Analyze and copy library dependencies of ELF binaries

copydeps's Issues

Error handling

It should be great to take care of potential exeptions (--destdir not writable or not exist for exemple) and output nice cli error (instead of crash with full stacktrace) with cli error code.

You can event use a lib to help you handle that.

Local shared objects do not work

Apparently whenever copydeps deals with a local .so it chokes and doesn't finish.

Example:
ldd some_elf
linux-vdso.so.1 => (0x00007ffeccfe7000)
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f92d170c000)
libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f92d14ef000)
./libSDL-1.2.so.0 (0x00007f92d1265000) <--------- THIS ONE
libstdc++.so.5 => /usr/lib/x86_64-linux-gnu/libstdc++.so.5 (0x00007f92d0f89000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f92d0c80000)

copydeps -d /home/nk/bin/some_elf_libs/ some_elf
Traceback (most recent call last):
File "/usr/local/bin/copydeps", line 9, in
load_entry_point('copydeps==1.0.0', 'console_scripts', 'copydeps')()

KeyError: './libSDL-1.2.so.0'

It's obvious that this particular lib is already inside the elf folder but specifying a destination directory should copy every .so that is needed by the loader no matter the .so location. Further, at least working other libs till the end would be ideal behavior with a simple error summary at the end if something went wrong (i.e. this and that libs could not be copied, etc).

Thanks!

[Blocking] Documentation improvements

After a quick look at the script, I have seen that it calls ldd and readelf which are not guaranteed to be installed (not on http://refspecs.linuxfoundation.org/LSB_5.0.0/LSB-Common/LSB-Common/rcommands.html ), and I'm not sure they are on the base install of most linux distributions.
It will be good to specify in the README that they are needed.

Also, it may seems obvious but as it is a python script it can run on Windows. We should specify that it's not supposed to be run on Windows.

Suggestion : replace Linux binaries by ELF binaries

[Blocking] Packaging

Hey, nice script 👍

It sould be great to organize the code to be distributed 'the python way'
https://docs.python.org/3.5/distutils/setupscript.html#installing-scripts
https://gehrcke.de/2014/02/distributing-a-python-command-line-application/

At least to put the script in a source folder and give him back his .py file extention :)
