库 将经常用到的程序模块化，制作成库。库的概念给编程带来明显的好处，不需要因为要开发或修改一个小软件，就要重写、编译大量的源代码，降低了开发难度，节约了可观的时间。 程序编译成可执行程序的过程一般包括：预处理、编译、汇编和链接几个步骤。我们所说的库就是在链接过程中用到的（动态库的显式链接除外），对不同类型的库有不同的处理模式。 库常分为动态库（共享库）和静态库。链接阶段使用静态库的方式是从静态库中获取用到的程序并集成到目标程序中（静态地存在），以后使用程序的时候就不再需要到静态库中去找了。而与之相对，动态库则在链接过程中不集成到目标程序中去，使用时动态地加载。 静态库文件的后缀一般是 .lib、.a，动态库文件的后缀一般是 .dll、.s...
STM32 软件模板
创建文件目录如下： Doc 用于存放文档； Libraries 用于存放各种库，其中的 STM32Lib 是不可缺少的内核与标准外设的驱动库。原则上，所有的库都不要做任何修改，保持与原始发行状态一致。 MDK-ARM 是与 RVMDK 编译器相关的文件夹，存放工程文件、各种输出文件等； User 目录用于存放我们自己开发的代码 mcu 为 MCU 外设驱动程序文件夹； lib 为一些库程序的文件夹； bsp 为其他板载器件的驱动程序。 MDK 开发环境只支持一级组结构，所以组结构就是扁平化了的。一般包含 STM32Lib、Startup、User、Doc 等组。 把内核及标准外设的驱动（C 文件）加入 STM32Lib 组： Startup 为启动代码组，要从 .\Libraries\STM32Lib\CMSIS\CM3\DeviceSupport\ST\STM32F10x\startup\arm 文件夹选择一个。 将 main.c、配置、中断服务等文件加入 User 文件夹并加载到 User 组。 stm32f10x_conf.h 头文件在 stm32f10x.h 中通过判断有无 USE_STDPERIPH_DRIVER 宏定义而确定是否引用。 此外还需要配置工程，定义单片机系列（如定义 STM32F10X_CL）、选择使用标准外设驱动库 USE_STDPERIPH_DRIVER Include Paths 中配置所有需要引用的头文件所在目录 配置时钟晶体的频率 在需要操作内核或标准外设的地方直接引用库的头文件（stm32f10x.h）即可： 在编译的时候可以看到所有的库文件都被编译了，速度很慢，如果没有使用某个库文件，可以选择不编译它。 取消选择 Include in Target Build 即可。 在 C/C++ 选项卡中选中 One ELF Section per Function 选项可将用不到的函数排除在编译结果之外，从而减小生成程序的大...
搭建 Qt5.1.1 + VS2010 集成开发环境及 Qt 静态库的编译方法
1、下载 Qt SDK（Software Development Kit，即软件开发工具包）的安装包：Qt 5.1.1 for Windows 32-bit (VS 2010, 505 MB) http://download.qt-project.org/official_releases/qt/5.1/5.1.1/qt-windows-opensource-5.1.1-msvc2010-x86-offline.exe 该安装包中包含了 Qt Creator 2.8.1，使用的是官方编译好的动态库。 2、下载 VS2010 的 Qt 插件：Visual Studio Add-in 1.2.2 for Qt5 http://download.qt-project.org/official_releases/vsaddin/qt-vs-addin-1.2.2-opensource.exe 3、在 VS2010 中配置 Qt 3.1 选择 Qt 库： 3.2 打开一个 Demo 编译一下看看： 很炫的效果。 4、编译静态库 用动态库编译发布的软件需要打包一系列的 DLL 才能在没有 Qt 环境的电脑上运行，有时候会显得很麻烦，希望能够生成一个单文件的 exe 程序。这时就需要静态编译了，相应地需要静态库的支持。通过配置编译 Qt 的源代码来产生静态库： 4.1 下载 qt-everywhere-opensource-src-5.1.1 http://download.qt-project.org/official_releases/qt/5.1/5.1.1/single/qt-everywhere-opensource-src-5.1.1.zip 4.2 将源代码解压到非中文目录 D:\qt-everywhere-opensource-src-5.1.1\（举例） 4.3 编译配置 4.3.1 修改 qtbase\mkspecs\win32-msvc2012\qmake.conf 文件，将： QMAKE_CFLAGS_RELEASE = -O2 -MD QMAKE_CFLAGS_RELEASE_WITH_DEBUGINFO += -O2 -MD -Zi QMAKE_CFLAGS_DEBUG = -Zi -MDd 改为： QMAKE_CFLAGS_RELEASE = -O2 -MT QMAKE_CFLAGS_RELEASE_WITH_DEBUGINFO += -O2 -MT -Zi QMAKE_CFLAGS_DEBUG = -Zi -MTd 这样对于对 VC 的链接库也将静态编译。 4.3.2 在 Visual Studio 命令提示界面进入源码的 qtbase 目录 4.3.3 运行 configure 进行配置，配置包含 odbc、sqlite，跳过 webkit cd D:\qt-everywhere-opensource-src-5.1.1\qtbase configure -prefix C:\Qt\Qt5.1.1\5.1.1\msvc2010-static -confirm-license -opensource -platform win32-msvc2010 -debug-and-release -static -qt-sql-sqlite -qt-sql-odbc -plugin-sql-sqlite -plugin-sql-odbc -qt-zlib -qt-libpng -qt-libjpeg -opengl desktop -qt-freetype -no-qml-debug -no-angle -nomake tests -nomake examples -skip qtwebkit Usage: configure [options] Installation options: These are optional, but you may specify install directories. -prefix <dir> ......
