Hi there, In OE rocko python cryptography will fail to load when built for cortexa15hf-neon-vfpv4. Plugin Extensions/OpenWebif failed to load: /usr/lib/python2.7/site-packages/cryptography/hazmat/bindings/_openssl.so: undefined symbol: pthread_atfork Traceback (most recent call last): File "/usr/lib/enigma2/python/Components/PluginComponent.py", line 52, in readPluginList File "/usr/lib/enigma2/python/Tools/Import.py", line 2, in my_import File "/usr/lib/enigma2/python/Plugins/Extensions/OpenWebif/plugin.py", line 29, in <module> from httpserver import HttpdStart, HttpdStop, HttpdRestart File "/usr/lib/enigma2/python/Plugins/Extensions/OpenWebif/httpserver.py", line 16, in <module> from twisted.internet import reactor, ssl File "/usr/lib/python2.7/site-packages/twisted/internet/ssl.py", line 59, in <module> File "/usr/lib/python2.7/site-packages/OpenSSL/__init__.py", line 8, in <module> from OpenSSL import crypto, SSL File "/usr/lib/python2.7/site-packages/OpenSSL/crypto.py", line 16, in <module> from OpenSSL._util import ( File "/usr/lib/python2.7/site-packages/OpenSSL/_util.py", line 6, in <module> from cryptography.hazmat.bindings.openssl.binding import Binding File "/usr/lib/python2.7/site-packages/cryptography/hazmat/bindings/openssl/binding.py", line 13, in <module> from cryptography.hazmat.bindings._openssl import ffi, lib ImportError: /usr/lib/python2.7/site-packages/cryptography/hazmat/bindings/_openssl.so: undefined symbol: pthread_atfork Adding CFLAGS_append = " -pthread " to the recipe: https://github.com/openembedded/meta-openembedded/blob/rocko/meta-python/recipes-devtools/python/python-cryptography_2.0.3.bb (or the include file). Will fix the problem and doesn't seem to hurt the other platforms where the issue doesn't occur (mips32el and mips32el-nf). See also: https://bugs.gentoo.org/630578
