Hi all,
I'm having right now problems with a implementation of a time tag in a
block that I'm writing. I'm basically writing a burst tagger with SOB, EOB
and TX_TIME tags. The first two are working, but the third (the one that
uses a UHD function), is giving me problems.
I recognized that the part that is not properly working is when I write
"uhd::time_spec_t". I even tried to create an arbitrary variable by writing
just "uhd::time_spec_t test;" in an arbitrary function and then ctest, and
then I notice that there is problems with that, as the output says:
" /$WORKING_DIR$/build/lib/libgnuradio-dyspan.so: undefined
symbol: _ZN3uhd11time_spec_tC1Ed"
Make and make install of my block run without any issue.
I have in the headers and body the necessary includes, such as <sys/time.h>
and <uhd/types/time_spec.hpp>. I also added the UHD module in the
CMakeList.txt file and it is found, as I can see this in the output:
-- Build type not specified: defaulting to release.
-- Boost version: 1.54.0
-- Found the following Boost libraries:

I sincerely don't know what am I missing. Maybe I'm skipping some linking
steps, but I don't know right now how to trace this. Any type of help will
be welcomed.
Thanks in advance for your opinions,
Nicolas
