On Ubuntu 18.04, you have to install pybind11 from source.
sudo apt-get purge pybind11-dev
git clone https://github.com/pybind/pybind11
cd pybind11
git checkout v2.4.3 -b tmp
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -DPYBIND11_TEST=OFF ../
make
sudo make install

Thanks much! That got me past the numpy error and landed me in a
pybind11 error:
-- Python checking for numpy - found
-- Python checking for pygccxml - found
CMake Error at CMakeLists.txt:334 (message):
pybind11 version 2.0.1 < 2.4
2.0.1 is the latest from 'apt-get install pybind11'. I saw some stuff
in the git 'issues' but not sure how to proceed.
I'm taking on building from source because of all the times (dozen?)
I've attempted installation of UHD and gnuradio, the only successful
ones are the ones obtained by building from source.

Hi Chad,
You'll find a fix here, along with a link to the relevant bug report:
https://github.com/gnuradio/gnuradio/pull/5256
It's an unanticipated problem with the older version of CMake used
with Ubuntu 18.04, but the fix will be in the next release.
Cheers,
Ryan

All:
I'm building gnuradio from source on an Ubuntu 18.04.6 system.
I'm using the instructions from:
https://wiki.gnuradio.org/index.php/InstallingGR#From_Source
When I get to the step:
# Note: In the following command, you can add
-DCMAKE_INSTALL_PREFIX=XXX to install GNU Radio into the PREFIX XXX;
if not specified, then the PREFIX is /usr/local. See other CMake
options in Common cmake flags.
cmake -DCMAKE_BUILD_TYPE=Release
-DPYTHON_EXECUTABLE=/usr/bin/python3 ../
I get an error relating to numpy:
-- User set python executable /usr/bin/python3
CMake Error at cmake/Modules/GrPython.cmake:101
(target_link_libraries):
Cannot specify link libraries for target "Python::NumPy"
which is not built
by this project.
Call Stack (most recent call first):
CMakeLists.txt:318 (include)
-- Configuring incomplete, errors occurred!
numpy is installed and I can 'import numpy' successfully in python3.
(In fact I had issued "apt-get install *numpy*" previously and it
was successful.)
I tried finding this error in my archive of gnuradio discussion-list
emails, but came up empty, as did my google search.
Any advice?
Thanks,
C
