Installing in a different python instance

Green_Kobold · May 28, 2007, 3:57am

Hi all,

I am trying to use wxPython with SAGE (Software for Algebra and
Geometry Experimentation).

I do think that the problem is in this output I get when running setup.py:
cc1plus: warning: command line option "-Wstrict-prototypes" is valid
for Ada/C/ObjC but not for C++

Anyway, here goes some details of the journey:

SAGE uses python. And I found out that sage users really install 3rd
party python packages and use them normally on sage. Standard modules
are available and, for example, if I go like:

sage: import sys
sage: sys.path
['', '/media/kubold/home/ref/Desktop/packages/sage',
'/media/kubold/home/ref/Desktop/packages/sage/local/lib/python',
'/media/kubold/home/ref/Desktop/packages/sage/local/lib/python25.zip',
'/media/kubold/home/ref/Desktop/packages/sage/local/lib/python2.5',
'/media/kubold/home/ref/Desktop/packages/sage/local/lib/python2.5/plat-linux2',
'/media/kubold/home/ref/Desktop/packages/sage/local/lib/python2.5/lib-tk',
'/media/kubold/home/ref/Desktop/packages/sage/local/lib/python2.5/lib-dynload',
'/media/kubold/home/ref/Desktop/packages/sage/local/lib/python2.5/site-packages']

I am using Ubuntu 7.04 and 6.10 (multiboot). The problems are exactly the same.

---- First try: Appending python's sys.path to sage's python's sys.path

$ python
Python 2.5.1 (r251:54863, May 2 2007, 16:56:35)

import wx ##So wx is working, right?
import sys
sys.path

['', '/usr/lib/python25.zip', '/usr/lib/python2.5',
'/usr/lib/python2.5/plat-linux2', '/usr/lib/python2.5/lib-tk',
'/usr/lib/python2.5/lib-dynload',
'/usr/local/lib/python2.5/site-packages',
'/usr/lib/python2.5/site-packages',
'/var/lib/python-support/python2.5',
'/usr/lib/python2.5/site-packages/wx-2.6-gtk2-unicode']

When I append these directories (or just
'/usr/lib/python2.5/site-packages/wx-2.6-gtk2-unicode') to sage' path,
the output is:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.5/site-packages/wx-2.6-gtk2-unicode/wx/__init__.py",

    import _core_
ImportError: /usr/lib/python2.5/site-packages/wx-2.6-gtk2-unicode/wx/_core_.so:
undefined symbol: PyUnicodeUCS4_FromWideChar

Ok. This wxPython install is called from apt. It seem to be compiled
for UCS4-based Unicode support (as seems to be python's apt
compilation). And SAGE's python seems to use UCS2-based Unicode
support. Assuming that all this is right, I went though:

---- Second Try: building wxwidgets and wxpython from source with no
Unicode support, and installing it to sage's python.
I am using wxPython just to make a Panel with buttons and SpinCtrl.
Some sizers.. all in English (firstly in Portuguese.. but that's ok,
maybe next time), I should not need Unicode support. Dependencies
should be ok, because wxPython for gtk2.8 is installed with apt.

$ cd wxPython-src-2.8.4.0/
$ mkdir bld
$ cd bld
$ ../configure --prefix=/home/tatius/Desktop/packs/experimental

And I get this output on one of the last lines:

Should wxWidgets be compiled in Unicode mode? no

Great.

$ make
...
$ make install

Wonderful. /home/tatius/Desktop/packs/experimental is there and seems
to have wxwidgets installation.

Next:
sage -python calls sage's python. So:
/media/kubold/home/ref/Desktop/packages/sage/sage -python setup.py
build_ext --inplace
WX_CONFIG=/home/tatius/Desktop/packs/experimental/bin/wx-config
UNICODE=0

I received several error of the types:

and

warning: 'created2' may be used uninitialized in this function

You're on the right track but came to the wrong conclusion. An ansi build of wxPython will still use the Python Unicode API in order to translate unicode values to ansi to pass on to wxGTK. The root of the problem is which unicode option was used to build the Python that is used for the wxPython build. That needs to have the same unicode settings as the Python used for running wxPython. Since sage's Python is using ucs2 then the Python used for building wxPython also needs to use ucs2. So assuming that sage's Python has all the development bits installed too the answer is to just run wxPython's setup.py with sage's Python. wxGTK's and wxPython's unicode settings don't matter, they will always do the RightThing based on the mode Python was compiled in.

$ cd wxPython-src-2.8.4.0/
$ mkdir bld

I think that you'll be better off to just use the wxGTK from the APT repository and then just build a custom wxPython for sage. Just be sure you have the libwx*-dev packages installed.

Next:
sage -python calls sage's python. So:

You don't have the GL headers and/or -dev packages installed. You can bypass that part of the wxPython build by adding BUILD_GLCANVAS=0 on the setup.py command line.

You're on the right track but came to the wrong conclusion. An ansi
build of wxPython will still use the Python Unicode API in order to

problem is which unicode option was used to build the Python that is

ok, but if I enter wxPython and run setup.py:

You don't have the GL headers and/or -dev packages installed. You can
bypass that part of the wxPython build by adding BUILD_GLCANVAS=0 on the
setup.py command line.

I installed freeglut-dev and ok!

You didn't do the install. That would have put both the compiled
extension modules and the .py files into sage's site-packages dir in the
right place.

Actually i have done the .../sage setup.py install. But the same error
is there still. More accurate, the output is:

sage: import wx

I had to boot on an other linux install, so the wxwidgets installation
is now in /home/ref/exp2

I will continue on this, my work is stuck until I get this running.

Thanks for your help Robin. Any other ideas?

Hi,

Its done. With your explanation about usc2, usc4. I downloaded by apt
the required libs and then ran setup.py without those strange flags.
Thanks Robin, with your hints I could situate what I was doing in
relation to what had to be done. BTW. what whre these options doing:
"build_ext --inplace", and why was it keeping me from installing it to
my python?

cheers!

ok! thanks!

ok, but if I enter wxPython and run setup.py:
/home/ref/Desktop/packages/sage/sage setup.py build_ext --inplace

I got:

/wx-2.8-gtk2-unicode/wx/tools/XRCed/encode_bitmaps.py to encode_bitmaps.pyc

and sudo /home/ref/Desktop/packages/sage/sage setup.py build_ext --inplace

gave me the same error:

I installed freeglut-dev and ok!

Actually i have done the .../sage setup.py install. But the same error
is there still. More accurate, the output is:

sage: import wx

That would have put the extension modules into the wx dir in the source tree, which is one way to test without needing to install to site-packages, you just need to set PYTHONPATH correclty.

and why was it keeping me from installing it to
my python?

I'm not sure. It shouldn't have prevented the distutils install command from working.

Ok. Everything. But my SpinCtrl don't display initial texts as before.
For example:

wx.SpinCtrl(self,ID_SPIN,'numb of elements',(10,100), min=1, max=200)

was displaying 'numb of elements' before I set any value in it.

what can that be?

Which version were you using before? Does calling SetValue help?

I don't really recall and killed my previous install, but anyway,
wx.SpinCtrl(self,ID_SPIN,'numb of elements',(10,100), min=1, max=200)
Should be displaying the text 'numb of elements', or not? now I am
using wxwidgets2.8 apt packs and a wxpython build from a fresh
wxpython source.
SetValue only accepts integers here.

No, it looks like it is ensuring that the value displayed is within the range set for the control.

If you want to do something like that then you can use a textctrl and a spin button and then manage converting the spin events to changes in the textctrl.
