C++ OOT module porting from 3.8 to 3.10 cmake error

[Guillermo Lena]

Hello,

I have a OOT module in GNU Radio 3.8 I need to port to 3.10. In order to do that I thought I would just create a new module from my Ubuntu 22.04, where I have successfully installed GNU Radio 3.10 using gr-modtool. I have followed the C++ OOT module tutorial from the GNURadio wiki (https://wiki.gnuradio.org/index.php?title=Creating_C%2B%2B_OOT_with_gr-modtool). That way I created a new module with all the new folders and files where I copied the corresponding code from the block.h, block_impl.cc, block_impl.h and block.yml from 3.8 module. Then when I jump into the building step, after I do the cmake .. inside the build folder, I get the following output error:

CMake Error at /usr/lib/x86_64-linux-gnu/cmake/gnuradio/GrPybind.cmake:238 (message):

  Python bindings for csp_zmqhub_pdu.h are out of sync

Call Stack (most recent call first):

  python/satmisc/bindings/CMakeLists.txt:34 (GR_PYBIND_MAKE_OOT)

-- Configuring incomplete, errors occurred!

See also "/home/gnuradio/persistent-folder/gr-satmisc/build/CMakeFiles/CMakeOutput.log".

I belive this has nothing to do with the actual code that goes inside the block itself (at least not yet), but of course I could be wrong.

Any tips on how to approach this?

Thanks.
