ubuntu18.04,配以用wxWidgets编写linux小程序
需要安装的东西主要是codebocks与wxWidgets。
１，codebocks可以在图形界面中安装codebocks－IDE.
这个的安装比较简单，如果电脑中已安装好gnu工具它会自动找出。这时已可以写简单的小程序了。
２，要用wxWidgets，主要是开发图开界面应用，所以还需要安装编缉界面元素的plugin。这个只能用命令安装。
sudo apt-get update
sudo apt-cache search codeblocks
sudo apt-get install codeblocks-contrib
还能看到其它的一些codeblocks模块，用到时再去安装吧。
３，wxWidgets用源码安装，下载wxWidgets-3.0.4.tar.bz2http://www.wxwidgets.org/.
解码到一个目录。
./configure --with-x11
make
sudo make install
设置其动态库目录：
cd /etc/ld.so.conf.d/
sudo touch wxWidgets.conf
sudo gedit wxWidgets.conf #增加其内容为/usr/local/lib
重新加载动态库配置信息：
sudo ldconfig
错误处理
1,pangoxft找不到的错误，解决方法一是/configure --with-x11 --disable-unicode ，这个方法中文显示有问题。再就是apt升级一下它。
这里升级时用个问题，在中国的服务器，和美国的可升级的最新版本是有差别的。有用官方支中国区升级服务器，不能成功安装。这就要改/etc/apt/sources.list换成如下内容：这个文件我是在github上找到的。
2,codeblock不需要配置就应当可以用的。但网上有说法有一wx的变量在要codeblock的setting中设为wxWidgets的源码目录。但我配和这个变量，再删去一样好用。
４，ubuntu用的是x11而不是gtk但gtk对中文的支持好一些，如果出问题可以试一下把wxWidgets编译成用gtk.
/configure --with-gtk --disable-shared
--disable-shared在新电脑上安装时，会用重新一一把需要更新库。
gtk也是要安装的，安装时会遇到依赖错误，这个错误也是原因最新软件包找不到引起的。当然也可能是别的问题。换用美国的服务器试一下。这个需要开通ipv6才好用。
用gtk,x11基本的中文都没什么问题。用codeblock新建的工程试一下。把它符成改一部分为中文编译没问题，但新编译的程序中文显示可能还是有问题。这个可以用代码解决。
bool sample2App::OnInit()中加入如下代码。
//用中文的关键
if ( setlocale (LC_ALL,"") == NULL ) {
//(void) fprintf (stderr, "%s: cannot set locale.n",
//program_name );
exit (1);
}
Ｘ１１与gtk的显示视觉效果有一点差别。但影响不大。
