Cannot build OOT from macos

Hi!

I have been using gnuradio for a while on my macos M2, including the creation and compilation of out-of-tree modules or OOT.

Today, after a few months inactive, I tried ro re-compile my OOT blocks. Something must have been changed in the system during this time, since I cannot now compile.

I post the error message, and then my system configuration. (Sorry I do not know how to format code properly for the mailing list archives to print nicely)

I am working with Airspy modules. The whole setup was installed in my machine via conda/mamba, in a completely dedicated conda environment. This is all I have:

1. Create a conda environment

mamba create -n allaus

mamba activate allaus

mamba env config vars set LD_LIBRARY_PATH=~/miniforge3/envs/allaus // use DYLD_LIBRARY_PATH if on MacOS

mamba activate allaus

2. Install all required packages

mamba install -c conda-forge cmake pybind11 libusb boost libairspyhf airspyhf soapysdr-module-airspyhf gnuradio

3. build

cd allaus-gnuradio

cd gr-iri_arva_clean

mkdir build

cd build

cmake --install-prefix=~/miniforge3/envs/allaus ..

make -j5

affter which the reported error occurs.

With these exact steps I could compile my OOT modules some months ago. These modules were created following the gnuradio instructions here.

I tried to trace back the error to spdlog, with no luck. 

Any ideas ?

Thank you!
