Re: [Discuss-gnuradio] Question on how to derive a class in an out-of-tree module based on a gnuradio class

[Robert McGwier]

Zhe, every single developer who has ever written for GnuRadio runs into this particular swig necessity and searches like mad, certain it is done...

Congrats.

Hi Marcus, Martin and Bastian, 

Thanks for your help!

You are right, it's a linker error, the reason is absolutely what Martin mentioned that I didn't refer the header files I used i.e packet_header_default.h in my swig file. 

I checked Bastian's swig file and made this class working as expected!

Thanks again!

Best,

Zhe

arg, sorry! I had to #define DIGITAL_API and include packet_header_default.h

I think that I also had some problems with the swig bindings without those includes and defines.
