both libmagic v5.09 and v5.14 without any issues. However, I may know what was causing your original problem..

When I installed the newer file v5.14, the supporting libraries (e.g., libmagic) were installed to /usr/local/lib; so even though the file utility reported that it was v5.14, the old libraries were still in the /usr/lib directory, so binwalk was still loading the older library (/usr/lib was first in my system's search path). Is this the case on your CentOS system as well?

from binwalk.

Binwalk now includes all core dependencies; if you grab the latest code from master, you shouldn't have these install problems anymore. The segfault (issue #30) has also been fixed.
