[Discuss-gnuradio] Error Linking UHD
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 *
*from myproj.myproj_swig import mitigation_source*
* File "/home/user/gr/lib/python2.7/site-packages/myproj/myproj_swig.py",

*ImportError: /home/user/gr/lib/libgnuradio-myproj-1.0.0git.so.0.0.0:

I did add "UHD" to the line starting with "set(GR_REQUIRED_COMPONENTS" (in
my root CMakeLists.txt) so I get the output of

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

Re: [Discuss-gnuradio] Error Linking UHD
I must admit this is surprising to me, as the line of code where
LIBS=... is printed is pretty integrally coupled to the line that
specifies what GNURADIO_ALL_LIBRARIES is. Maybe CMake got confused?
I know this is kind of a "haveyoutriedturningitoffandonagain" answer,
but have you tried completely rm'ing your build/ directory and letting
CMake run anew?

I've done "rm -rf build/*" and "pushd build; cmake ../; and make -j7; and
make install; popd" ~ 50 times since yesterday :)
Any suggestions for debugging it?

Re: [Discuss-gnuradio] Error Linking UHD
add a "message ()" directive that prints the GNURADIO_ALL_LIBRARIES
that is actually used in your lib/CMakeLists.txt. If that is wrong:
Move your OOT's cmake/Modules/* out of the way – I do not endorse the
fact that we're distributing copies of all the GNU Radio CMake scripts
with our OOT template, as these might outdate locally.
I must admit I don't have an OOT where I test gr-uhd linkage myself.
Best regards,
Marcus

Re: [Discuss-gnuradio] Error Linking UHD
The MESSAGE directive shows it should be ok - added to lib/CMakeLists.txt,
after the first target_link_libraries(), the line "MESSAGE(STATUS "DEBUG GR
LIBS: ${GNURADIO_ALL_LIBRARIES}")".
The output:
*-- DEBUG GR LIBS:
/home/user/gr/lib/libgnuradio-runtime.so;/home/user/gr/lib/libgnuradio-pmt.so;/usr/lib/liblog4cpp.so;/home/user/gr/lib/libgnuradio-filter.so;/home/user/gr/lib/libgnuradio-fft.so;/home/user/gr/lib/libgnuradio-uhd.so*
I moved away all cmake/ files and then put them back one-by-one until the
build succeeded, which meant I ended up removing:
D cmake/Modules/CMakeParseArgumentsCopy.cmake
D cmake/Modules/FindGnuradioRuntime.cmake
D cmake/Modules/GrMiscUtils.cmake
D cmake/Modules/GrPython.cmake
D cmake/Modules/GrSwig.cmake
D cmake/Modules/GrTest.cmake
D cmake/Modules/UseSWIG.cmake
but still no luck (the undefined symbol error still exists).
It might be worth to mention, the version I use is 3.7.11.1.

Re: [Discuss-gnuradio] Error Linking UHD
Hi,
I had maybe similar issues with gnuradio recently, and when I not only removed
the build folder but the whole gnuradio folder and did a new git clone, it
magically went through as if there never had been any issue :) Don't ask how
much time I wasted on this one :)))
