Hi all guys,

i have encountered a new problem which was not present before. I have my
old GR module (out of tree) for years. Yesterday I wanted to change
something and couldn't build it cause of the linker error.

libgnuradio-TMS.so: undefined reference to
`gr::blocks::file_sink_base::file_sink_base(char const*, bool)'
libgnuradio-TMS.so: undefined reference to
`gr::blocks::file_sink_base::~file_sink_base()'
libgnuradio-TMS.so: undefined reference to
`gr::blocks::file_sink_base::do_update()'

I know that before, I had similar error on some other machine, so I added
lines:

set(GR_REQUIRED_COMPONENTS CORE BLOCKS)
find_package(Gnuradio "3.6.5.1")

in my top CMakeLists.txt file but unfortunately nothing changed. I am sure
that everything is there, but can't figure out why it can't find it.

Cheers and thanx,
