Re: [Discuss-gnuradio] Important: New trunk dependency: GSL

[Robert McGwier]

In gnuradio-core,  there will be new filter bank technology introduced
that will use gsl to accomplish the debauchery of the indices in
compact readable form.  We are about to use gsl to compute discrete
wavelet transforms.  There are others but these suffice.

One could always replace the underlying routines with local ones that
are not bound to gsl.

The simple facts are that gnuradio cannot be all things to all people.
 It might come closer than almost anything else but it cannot run
without modification on all computing equipment from dspPic's to
Vertex 5's to Cell to x86_64 to OMAP3XXX !

I really like the OMAP with its ARM9, TI DSP chip and Neon SIMD math
chip and OpenGL acceleration hardware.  It is a worthy target of
effort.
