操作系统实验报告_ucore_lab1

在大三上学期接触了操作系统这门课程，经过了小半个学期的理论讲解，我对操作系统的局部有了粗浅的了解。 紧接而来的这个实验是清华大学的操作系统实验课程，有一定难度，需要去学习很多课本中没有详谈的问题，需要通过自己的一次次尝试去了解操作系统开发实验环境，进一步熟悉命令行方式的编译、调试工程，同时还要求我们熟悉C语言编程和指针的概念。 实验环境配置 本次实验需要在LINUX环境下完成。 实验指导书中给出了...

GCC的--wrap是一个链接器选项，假如我们要编译的源文件为main.c，编译命令如下： gcc main.c -Wl,--wrap=func -o main.elf 有以下效果： 如果符号func没有（在当前源文件）定义，就链接到__wrap_func 如果符号__real_func没有（在当前源文件）定义，就链接到func 举例如下： /* a.c */ #include <stdio.h> extern int foo(); extern int __real_foo(); in

在使用GCC编译器时，如果不想工程使用系统的库函数，例如在自己的工程中可以根据选项来控制是否使用系统中提供的malloc/free, new/delete函数，可以有两种方法： (1). 使用LD_PRELOAD环境变量：可以设置共享库的路径，并且该库将在任何其它库之前加载，即这个动态库中符号优先级是最高的。 (2). 使用GCC的--wrap选项：对symbol使用包装函数(wrapper ...

　　一直以来，我们所使用的NDS开发环境都是Windows下模拟Unix的编译环境。比如Msys，MinGW等等。这样的编译环境让时间整整倒转20年，回到了Unix时代。一切都由命令行来完成，复杂的编译工程不得不由Makefile来组织。没有带有语法提示的编辑工具，没有友好的集成环境，没有迅速简洁的除错机制。前些天我在PAlib的论坛上看到了VC2005集成编译的办法。但是整个实现还是基于Make
