Re: [IBMiOSS] failure on installing cryptography

You need libffi packages to compile first : https://sourceware.org/libffi/

i use this script to compile :

===================================================================================================================================

#!/QOpenSys/pkgs/bin/bash

OBJECT_MODE=64

export CONFIG_SHELL=/QOpenSys/pkgs/bin/bash
export CONFIG_ENV_ARGS=/QOpenSys/pkgs/bin/bash

export CC=gcc
export CFLAGS='-maix64 -fPIC -D_AIX -D_AIX32 -D_AIX41 -D_AIX43 -D_AIX51 -D_AIX52 -D_AIX53 -D_AIX61 -D_AIX71 -D_ALL_SOURCE -DFUNCPROTO=15'
export CXX="g++ -maix64"
export CXXFLAGS=$CFLAGS

export F77=xlf
#export FFLAGS="-O -I/QOpenSys/pkgs/include"

export AR="ar -X64"
export NM="nm -X64"

export LD="ld -b64"
# for 32-bit applications
#export LDFLAGS='-L/QOpenSys/pkgs/lib -Wl,-blibpath:/QOpenSys/pkgs/lib:/usr/lib:/lib -Wl,-bmaxdata:0x80000000'
# for 64-bit applications
export LDFLAGS="-Wl,-brtl -Wl,-bexpall -Wl,-bbigtoc -Wl,-blibpath:/QOpenSys/pkgs/lib:/usr/lib:/lib:./src/elfobjs -Wl,-bmaxdata:0x80000000"

export PATH=/QOpenSys/pkgs/bin:/QOpenSys/pkgs/sbin:/usr/local/bin

./configure --prefix=/QOpenSys/pkgs --host=powerpc-ibm-aix6.1.0.0
make clean
make
make install

Trying to install the cryptography package on our IBM I and I get the following error from pip:

import _cffi_backend as backend
ImportError: Could not load module /QOpenSys/pkgs/lib/python3.6/site-packages/cffi-1.11.5-py3.6-os400-powerpc64.egg/_cffi_backend.so.
The local-exec model was used for thread-local
storage, but the module is not the main program.
Examine the .loader section header with the 'dump -Hv' command.


Any ideas. I found a link talking about the _thread storage class on AIX but I don't know enough to understand it.
