[Discuss-gnuradio] Error: ‘pdu’ has not been declared

[Henning Bredenberg]

Hi list,


I created an OOT module "work" and tried to copy the functions of  
blocks from the standard library with additional test-outputs for a  
better understanding. The block "pdu_to_tagged_stream" is copied in an  
own block called "tagged". Via following commands in the build  
direction I should be able to use this block in GRC.

cmake ../
make
sudo make install
sudo ldconfig

Following error occurs when i run make:


~/gnuradio/gr-work/build$ make

tsb_tag_key);

[...more errors including "‘pdu’ has not been declared"...]

I tried several things but since I'm not a skilled programmer I can't  
figure out what to change.
Inserting "#include <gnuradio/blocks/pdu.h>" in the tagged.h file  
doesn't fix it.
Anyone who can help me with this? If needed, i can add more  
information about the code.


Best regards,
Henning
