Re: [Discuss-gnuradio] blks2.pfb_arb_resampler segfault

[Andrew Davis]

I have a C++ port of optfir waiting to be merged you could look at:
https://github.com/glneo/gnuradio-davisaf/tree/master/gnuradio-core/src/lib/general,
it's in there, its the gr_optfir*. It has a few bug-fixes from the
python code.
