I have a similar problem as described in
https://lists.gnu.org/archive/html/discuss-gnuradio/2015-05/msg00195.html.
When I try to run tests (with Python), I get:
*Traceback (most recent call last):*
* File "python/myblock.py", line 12, in <module>*
* from myproj.myproj_swig import mitigation_source*
* File "/home/user/gr/lib/python2.7/site-packages/myproj/myproj_swig.py",

* _mod = imp.load_module('_myproj_swig', fp, pathname, description)*
*ImportError: /home/user/gr/lib/libgnuradio-myproj-1.0.0git.so.0.0.0:
undefined symbol: _ZN3uhd11time_spec_tC1Eld*
I did add "UHD" to the line starting with "set(GR_REQUIRED_COMPONENTS" (in
my root CMakeLists.txt) so I get the output of
*Checking for GNU Radio Module: UHD*
*-- Checking for module 'gnuradio-uhd'*

*
*GNURADIO_UHD_FOUND = TRUE*
I also have in my lib/CMakeLists.txt file ${GNURADIO_ALL_LIBRARIES} in
both target_link_libraries() lists.
I have "#include <uhd/types/time_spec.hpp>" in my header file.
But for some reason, it doesn't seem to link gnuradio-uhd:
