需要安裝的東西主要是codebocks與wxWidgets。

１，codebocks可以在圖形介面中安裝codebocks－IDE.

這個的安裝比較簡單，如果電腦中已安裝好gnu工具它會自動找出。這時已可以寫簡單的小程式了。

２，要用wxWidgets，主要是開發圖開介面應用，所以還需要安裝編緝介面元素的plugin。這個只能用命令安裝。

sudo apt-get update

sudo apt-cache search codeblocks

sudo apt-get install codeblocks-contrib

還能看到其它的一些codeblocks模組，用到時再去安裝吧。

３，wxWidgets用原始碼安裝，下載wxWidgets-3.0.4.tar.bz2http://www.wxwidgets.org/.

解碼到一個目錄。

./configure --with-x11
make

sudo make install

設定其動態庫目錄：

cd /etc/ld.so.conf.d/
sudo touch wxWidgets.conf
sudo gedit wxWidgets.conf  #增加其內容為/usr/local/lib
重新載入動態庫配置資訊： 
sudo ldconfig

錯誤處理

1,pangoxft找不到的錯誤，解決方法一是/configure --with-x11 --disable-unicode ，這個方法中文顯示有問題。再就是apt升級一下它。

這裡升級時用個問題，在中國的伺服器，和美國的可升級的最新版本是有差別的。有用官方支中國區升級伺服器，不能成功安裝。這就要改/etc/apt/sources.list換成如下內容：這個檔案我是在github上找到的。

2,codeblock不需要配置就應當可以用的。但網上有說法有一wx的變數在要codeblock的setting中設為wxWidgets的原始碼目錄。但我配和這個變數，再刪去一樣好用。

４，ubuntu用的是x11而不是gtk但gtk對中文的支援好一些，如果出問題可以試一下把wxWidgets編譯成用gtk.

/configure --with-gtk --disable-shared

--disable-shared在新電腦上安裝時，會用重新一一把需要更新庫。

 gtk也是要安裝的，安裝時會遇到依賴錯誤，這個錯誤也是原因最新軟體包找不到引起的。當然也可能是別的問題。換用美國的伺服器試一下。這個需要開通ipv6才好用。

用gtk,x11基本的中文都沒什麼問題。用codeblock新建的工程試一下。把它符成改一部分為中文編譯沒問題，但新編譯的程式中文顯示可能還是有問題。這個可以用程式碼解決。

bool sample2App::OnInit()中加入如下程式碼。
       //用中文的關鍵
           if ( setlocale (LC_ALL,"") == NULL ) {
                //(void) fprintf (stderr, "%s: cannot set locale.n",
                //program_name );
                exit (1);
        }

Ｘ１１與gtk的顯示視覺效果有一點差別。但影響不大。
