I have to install the sources for gpsd and I meet this error, what to do?

Question

Here are the error messages even though I have installed the python modules ( serial , matplotlib ... ) when I type the command : scons && scons check && scons udev-install

WARNING: gpsplot is missing required runtime module matplotlib
WARNING: ubxtool and zerk are missing optional runtime module serial
Ensure your PYTHONPATH includes /usr/local/lib/python3/dist-packages/

Answer 1

I just got the clue building gpsd.

Aw bad are messages to explain errors.. I did understand by reading the Sconscript

So to get the package just do

<sudo> apt install -y python3-matplotlib

then be explicit calling scons

scons target_python=python3

if you do not specify python version it uses by default python and so it will not find matplotlib (which is said by the error message gpsplot).

And same for QtNetwork it did not find because the pkgFind script was not able to get the version by itself, so you have to be explicit. I installed Qt5.

scons qt_versioned=5 target_python=python3

scons -h # minus

to see gpsd build options

I hope it helped
