Re: [Discuss-gnuradio] Make test failed

I followed the gnuradio wiki page commands to create a new block.

address@hidden:~/Desktop$ gr_modtool.py create howto

Module directory is "./gr-howto".

Done.

Use 'gr_modtool add' to add a new block to this currently empty module.

address@hidden:~/Desktop$ cd gr-howto/

address@hidden:~/Desktop/gr-howto$ gr_modtool.py add -t sync square_ff

Operating in directory .

GNU Radio module name identified: howto

I have attached the header file that is generated through gr_modtool. You can notice that the generated API is not included in the header file.

I added the API manually and called the sptr using API header to solve this problem.

Well, it should.
I must admit I bungled gr_modtool a bit while working on porting it to
3.6.4, but it should be in a working state now.

Can you please post the command you used to add the block and the header
that was generated?
