Frederick,

You will have to recompile and reinstall, but not everything. If you
are modifying a single block, you can just rebuild from that
components directory. You want to do the entire component to make sure
SWIG is initiated again to rebuild the Python interface. But this is
much quicker than rebuilding from the top source directory that would
walk through all directories (it won't rebuild them, but the walking
takes time).

So if you are changing a block in gr-digital, you can just:

cd gr-digital
make
make test (or ctest)
sudo make install
