ImportError: ERROR: fail to load the dynamic library. about qiling

[chfl4gs]

Workaround until upstream fix.

cp /usr/local/lib/python3.6/dist-packages/usr/lib/python3/dist-packages/keystone/libkeystone.so /usr/local/lib/python3.6/dist-packages/keystone/

I guess running a ldconfig should fix the issue as mention in keystone installation guide.

i will add a note into qiling installation guide too.

ldconfig does not solve this. mainly since it's not a ld path issue, rather it's a keystone library placed into wrong location issue:

sudo ldconfig
[sudo] password for user:
(qiling) ✔ ~/work/opt/qiling [master|✔]
14:23 $ ./qltool
Traceback (most recent call last):

Please send a pull req to Keystone for this issue.

It appears the python library for keystone is over 3 years old. The source may be correct in the git tree, but it's never been pushed to pypi.

[xwings]

Ah, this is pypi issue. not the original install from source issue

[bannsec]

Right. When installing qiling it uses the pypi version of keystone. Many other libraries also rely on keystone library from pypi. Surprised this is still a bug.

if you are able to fix it, please sent in a pull request to keystone

[bannsec]

It appears to possibly already be fixed. Issue being that keystones last push to pypi was over 3 years ago. It needs to be pushed.

@chfl4gs can you please check ? or update the the documents

[phdphuc]

Having issue with Keystone installation (keystone-engine>=0.9.1.post3) on macOS Catalina, due to macOS won't support 32bit executable furthermore. Same issue has been reported here

Temporary workaround:

Remove keystone-engine>=0.9.1.post3 in requirements.txt and install keystone-engine python binding from source.

I have the same problem."cp /usr/local/lib/python3.6/dist-packages/usr/lib/python3/dist-packages/keystone/libkeystone.so /usr/lib/ " .I sovled the problem

[0xjacklove]

you just need to check kestone.py
