I am trying to create a Project with Gnome Builder in Python. The documentation is very limited, but I think found out:
When you press the "build" button in Builder, it tries to build a flatpak and runs it. This works for the initial project stub. When i add a
import numpy
the project cannnot be run, because there is no numpy yet. I think this has to be added in the .JSON File. I also think the meson file is only for "collecting" the .py sources for the flatpak-builder. I followed the documentation on http://docs.flatpak.org/en/latest/python.html and created a module for numpy with the flatpak-pip-generator.
My .JSON file now looks like this:
{
"app-id": "de.gymlan.Plottler",
"runtime": "org.gnome.Platform",
"runtime-version": "3.32",
"sdk": "org.gnome.Sdk",
"command": "plottler",
"finish-args": [

"--filesystem=xdg-run/dconf",
"--filesystem=~/.config/dconf:ro",
"--talk-name=ca.desrt.dconf",
"--env=DCONF_USER_CONFIG_DIR=.config/dconf"
],
"cleanup": [
"/include",
"/lib/pkgconfig",
"/man",
"/share/doc",
"/share/gtk-doc",
"/share/man",
"/share/pkgconfig",
"*.la",
"*.a"
],
"modules": [
{
"name": "plottler",
"builddir": true,
"buildsystem": "meson",
"sources": [
{
"type": "git",
"url": "file:///home/ulrich/Projekte/Plottler"
}
]
},
{
"name": "python3-numpy",
"buildsystem": "simple",
"build-commands": [
"pip3 install --no-index --find-links=\"file://${PWD}\" --prefix=${FLATPAK_DEST} numpy"
],
"sources": [
{
"type": "file",
"url": "https://files.pythonhosted.org/packages/ac/36/325b27ef698684c38b1fe2e546e2e7ef9cecd7037bcdb35c87efec4356af/numpy-1.17.2.zip",

}
]
}
]
}
But the build fails with an error from git, which I don't understand:

(Last lines are german "child process failed")
I found out myself:
The section of the packages must not added in the main JSON-file, but in separate files. flatpak-pip-generator.py creates the resource files for the modules and theses files have to be added from the main JSON document. Mine now looks like that:
And the files "python3-*.json" reside the same directory. So all I had to do is calling
in the projects directory and add the generated files to the projects JSON file.
