Hi, the problem comes from an error in the CMake module installed with Gnuradio 3.9.2. I turns out that it is working flawlessly with version 3.9.3.

To make the package compile with version 3.9.2 (the one in the official repo), the CMakeFiles.txt file must be patched adding these lines:

########################################################################
# PyBind11 Related
########################################################################

find_package(pybind11 REQUIRED)
execute_process(
    COMMAND "${PYTHON_EXECUTABLE}" -c
    "try:\n import numpy\n import os\n inc_path = numpy.get_include()\n if os.path.exists(os.path.join(inc_path, 'numpy', 'arrayobject.h')):\n  print(inc_path, end='')\nexcept:\n pass"
    OUTPUT_VARIABLE PYTHON_NUMPY_INCLUDE_DIR)

After switching to branch maint-3.9, I get the error

-- Python checking for pygccxml - not found
CMake Error at /usr/lib64/cmake/gnuradio/GrPybind.cmake:243 (pybind11_add_module):
  Unknown CMake command "pybind11_add_module".
Call Stack (most recent call first):
  python/bindings/CMakeLists.txt:46 (GR_PYBIND_MAKE_OOT)

Even when python-pygccxml is installed. (Maybe it needs the python2 version?)

You need to switch the source to the branch maint-3.9:

source=('git+git://github.com/bastibl/gr-foo#branch=maint-3.9')

(And in build(), I removed the manual checkout, since #branch=maint-3.9 in the source array already checks out that specific branch.)

Also, then consider setting the dependencies more precisely:

depends=('gnuradio>=3.9' 'gnuradio<3.10')

Thanks for maintaining!

The $pkgver of this package uses latest git commit hash in the beginning. This is not monotoneously increasing but erratic with respect to version number ordering.

Package version must be strictly monotoneously increasing.

So please change the versioning scheme accordingly. Try to see if there is some official upstream version; if so, use that first.

Then (or only), use somethign which is monotoneously increasing, i.e. git commit cound, for information sake followed by latest commit date. The git commit hash can then be added.

Don't forget to increment $epoch when changing versioning scheme.

Thanks for maintaining!

Fails to build for me with

Hi and thank you for maintaining this pkg! The build fails as the master branch targets a version of GNU radio (3.9) which is not available either in AUR or the standard pacman repos. Changing the git branch to "maint-3.8" fixes the bug; git patch output follows:
