Oh, the swig file is missing a %template export for a vector of size_t. It probably doesnt know how to deal with the channel list in the stream_args_t class -- hence the error. Is that correct? If you use the uhd_swig.i from the master branch, does that 32-bit pmt swig error multiple exported types come up? Or perhaps did the %import statements resolve this? -josh > > _______________________________________________ > Discuss-gnuradio mailing list > Discuss-gnuradio@gnu.org > https://lists.gnu.org/mailman/listinfo/discuss-gnuradio > _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
