I’m building wxPython 3.0.0 on Ubuntu 13.10 using Python 2.7.6 via pyenv. Going through the standard CheckInstall instructions, the only change I made was to specify --pkgversion=3.0.0 instead of --pkgversion=2.9.4 when installing wxWidgets. This generates wxwidgets_3.0.0-1_i386.deb.
When the time comes to build wxPython itself, I run the checkinstall command, and after a long while I get this error:
Selecting previously unselected package wxpython.
(Reading database … 178101 files and directories currently installed.)
Unpacking wxpython (from …/wxpython_3.0.0-1_i386.deb) …

Errors were encountered while processing:

I’m not really sure why this error is occurring. Any help would be appreciated. By the way, when I try the installation again, do I have to do the wxPython checkinstall command again, or can I just run sudo dpkg -i wxpython_3.0.0-1_i386.deb? The checkinstall instructions don’t seem to include that command for wxPython 3.0.0, only wxPython 2.9.
Did you check the instructions for wxPython 3?
There is a specific section:
http://wiki.wxpython.org/CheckInstall#wxPython_3.0.0
I could compile and install it without issues on Ubuntu 13.10.
The only incomplete topic is to identify all of the dependencies versions (–requires parameter), you can check the required ones for wxPython 2.8 plus some new libs.
Looking at the error, maybe you installed it twice (or with other method beside checkinstall).
I should try remove all the installed files and packages, and then start over with a clean install.
Let me know if I can be of any further help

Thanks for replying. The instructions seemed to want me to build wxWidgets, then wxPython, but apparently that’s not the case, and that’s why I got the error. Or maybe you are supposed to build wxWidgets first, but only on wxPython 2.9? In any case, I actually started fresh on a copy of the operating system which had never tried to install wxPython before, installed python-wxversion using apt-get, and build wxPython using checkinstall. This seemed to work, but actually importing it failed:
import wx
Traceback (most recent call last):
File “”, line 1, in
File “wx/init.py”, line 45, in
from wx._core import *
File “wx/_core.py”, line 4, in
import core
ImportError: No module named core
There are a number of “wx” folders wxPython seems to have created, and presumably one of them is in my path somewhere and it’s the wrong one. To fix this, I added
/usr/local/lib/python2.7/dist-packages
at the start of my PYTHONPATH. (That directory contains both wx and wx-3.0-gtk2 directories, and wx-3.0-gtk2 has another subdir called wx inside it.)
That fixes that error, but I get this one instead:
import wx
Traceback (most recent call last):
File “”, line 1, in

import core
ImportError: libwx_gtk2u_adv-3.0.so.0: cannot open shared object file: No such file or directory
This baffles me. The only libwx_gtk2u_adv-3.0.so.0 file I have anywhere is back in the directory I downloaded and extracted from SourceForge when I was building wxPython, in the bld subdir: wxPython-src-3.0.0.0/bld/lib

Update: Previously, I had run only the
sudo checkinstall -y --pkgname=wxpython --pkgversion=3.0.0 ... ... ...
command. The wxPython 3.0.0 instructions do not ask me to run
sudo dpkg -i wxpython_3.0.0-1_i386.deb
afterwards, but if I now do that even though I wasn’t asked to, then wxPython actually does install the missing libwx_gtk2u_adv-3.0.so.0 file it complained about in my last post to /usr/local/lib. I can then add this directory to LD_LIBRARY_PATH and that fixes my previous error. But then I get this error!

Yeah, my version of Python didn’t use --enable-unicode=ucs4, that shouldn’t matter since I compiled wxPython by hand – shouldn’t wxPython have used the same (presumably UCS2) as the pyenv-provided version of Python it was built with?
Note that I get this error regardless of whether I’m using the
/usr/local/lib/python2.7/dist-packages/wx
or
/usr/local/lib/python2.7/dist-packages/wx-3.0-gtk2/wx
installation, by adding its respective parent dir to PYTHONPATH. I tried them separately. (I don’t know why building wxPython created both directories, and they both existed before running the new dpkg command.)

