在Ubuntu上安装CodeBlocks碰到无法启动的问题，错误讯息如下，
codeblocks: relocation error: /usr/lib/libcodeblocks.so.0: symbol _ZN13wxAuiNotebook7SetFontERK6wxFont, version WXU_2.8.5 not defined in file libwx_gtk2u_aui-2.8.so.0 with link time reference
网路上找了很多解法来试，下面的解法才work!
（Linux的套件相依姓与本身作业系统的相容性问题真的不少）
原文讨论串CodeBlocks Forum
以下是节录Sowaco的文章.
Title: Re: I can't run Codeblocks
E Insert the "lgp203.free.fr" - Repository into sources.list.
Start an editor:
sudo nano /etc/apt/sources.list
Insert following lines, save and exit.
##CodeBlocks<br % the problems:
Remove all 'old' packages:
sudo apt-get remove build-essential gdb
sudo apt-get remove libwxgtk2.8-0 libwxgtk2.8-dev wx2.8-headers wx2.8-doc
sudo apt-get remove libwxgtk2.6-0 libwxgtk2.6-dev wx2.6-headers wx2.6-doc
sudo apt-get remove wx-common
sudo apt-get autoremove
Use synaptic, search for wx* lib's and remove them.
sudo synaptic
Insert the "lgp203.free.fr" - Repository into sources.list.

##CodeBlocks

deb-src http://lgp203.free.fr/ubuntu karmic universe
deb http://lgp203.free.fr/ubuntu karmic unstable
deb-src http://lgp203.free.fr/ubuntu karmic unstable
Update list.
sudo apt-get update
Import key for the repository.
wget -q http://lgp203.free.fr/public.key -O- | sudo apt-key add -
Again some cleanups.
sudo apt-get autoremove
Install everything.
sudo apt-get install build-essential
sudo apt-get install gdb
sudo apt-get install libcodeblocks0 codeblocks libwxsmithlib0 codeblocks-contrib
sudo apt-get install libwxgtk2.8-0 libwxgtk2.8-dev wx2.8-headers wx-common
Now, Codeblocks should start.
codeblocks
After these steps, everything works fine....
