cmakelists.txt fot C++ IDE
Hi all,
I want to work with simple gnuradio objects in a C++ IDE (e.g. Qtcreator)
using CMake build system.
I am running ubuntu 22.04 and gnuradio 3.10.11.0.
How can I write its cmakelists.txt?
For example, to just test these PMT lines:
#include // [...] pmt::pmt_t P = pmt::from_long(23);
std::cout << P << std::endl; pmt::pmt_t P2 = pmt::from_complex(0,1);
std::cout << P2 << std::endl; std::cout << pmt::is_complex(P2) <<
std::endl;
I add the following lines to its cmakelists.tx
# Find GNU Radio package, specifying required components
find_package(Gnuradio "3.10" REQUIRED COMPONENTS pmt) # Adjust the
version and components as needed
# Check if GNU Radio is found
if(Gnuradio_FOUND)
message(STATUS "GNU Radio found.")
message(STATUS "GNU Radio include dirs: ${Gnuradio_INCLUDE_DIRS}")
message(STATUS "GNU Radio libraries: ${Gnuradio_LIBRARIES}")
else()
message(FATAL_ERROR "GNU Radio not found!")
endif()
# Include directories for your project
include_directories(
${Gnuradio_INCLUDE_DIRS} # GNU Radio include directories
${CMAKE_SOURCE_DIR}/include # Your custom include directories
)
# Define the executable
add_executable(myproject ${SOURCES})
# Link the executable with GNU Radio libraries
target_link_libraries(myproject ${GNURADIO_LIBRARIES})
but it doesn't work.
I'd be grateful if someone help me write working cmakelists.txt.
Thanks!

The components are now available as CMake gnuradio::gnuradio-COMPONENT targets.

instead:
target_link_libraries(myproject gnuradio::gnuradio-pmt)
should do the trick.

Hi Ali,
since CMake is the default build system we use both for our OOT templates (as used by
gr_modtool) and by the C++ code generated throug GRC, I'd say:
just use the existing work as template.
What you're doing here is mixing modern CMake, i.e. a config/target-based method of
defining the compiler and linker properties of your compilation units, with manual
"include_directories" things. Probably not a great idea! If you compare that with what
`gr_modtool` generates in its lib/CMakeLists.txt, you'll find how we'd, as a project,
would recommend you do it.
Best,
Marcus

hier block location in 3.10.11
This isn't a serious issue but I'm curious. According to https://wiki.gnuradio.org/index.php/Hier_Blocks_and_Parameters, "For GNU Radio v3.10, the files will be created in the directory where the /.grc/ file is saved. Please create the /.grc_gnuradio/ directory and copy the /.py/ and /.yml/ files there:" However the associated hier block *.py and *.yml files appear in ~/.local/state/gnuradio. I copy them over to ~/.grc_gnuradio and all appears well. Is this the intended behaviour? Rick
Re: cmakelists.txt fot C++ IDE
Done! Big Thanks!
I just connected a "Signal Source" to a "Null Sink" in GRC, changed the
Option's "Output Language" to C++,
pushed "Generate" (F5), took a look at the generated CMakeLists.txt, and
found the answer.
Thanks!
