Arduino Yun

[Andy Clark]

I'm trying to install cffi on the Linux/OpenWRT side of an Arduino Yun so that I can get requests[security] working.

My install log is as follows:

Collecting cffi>=0.8 (from cryptography>=0.7->pyOpenSSL->requests[security])
  Using cached cffi-0.9.2.tar.gz
    Complete output from command python setup.py egg_info:
    mips-openwrt-linux-uclibc-gcc: error trying to exec 'as': execvp: No such file or directory

        No working compiler found, or bogus compiler options
        passed to the compiler from Python's distutils module.
        See the error messages above.
        (If they are about -mno-fused-madd and you are on OS/X 10.8,
        see http://stackoverflow.com/questions/22313407/ .)

    ----------------------------------------
    Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-ZTXAdi/cffi


I'm trying to workout what's missing / incorrectly configured. Any suggestions as to what I need to install/build/configure?

I think I've actually got two different errors here.

Am I correct in thinking the reference to "as" is the GCC assembler?

Where is the -fhonour-copts likely to be hiding, as it does not seem to be in the cffi source? Any ideas what that does and if it's needed for cffi?

[Andy Clark]

I installed binutils and that got rid of my AS error. Just need to resolve the -fhonour-copts issue now.

[Andy Clark]

I could not work out where that -fhonour-opts setting was being passed in, I'm guessing it's somewhere deep in distutils. However I managed to find a newer GCC version (4.8.3) on the OpenWRT site http://downloads.openwrt.org/ which has got me a bit further

Install "python-dev", which you need for any Python module that
contains bits written in C.

Andy, did you ever get cffi installed?

How did you install python-dev stuff?

Thanks,

Matt

This is a problem best discussed on the general python-list mailing
list (https://mail.python.org/mailman/listinfo/python-list), or
googling around for "how do I install a Python package that uses C
extension modules". The answer depends on the platform you are on,
but on Linux (Debian family) it is "sudo apt-get install python-dev".


A bientôt,

Armin.

Hi Andy,

I've been on this for a couple of days. Did you make any progress on this?
