I'm migrating an OOT module from GNU Radio 3.7 to 3.8.1.
I followed the instructions on
https://wiki.gnuradio.org/index.php/GNU_Radio_3.8_OOT_Module_Porting_Guide.
When running my app, I get:
*ImportError: /home/myuser/gr/as/lib/libgnuradio-myproject.so.1.0.0git:
undefined symbol:
_ZN2gr6filter6kernel14fft_filter_cccC1EiRKSt6vectorISt7complexIfESaIS5_EEi*
And verifying with ldd, I see libgnuradio-filter does not exist at the
dependency list of the compiled .so.
In *myproject/CMakeLists.txt*,
I have:
*find_package(Gnuradio "3.8" REQUIRED COMPONENTS blocks fft filter)#make
sure our local CMake Modules path comes firstlist(INSERT CMAKE_MODULE_PATH
0 ${CMAKE_SOURCE_DIR}/cmake/Modules)include(GrVersion)*
The same source code worked in GNU Radio 3.8 where the CMakeLists.txt file
contained:
*set(GR_REQUIRED_COMPONENTS RUNTIME FILTER)find_package(Gnuradio "3.7.2"
REQUIRED)list(INSERT CMAKE_MODULE_PATH 0
${CMAKE_SOURCE_DIR}/cmake/Modules)include(GrVersion)*
And the compiled .so file indeed referred to libgnuradio-filter.
I assume there's some mistake in the CMakeLists.txt file that causes the
compiled shared object not to link to libgnuradio-filter, but the above is
based on the module porting guide, so any pointer will be appreciated.
