Re: [Discuss-gnuradio] error when calling method of base class block

[Nemanja Savic]

Hello,

well after a lot of digging in the mailing list I added this into my swig.i file:

%include "gnuradio/blocks/file_sink_base.h"

and I also added this into my CMakeLists.txt:

set(GR_REQUIRED_COMPONENTS BLOCKS)

It turned out that only first change is required.

Best and hope that this will help somebody in the future.

What do your swig file changes look like?
