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
