Hello Peter,
I'm not sure it's that simple.
Sorry for my quick and a bit oversimplified response. I did my first
build on an older version (3.20) where ubxtool was not built but present
in the repo root. I see now that in 3.23 gpsd have changed concept and
client/ubxtool.py.in is mangled through the build system to fill in some
stuff and produce the ubxtool script.
To me it looks like the recipe has bugs in python area, or my environment /
build is causing problems.
In the log.do_compile file I see messages which make me wonder:
Checking whether python program exists...no
Target Python doesn't exist - disabling Python.
python = False (default True): build Python support and modules.
GPS regression tests suppressed because socket_export or python is off.
It looks to me that everything Python specific is disabled.
Therefore I am missing on the target e.g. also the following file which should
be generated:
/usr/lib/python3.9/site-packages/gps/__init__.py
/usr/lib/python3.9/site-packages/gps/gps.py
Can anyone confirm this?
Confirmed!
The issue is that the package gpsd requires /usr/bin/python to be
present as described in the documentation
(https://gitlab.com/gpsd/gpsd/-/blob/master/build.adoc#user-content-quick-start).
This is not the case in Yocto when using python3native bbclass. As
described in the documentation it is possible to add a symlink called
/usr/bin/python to the python interpreter in the sysroot. You can do
this by adding:
ln -sf python3-native/python3 ${STAGING_BINDIR_NATIVE}/python
When scons finds /usr/bin/python the python packages are also built in
gpsd. Then you can continue to install and package ubxtool.
Best regards,
/Peter
