在GTK下编译wxWidgets2.8.10错误的问题

在上文提到的在Linux下编译wxWidgets库的过程中出现报错。

方案：

wxWidgets版本：wxWidgets2.8.10

GTK版本：Ubuntu11.04

编译器：GCC4.5

报错的具体内容：

借助谷歌发现之前有人遇到过类似的问题，症结在于gtk+与wxWindgets2.8.10中共同定义了 GSocket。

修改gtk+显然不太合适，所以就改wxWidgets咯，修改一下wxWidgets的源代码：

位置是根目录下的src/gtk/gsockgtk.cpp

#include "wx/unix/gsockunx.h"

define和undef部分是新添加的，将GSocket重命名为GlibSocket就可以避免同名了。

重新编译，实测成功！
