Python --install-data

The attached recipe fails with the following output:

...

running "python setup.py" with command "build" and parameters ()
running build
...
phase `build' succeeded after 0 seconds
starting phase `check'
running "python setup.py" with command "test" and parameters ()

Apparently, install_data tries to write into the python directory, although
a different prefix is given; later, I also added the "--install-data"
configure flag, the behaviour is the same in both cases.

Does any of the python gurus understand the problem?

Perhaps you could check how that ‘install_data’ thing is implemented in
setup.py to see how it derives the .../share/icons directory name.
Maybe that will give clues as to how to fix it (maybe?).

(But really, it’d be best if the experts would chime in.  :-))

My 0.02¢,

If you don't add any flags, it will try to use the Python directory: this is
because of setup_other(), which uses sys.prefix. Now, I'm not a "Python guru"
(especially not when it comes to the associated build systems), but I think
setting "--prefix" should be enough. Apparently, it is not. I tried to replace
setup_other() by a dummy function that just does "return {}", and I was able to
install the package. Not sure it does what we want, though. I could find the
"aarddict.png" file in my ~/.guix-profile, FWIW.

The best thing to do might be to report this issue to the aarddict developers.
Either there's an issue in setup.py, or this is the expected behaviour and we'll
learn more about setuptools :)

WDYT ?

Indeed, the problem occurs also outside guix. I filed a bug report:
   https://github.com/aarddict/desktop/issues/30
As there is hardly any development activity going on, I just hope it will be
treated.
