linux trusty panda3d 1.9.2 issue during p3d execution : wx failed to choose a font

[Philippec]

PC ubuntu trusty 14.04.4 LTS
Ubuntu panda3d1.9_1.9.2~trusty_amd64.deb.

1/ I package the program below : /usr/bin/packp3d -o /home/philippe/gameeditor-svn/code/test/wx/testWX.p3d -d /home/philippe/gameeditor-svn/code/test/wx -m testWX.py -r wx -r morepy -D

testWX.py:

import wx
from direct.showbase.ShowBase import ShowBase
class MyApp(ShowBase):
    def __init__(self):
        ShowBase.__init__(self)
        self.accept('a', self.oGui)

    def oGui(self):
        app = wx.App()
        window = wx.Frame(None, title = "wxPython Frame", size = (300,200))
        panel = wx.Panel(window)
        label = wx.StaticText(panel, label = "Hello World", pos = (100,50))
        window.Show(True)
        app.MainLoop()
app = MyApp()
app.run()

2/ I execute the p3d program : /usr/bin/panda3d /home/philippe/gameeditor-svn/code/test/wx/testWX.p3d.
When panda3d screen is displayed : I use the keyboard 'a' in order to display a wx window => the text "Hello World" is replaced by squares and I got the following error messages in the terminal windows:

....
Fontconfig error: "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 70: non-double matrix element
Fontconfig error: "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 70: non-double matrix element
Fontconfig warning: "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 78: saw unknown, expected number

(p3dpython:17132): Pango-CRITICAL **: No modules found:
No builtin or dynamically loaded modules were found.
PangoFc will not work correctly.
This probably means there was an error in the creation of:
  '/etc/pango/pango.modules'
You should create this file by running:
  pango-querymodules > '/etc/pango/pango.modules'

(p3dpython:17132): Pango-WARNING **: failed to choose a font, expect ugly output. engine-type='PangoRenderFc', script='latin'

On the WX panel the text "hello world" is replaced by squares

[Philippec (cainphilippe)]

on windows the text is displayed properly

[rdb (rdb)]

I suspect there's an important environment variable that is not being propagated by the Panda3D Runtime.

Please print out the environment variables inside the application (using os.environ) and the environment variables outside of the application for comparison.

[Philippec (cainphilippe)]

Hello rdb

In this post he python environment variables are printed in 2 cases : python and panda3D execution.

Below you will find the environment variables when it is launched with python, the display in wx is OK

.....$ python ./testWX.py

Known pipe types:
  glxGraphicsPipe
(all display modules loaded.)

packp3d is no longer supported in 1.10 (in favour of the new setuptools-based deployment system), so I'm closing this. Please file an issue on GitHub if the issue still persists with deploy-ng.
