WxPython upgrade trouble on Ubuntu 8.04
in [wxWindows]

From: ladasky on 25 Jan 2010 06:18 Hello everyone, You know the old saying, "in for a penny, in for a pound." Several hours ago I posted this... http://groups.google.com/group/comp.lang.python/msg/0a86e792c674adc8 ....in which I described my desire to acquire Python 2.6 without upgrading my Ubuntu Linux installation from 8.04. Since Python 2.6 is not part of the Ubuntu 8.04 repository, I installed Python 2.6 manually. Things are a little messy right now, since invoking IDLE from the desktop still defaults to Python 2.5. But I'm getting there. At least I can access Python 2.6 from the command prompt, and SCIte also finds 2.6. Of course, I also have to reinstall all of the Python modules that I use on 2.6. I have succeeded with numpy and biopython, both installed manually. WxPython is giving me trouble, though. I visited wxpython.org and noted that wx version 2.8.10.1 fixes some important bugs that can occur when using Python 2.6. The instructions here... http://wiki.wxpython.org/InstallingOnUbuntuOrDebian ....allowed me to add the wxWidgets apt repository to the list of web sites that my Synaptic Package Manager checks for updates. It found wx 2.8.10.1 and auto-installed it. I got error messages from Python 2.5 until I also installed python-wxtools, wx2.8-i18n, libwxgtk2.8- dev, and libgtk2.0-dev as recommended on the web page mentioned above. Now "import wx" worked again, with no error messages, from Python 2.5. Installing wx on Python 2.6 is my ultimate goal, and here's where I'm stuck. I actually tried "import wx" from Python 2.6 first, and I got this result: >>> import wx Traceback (most recent call last): File "<stdin>", line 1, in <module> File "wx/__init__.py", line 45, in <module> from wx._core import * File "wx/_core.py", line 4, in <module> import _core_ ImportError: No module named _core_ I went back to Synaptic, said that I wanted to reinstall wx 2.8.10.1 -- but not really, as I then selected "download package files only." I received the tarball. The top-level folder has the wx binary stuff, which I believe is already installed. I selected the wxPython directory at the second level. Tried "python setup.py build", and after several minutes and dozens of warning messages, I finally got this fatal error: In file included from /usr/include/wx-2.8/wx/glcanvas.h:54, from contrib/glcanvas/gtk/glcanvas_wrap.cpp:2661: /usr/include/wx-2.8/wx/gtk/glcanvas.h: At global scope: /usr/include/wx-2.8/wx/gtk/glcanvas.h:47: error: GLXContext does not name a type /usr/include/wx-2.8/wx/gtk/glcanvas.h:124: error: ISO C++ forbids declaration of GLXFBConfig with no type /usr/include/wx-2.8/wx/gtk/glcanvas.h:124: error: expected ; before * token error: command 'gcc' failed with exit status 1 Worse -- NOW if I start Python 2.5, I get the same error message I got from 2.6. Now I'm stuck again. Any advice? Many thanks!

Any advice? Many thanks! Try re-posting to the wxPython mailing list. Someone there will know what the next step is. ------------------- Mike Driscoll Blog: http://blog.pythonlibrary.org PyCon 2010 Atlanta Feb 19-21 http://us.pycon.org/
