BUILD这个目录在本系列的上篇文章中我们仔细看过，内含各种平台的编译脚本，这里就不仔细说了。client这个目录下有如下比较让人眼熟的文件: mysql.cc, mysqlcheck.c, mysqladmin.cc,mysqlshow.c，等等，如果你编译一下就会发现那些眼熟的程序也出现了，比如mysql。明白了吧，这个目录就是那些客户端程序所在的目录。这个目录的内容也比较少，而且也不是我们阅...
PE格式的定义头文件winnt.h
Onlyone_1314的博客
02-23 1347
  PE格式定义的主要地方位于我们的头文件winnt.h，这个头文件中几乎能找到关于PE文件的所有定义。   在很多编译器、调试器中都会带有这个头文件，如VC++6.0、codeblocks、Ollydbg等，在自己的电脑上一搜就有好多个。 整个的头文件winnt.h代码太长了，文章放不下来，其中PE文件格式主要定义在image format部分： 这部分的代码： // // Image Format // #ifndef _MAC #include "pshpack4.h"

嵌入式软件工程师的自我修养: Cortex-M3 ARM代码编译，链接与启动过程深度分析
zhuwade的博客
12-15 3568
本篇文章以武汉杰开科技的汽车级MCU芯片AC7811为硬件平台，使用GNU GCC作为开发工具。详细分析Compile 、Link 、Loader的过程以及Image(二进制程序)启动的详细分析。整个过程分析涉及到RW可读写DATA段从Flash到Mem的Copy，BSS段的初始化，Stack和Heap的初始化，C库函数移植、利用Semihosting 实现基本的IO等内容。基本可以让你从更深刻的层面理解源码->编译->链接->运行的整个过程。
