I successfully built the how-to-write-a-block example outside of
gnuradio-core. Now, I would like to implement my own version of
gr_file_source, and I was hoping to do it outside of gnuradio-core.
As a first step, I copied gr_file_source.* from core into a directory
structure similar to that used in the howto, and then changed all
occurrences of gr_file* to rad_file* and made the appropriate (?)
changes to configure.ac and all the Makefile.am.
However, on make, SWIG reports that it doesn't know anything about
gr_sync_block, which is inherited from rad_file_source. Here's what make
says:
make all-recursive

gr_sync_block.h is in /gnuradio/gr/include/gnuradio, which is in the
include path. Do I need a -L or something? Does anyone have any idea
what bone-headed thing I'm doing wrong? I've attached logs of configure
and make, along with my swig file.
Thanks,
