Re: [Discuss-gnuradio] SWIG compilation speedup!

[Philip Balister]

I just got the USRP running with an EFIKA board and OSSIE SCA. I'm
using the usrp-0.12 tarball. I had to use a USB2.0 controller in the
PCI slot to work around the usrp USB full speed problems I am having.

I took a quick look at using openembedded to build gnu radio. Thet
already support most of the required dependencies, but I noticed fftw
is missing. When I am bored (heh) I'll see about adding fftw and
seeing if I can get gnu radio to build in cross environment.
