利用XML来作为Makefile的make工具源代码.-use XML as a Makefile to make the source code tool.

1. 编写一个C程序作为Linux内核的shell命令行解释程序。Shell程序应该使用与Bource shell相同的方式运行程序。 2. 增加功能以使用户可以使用"&"操作符作为命令的结束符。一个以"&"结尾的命令应该与shell并发执行。 3. 增加功能以使用户可以使用""作为文件名前缀来重定向stdin和stdout描述符。同样，允许用户使用管道操作符" "来同时执行两个进程，并把第一个进程的stdout重定向为第二个进程的stdin。-1. Preparation of a C program as a Linux kernel shell command line interpreter. Shell procedures should be used with Bource shell the same way as operational procedures. 2. Increased functionality so that customers can use, "" operator, as ordered by the end tags. A "" the end of the order should be concurrent with the implementation of the shell. 3. Increased functionality so that customers can use "lt;" "Gt;" As a filename prefix to redirect stdin and stdout descriptors. Similarly, allows users to use pipeline operator, "" two parallel processes, and a process to redirect stdout second process stdin.

程序是根据vidcat改的,只能抓PPM的图. makefile的内容如下,请注意打小写: cc=gcc #cflags=-i/firendly-arm/kernel/include -i/usr/local/arm/2.95.3/arm-linux/include -wall -dhave_libjpeg #-dvideo_dev="/dev/v4l/video0" -dversion="0.7.2" cflags=-wall -dvideo_dev="/dev/video0" -dversion="0.7.2" camsnap: camsnap.c 用法如下: camsnap -v -s 420x420 -o my.ppm 这儿请注意:s 的大小必需是8能整除的倍数. 这个程序我是在rh9下作的,需要交叉编译的朋友就把注释去掉,再给下面的注释就可以了.-Vidcat procedure is in accordance with the law, can only grasp PPM plans. Makefile reads as follows, please note that playing lowercase: cc = gcc# Cflags =- i/firendly-arm/kernel/include-i/usr/local/arm/2.95 .3/arm-linux/include-wall-dhave_libjpeg#-dvideo_dev =
