linux下xml安装和使用

xml安装和使用

需要文件：mxml-2.7.tar usemxml.c test.xml

步骤：

1.mxml-2.7.tar拷到共享文件夹
2.linux进入共享文件夹
3.#sudo su
4.#cp mxml-2.7.tar.gz /home/
5.#tar -xvf mxml-2.7.tar.gz
6.#cd mxml-2.7
7.#./configure
8.make install
9.#cp /usr/local/lib/libmxml.* /lib
10.进入共享文件夹运行
11.#gcc usemxml.c -lmxml -lpthread
12../a.out
