[Discuss-gnuradio] create a new block in gnuradio

[김무연]

 Hi i need your help guys

I am doing researching using gnu radio

However there are no blocks i needed to do research

And i got to know that to conduct the research i thought, i have to make my own blocks

So i followed some ways on the internet

But at some point it didn't work and i didn't understand why

Could you guys help me know the way to create blocks in gnu radio?

thanks
