I built a new VM from zero. Ubuntu 20.04 apt install build-essential apt install git apt install cmake apt install python3-pip pip3 install pygccxml build, install pybind11 from 2.4.3 tarball setup gnuradio repository to releases apt install gnuradio This gives gnuradio 3.9.1.0
git-cloning both Ron's gr-iqlevels and my gr-hpsdr, going through cmake, make, sudo make install, sudo ldconfig yields exactly the same results as before: the gr:sync_block (gr-iqlevels) or the gr::block (gr-hpsdr) are not imported. -- Tom, N5EG On Sun, May 9, 2021 at 11:44 AM Tom McDermott <tom.n...@gmail.com> wrote: > Hi Ron - thank you for sending me the link to your 3.9 gr-iqlevels module ! > It builds and installs OK, but when trying to run it gives me the same > type of error as my own module: > > Note: cmake .. -DCMAKE_INSTALL_PREFIX=/usr was used for for gr-iqlevels > > $ python3 > Python 3.8.5 (default, Jan 27 2021, 15:41:15) > [GCC 9.3.0] on linux > Type "help", "copyright", "credits" or "license" for more information. > >>> import gnuradio > >>> import iqlevels > Traceback (most recent call last): > File "<stdin>", line 1, in <module> > File "/usr/lib/python3/dist-packages/iqlevels/__init__.py", line 18, in > <module> > from .iqlevels_python import * > ImportError: generic_type: type "iqlevels" referenced unknown base type > "gr::sync_block" > >>> > > And when run from GRC: > > Traceback (most recent call last): > File "/home/tom/Desktop/iqlevels.py", line 142, in <module> > main() > File "/home/tom/Desktop/iqlevels.py", line 120, in main > tb = top_block_cls() > File "/home/tom/Desktop/iqlevels.py", line 81, in __init__ > self.iqlevels_iqlevels_0 = iqlevels.iqlevels(samp_rate, 1) > AttributeError: type object 'iqlevels' has no attribute 'iqlevels' > > > So it appears there is something wrong or misconfigured in my system. > I am baffled as to what that might be. > > Ubuntu 20.04 > Gnuradio 3.9.0.0 > Python 3.8.5 > Cmake 3.16.3 > GCC 9.3.0 > pygccxml 2.1.0 installed using pip3 > pybind11-2.4.3 installed from tarball according to the OOT 3.9 instructions > pybind11 build, cmake, make, make install by the above directions. > it put the various pybind headers into /usr/local/include/pybind11/ > > Is there some other configuration, path, or other thing that needs to be > setup? > > -- Tom, N5EG > > > > >
