Re: [Discuss-gnuradio] cross compiling (Swig issue?)

[Almohanad Fayez]

Chris, I'm a little confused by "I used SWIG 2.0.4 on the host"  I haven't used OpenWRT but the assumption is that you have a cross compiled swig on your host which you're linking against and have installed on your embedded target.  It sounds like either some library is not installed properly but again it can be an environmental variable issue.

Are you making packages via openwrt? Filesystem? Can you provide some more details?  The easy but loooong way to get gnuradio working on embedded platforms might be a native compilation .... Philip Balister might have more insight ... he always does :)

Hello all,

I've tried to build GNU Radio 3.6.0 for an embedded system running OpenWRT.
I cross compiled with OpenWRT's toolchain, but used Swig 2.0.4 on the host
system. When I try to run a GNU Radio program that requires Python, I get
the following error:

address@hidden:~# usrp_flex
Traceback (most recent call last):

   _mod = imp.load_module('_gnuradio_core_runtime', fp, pathname,
description)
ImportError: File not found

My first hunch is that I am missing environment variables, but I'm not
really sure. It could also be a problem with Swig, which is why I'm posting
this; I don't know much about this program. Any help would be greatly
appreciated, and thanks in advance for any help!

Regards,
Chris
