Howdy.

Thank you for looking at this - 

Sorry for the late reply, been following https://wiki.gnuradio.org/index.php?title=GNU_Radio_4.0

this on a custom built linux setup with a working gnuradio 3 install .

adding any new packages requested by gnuradio4 as encountered - perhaps i've missed something along the way...

cmake --preset dev
cmake --build --preset dev
source build/dev/activate.sh  

cmake --build --preset dev --target check

these all worked without any error, test worked too - 

note: source build/dev/activate.sh set LD_LIBRARY_PATH such that it causes path warning about dir2 need to be set before dir1 - it make no difference for build error 

cmake --preset full
cmake --build --preset full 

attached is a build log

Hi Steve,

Thank you for sharing this - would you be able to add a bit more detail on your setup and how you are kicking off the build.  Also would be good to add as a github issue here: https://github.com/gnuradio/gnuradio4/issues

Thanks!

Josh
