You can convert/demangle the symbol using the c++filt command

  c++filt _ZN2gr5howto10square2_ff4makeEv
  gr::howto::square2_ff::make()

Make sure that you have implemented square2_ff::make() function and then check 
the .so file for undefined symbols.

  cd /home/ubuntu/gr-howto/build/
  ldd -r ./lib/lib*.so
  objdump -TC ./lib/lib*.so | grep make

You can also attempt a clean rebuild (delete the build directory) or in case 
you have installed a previous version of your OOT module then try uninstalling 
it - run `make uninstall`

Regards,
Vasil
