keystone-engine
[python] library is installed in a wrong directory with --user flag
version: 0.9.1
If I install keystone-engine with --user flag without virtualenv,
$ pip install --user keystone-engine
libkeystone.so is installed in a wrong directory, thus loading the keystone-engine throws an exception:
ImportError: ERROR: fail to load the dynamic library.
the libkeystone.so is installed in /home/username/.local/lib/python2.7/site-packages/usr/lib/python2.7/dist-packages/keystone/libkeystone.so, but it should be located in /home/username/.local/lib/python2.7/site-packages/keystone/libkeystone.so
it seems that capstone has the same issue.
Did you try this on latest Capstone code? If you did, can you open a new issue on Capstone repo?
it's broken in pip-installed version (3.0.4) of capstone, but seems it's fixed in the master branch of capstone.
we can fix this by porting the the Python binding of Unicorn to Keystone (as they are very similar). the only related Keystone file is https://github.com/keystone-engine/keystone/blob/master/bindings/python/setup.py, and the counterpart is https://github.com/unicorn-engine/unicorn/blob/master/bindings/python/setup.py
if you can fix this, please send pull req
with #301 merged, i think this issue is resolved. see the below terminal session building keystone on linux/python3:
before patch:
localhost:python (master*) $ git checkout d19579217c0ac71e2d63deb389f29fb23e5a9118
Note: checking out 'd19579217c0ac71e2d63deb389f29fb23e5a9118'.
You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:
git checkout -b <new-branch-name>
HEAD is now at d195792... clean travis and add linux (#315)
