This tutorial shows how to cross-compile the Embedded build of Qt 5.5 for Raspberry Pi 2. The Embedded build does not use the X11 server and instead displays the GUI directly using the Raspberry Pi framebuffer. We will show how to use a Raspberry Pi…

Compiling a kernel module for the raspberry pi 2 via Ubuntu host Normally compiling a kernel module for a linux distribution is rather straight forward, but on the raspberry pi however it's a little more involved. That's why in this article I am goin…

When we cross compiling coreutils, there is an problem of generating man pages, because the source script use the binaries generated by make process to produce man pages, but the cross compiled binaries cannot run on build machine. In order to resolv…

让QT/Embedded支持国际化 环境配置: Qt/Embedded ,在主机和目标板上存放路径都为:/root/qt-embedded-free- Qt/X11 3.3 (主要用到其中的lupdate,lrelease和lingust工具) .修改并重新编译应用程序,使之支持I18N 编辑程序入口文件,在QApplication对象声明之后添加: QTranslator translator; translator.load("pro_zh"); //假设你的qm文件名为pro_z…

一.元对象  元对象被称做是meta object.在运行时刻(runtime),能够提供对象的运行时信息.        在C++语言发展的早期,C++语言本身没有定义对象的运行时信息,如输出类的名称,父类的名称,判断对象的继承关系等等.虽然新的C++语言增加了RTTI,但还是不够的.这些信息在面向对象编程和调试程序过程中是非常有用的.因此不同的类库采取了不同的方式来扩展语言.         MFC的实现方式是宏定义:如           DECLARE_DYNAMIC,DECLARE_D…

ABSTRACT There are two main methods for building the kernel. You can build locally on a Raspberry Pi which will take a long time; or you can cross-compile, which is much quicker.There is an introduction about cross-compilation as follows. You need ub…

前言 上一篇我们讲了在linux环境下给树莓派安装系统及入门各种资料 ,今天我们更进一步,尝试在PI3上安装openCV开发环境. 博主在做的过程中主要参考一个国外小哥的文章(见最后链接1),不过其教程中有一个地方稍微有点问题,导致我入坑好久!这里也会着重说明下. 1.Expand filesystem 新安装系统之后,首要的工作就是扩大文件系统.因为,用SD卡安装完系统后一大部分空间实际是未被分配的: sudo raspi-config 选择7高级,然后选择“1. Expand File Sy…

Raspberry Pi's latest kernels and firmware, including Raspbian and NOOBS releases, now by default use Device Tree (DT) to manage some resource allocation and module loading. This change is to alleviate the problem of multiple drivers contending for s…