I undid my previous step (the call to sudo dpkg -i wxpython_3.0.0-1_i386.deb) and redid the single wxPython checkinstall command, followed by sudo ldconfig.
This no longer gives me the .so error, but I once again get the

Going back over your previous email, you seem to want me to set LD_LIBRARY_PATH and PYTHONPATH to specific locations within the extracted tarball from SourceForge, rather than the locations in /usr/local/lib/python2.7 that the wxPython installation created. I tried using your versions of these environment variables, but I get this error when I do so:

Here is what I did to install from source
I downloaded the latest source code, which at the time was located at:
http://downloads.sourceforge.net/wxpython/wxPython-src-3.0.0.0.tar.bz2
While I was downloading the source code I installed the dependencies which since I am using 12.04 are:
dpkg-dev
build-essential
swig
python2.7-dev
libwebkitgtk-dev
libjpeg-dev
libtiff-dev
ubuntu-restricted-extras
freeglut3
freeglut3-dev
libgtk2.0-dev
libsdl1.2-dev
libgstreamer-plugins-base0.10-dev
After the source code was finished downloading I navigated to the directory it downloaded to and ran:
tar -xvzf wxPython-src-3.0.0.0.tar.bz2
Then:
cd wxPython-src-3.0.0.0/wxPython && python build-wxpython.py --build_dir=…/bld --install
Grabbed a cup of coffee and a sandwich as my laptop took a bit. I didn’t receive any further errors and I can use wxPython 3.0.0.0 with no issues. I have quite a few -dev packages already installed due to me compiling other programs and modules from source so your mileage may vary.

Thanks for replying. The instructions seemed to want me to build wxWidgets, then wxPython, but apparently that’s not the case, and that’s why I got the error. Or maybe you are supposed to build wxWidgets first, but only on wxPython 2.9? In any case, I actually started fresh on a copy of the operating system which had never tried to install wxPython before, installed python-wxversion using apt-get, and build wxPython using checkinstall. This seemed to work, but actually importing it failed:

I undid my previous step (the call to sudo dpkg -i wxpython_3.0.0-1_i386.deb) and redid the single wxPython checkinstall command, followed by sudo ldconfig.

The only incomplete topic is to identify all of the dependencies versions (–requires parameter), you can check the required ones for wxPython 2.8 plus some new libs.
Looking at the error, maybe you installed it twice (or with other method beside checkinstall).
I should try remove all the installed files and packages, and then start over with a clean install.
Let me know if I can be of any further help

I’m building wxPython 3.0.0 on Ubuntu 13.10 using Python 2.7.6 via pyenv. Going through the standard CheckInstall instructions, the only change I made was to specify --pkgversion=3.0.0 instead of --pkgversion=2.9.4 when installing wxWidgets. This generates wxwidgets_3.0.0-1_i386.deb.
When the time comes to build wxPython itself, I run the checkinstall command, and after a long while I get this error:

I’m not really sure why this error is occurring. Any help would be appreciated. By the way, when I try the installation again, do I have to do the wxPython checkinstall command again, or can I just run sudo dpkg -i wxpython_3.0.0-1_i386.deb? The checkinstall instructions don’t seem to include that command for wxPython 3.0.0, only wxPython 2.9.

Thanks for replying. The instructions seemed to want me to build wxWidgets, then wxPython, but apparently that’s not the case, and that’s why I got the error. Or maybe you are supposed to build wxWidgets first, but only on wxPython 2.9? In any case, I actually started fresh on a copy of the operating system which had never tried to install wxPython before, installed python-wxversion using apt-get, and build wxPython using checkinstall. This seemed to work, but actually importing it failed:

at the start of my PYTHONPATH. (That directory contains both wx and wx-3.0-gtk2 directories, and wx-3.0-gtk2 has another subdir called wx inside it.)That fixes that error, but I get this one instead:

I undid my previous step (the call to sudo dpkg -i wxpython_3.0.0-1_i386.deb) and redid the single wxPython checkinstall command, followed by sudo ldconfig.
This no longer gives me the .so error, but I once again get theImportError: /usr/local/lib/python2.7/dist-packages/wx/core.so: undefined symbol: PyUnicodeUCS4_FromWideChar

Going back over your previous email, you seem to want me to set LD_LIBRARY_PATH and PYTHONPATH to specific locations within the extracted tarball from SourceForge, rather than the locations in /usr/local/lib/python2.7 that the wxPython installation created. I tried using your versions of these environment variables, but I get this error when I do so:

I believe you would want to add the directory where the freshly compiled wxPython is currently located. Someone please correct me if I am incorrect.
For example:export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/path/to/compiled/wx
The only reason I say this is that I ran into the error:
libwx_gtk2u_adv-3.x.so.0: cannot open shared object file: No such file or directory
And resolved it by adding:
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/lib
But again I could be incorrect about this and would appreciate it if someone could let me know if I’m right or wrong.

