Dear Buildroot list,

I'm trying to create a  Buildroot package for the Crossbar.io python
software. This package has a lot of dependencies, and I'm slowly working
through them.

I'm picking up a similar issue as

<https://her-webmail.sansa.org.za/owa/redir.aspx?C=ef424837439d4f8283da45e6a6a2085f&URL=http%3a%2f%2flists.busybox.net%2fpipermail%2fbuildroot%2f2015-March%2f121816.html>
 in compiling python-cryptography (development platform is 64bit Ubuntu,
cross compiling for 32-bit) - the wrong cffi backend is chosen: "wrong ELF
class: ELFCLASS32" (cffi compiled fine for the correct architecture,
cryptography is using the host info.)

Can anybody in assisting to get a python-cryptogarphy module to correctly
crosscompile?

Regards

Herman
