Ubuntu14.04 交叉编译Qt-creator

1. 下载Qt-creator 的源码：

     链接：http://download.qt.io/official_releases/qtcreator/

2.  进入源码目录编译：

$ qmake qtcreator.pro$ make....... ../3rdparty/botan/botan.cpp:46220:21: fatal error: cpuid.h: No such file or directorycompilation terminated.make[3]: *** [.obj/debug-shared/botan.o] Error 1

这个错误貌似每个qt-creator 版本编译都会有， 你需要给该源码打一个patch。

Patch 的内容如下：

将该Patch 内容copy 到你的本地文件， 例如我们的文件为qt-issue.patch。

3. 打patch 后重新编译， 顺利通过编译！