Here is what I did to install from source
I downloaded the latest source code, which at the time was located at:

While I was downloading the source code I installed the dependencies which since I am using 12.04 are:
dpkg-dev
build-essential
swig
python2.7-dev
libwebkitgtk-dev
libjpeg-dev
libtiff-dev
ubuntu-restricted-extras
freeglut3
freeglut3-dev
libgtk2.0-dev
libsdl1.2-dev
libgstreamer-plugins-base0.10-dev
After the source code was finished downloading I navigated to the directory it downloaded to and ran:
tar -xvzf wxPython-src-3.0.0.0.tar.bz2
Then:
cd wxPython-src-3.0.0.0/wxPython && python build-wxpython.py --build_dir=…/bld --install
Grabbed a cup of coffee and a sandwich as my laptop took a bit. I didn’t receive any further errors and I can use wxPython 3.0.0.0 with no issues. I have quite a few -dev packages already installed due to me compiling other programs and modules from source so your mileage may vary.

About the errors, maybe you need to run ldconfig to update the cache:

Note that you don’t need to compile wxWidgets by hand, for wx3 now just run build-wxpython.py
python build-wxpython.py --build_dir=…/bld
And checkinstall should install it per default as using the --install parameter
IFAIR it builds both wxPython and wxWidgets, so that’s why there is only a package now created by checkinstall, and not two as with previous versions.
Once build, you can check it is working changing PYTHONPATH and LD_LIBRARY_PATH
export LD_LIBRARY_PATH=…/bld/lib
export PYTHONPATH=…/wxPython
cd …/wxPython/demo

Glad you were able to resolve the issue and get wxPython 3.0 working. I found that some versions / distros of Linux are using both Python 3.x and 2.7.x or at least including both. So I did a quick Google search and found, as well as tested another possible solution. Instead of typing sudo python at the beginning using sudo python2.7 worked for me. I tested this with an Ubuntu 13.10 Virtual Machine which has both Python 3 and 2.7.x installed.

This no longer gives me the .so error, but I once again get the
ImportError: /usr/local/lib/python2.7/dist-packages/wx/core.so:
undefined symbol: PyUnicodeUCS4_FromWideChar
or
ImportError:
/usr/local/lib/python2.7/dist-packages/wx-3.0-gtk2/wx/core.so:
undefined symbol: PyUnicodeUCS4_FromWideChar
error when I try to import wx in Python.
That can happen if the Python you run with is not the same Python you
built with, and they have different unicode build settings.–

I realized that calling
sudo checkinstall … python build-wxpython.py --build_dir=…/bld --install
was using my system version of python due to the “sudo”, so I made a symlink to my pyenv version called 2.7.6 and used that version instead of just “python” in the above command.This automatically installs wxPython to the proper pyenv directory and lets me import wx in my pyenv version of Python without modifying PYTHONPATH or LD_LIBRARY_PATH, but I still get Unicode errors:
import wx
Traceback (most recent call last):
File “”, line 1, in
File “/home/USERNAME/.pyenv/versions/2.7.6/lib/python2.7/site-packages/wx-3.0-gtk2/wx/init.py”, line 45, in
from wx._core import *
File “/home/USERNAME/.pyenv/versions/2.7.6/lib/python2.7/site-packages/wx-3.0-gtk2/wx/_core.py”, line 4, in
import core
ImportError: /home/USERNAME/.pyenv/versions/2.7.6/lib/python2.7/site-packages/wx-3.0-gtk2/wx/core.so: undefined symbol: PyUnicodeUCS4_FromWideCharSo somehow, even when wxPython is installed normally right into my pyenv dir using my pyenv version of Python, it doesn’t use the proper Unicode settings.
