Description: In order to thoroughly understand what makes Linux tick and why it works so well on a wide variety of systems, you need to delve deep into the heart of the kernel. The kernel handles all interactions between the CPU and the external world, and determines which programs will share processor time, in what order. It manages limited memory so well that hundreds of processes can share the system efficiently, and expertly organizes data transfers so that the CPU isn t kept waiting any longer than necessary for the relatively slow disks.-In order to thoroughly understand what mak es Linux tick and why it works so well on a wide var iety of systems, you need to delve deep into the heart of the kerne l.

Description: 总的来说，在uClinux上的开发和标准Linux还是很类似的。通常可以按照下面的步骤去设计和调试： 建立基于以太网的开发环境； 如果所设计的程序和硬件的关联不大，那么一定要在标准Linux上先编译和调试通过。灵活地使用gcc和gdb将大大节省时间； 将x86上的GCC编译好的应用程序用交叉编译工具来编译；如果编译时发现错误，那么很可能存在以下问题： 交叉编译器或库文件的路径不正确；最彻底的解决办法是重新装一次编译器； 遇到库不支持的函数；此时需要自己把函数的实现做成另外一个库供应用程序使用。如果是uClinux本身不支持的调用，那么就需要改写代码了。-Overall, the uClinux on the development and standard Linux is still very similar. Usually can use the following steps to design and debug : Ethernet-based development environment; If the design of the procedure and not linked to the hardware, then it must be the first standard Linux compiler and debugging through. Flexibility in the use of gdb and gcc will greatly save time; X86 will be on the GCC-compiled application with cross-compiler tool to compile; If you compile time error is found, it was very likely that the following issues : cross-compilers or libraries are not the correct path; The most radical solution is a re-installed time compiler; encountered does not support functions; At this time the need to keep the realization of function caused another one for the supply of the proce

Description: 这是linux下关于进程操作的两个例子,分别是"父子进程都写入文件"和"管道-两个子进程写父进程读".这两个程序对初学都理解linux下的多进程操作很有帮助.在linux GCC下编译通过.-This is under linux operating on two examples of the process, namely the " father and son have been entered into the process of document" and " pipeline- the father of two sub-process in the process of writing time." These two procedures are learning to understand more the process of linux operating under very helpful. in the next linux GCC compiler through.
