Forum: GNU Radio Make test failed

Hello everyone,

I am trying to build my own block using gr_modtool.py. But When I run 
make
test its gives me an error.

Well, it says the symbol is missing: undefined symbol:
_Z20howto_make_square_ffv*

So this is something declared in a header file but not exposed by your
library. You probably need to implement howto_make_square_ffv, or make
sure the declaration in the header file has the proper API export macro.

Thanks Josh. It worked. Apparently, the gr_modtool.py is not including 
the
API in the header.

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?

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

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

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.

Ah OK, you're using an old version. I recommend updating.
