Ubuntu下libxml2的交叉编译

Ubuntu下libxml2的交叉编译，有需要的朋友可以参考下。
环境为Ubuntu 14.04 LTS 64位 英文版本。
使用的交叉编译工具是arm-linux-gcc-4.3.2.tgz。
一、准备libxml2库
libxml2是一个跨平台的xml文件操作库。
项目地址：http://www.xmlsoft.org/
我使用的是最新版本libxml2-2.9.2.tar.gz
二、安装
我在在官网提供的网址https://git.gnome.org/browse/libxml2/上下载了几个版本的.tar.gz在Ubuntu下解压以后都没有看到configure文件，然后在ftp://xmlsoft.org/libxml2/下载的版本里却有configure文件……折腾一早上，简直坑爹，希望朋友们少走弯路……
在解压文件夹下
rootroot@rootroot-virtual-machine:~/wyb$ cd libxml2-2.9.2/
rootroot@rootroot-virtual-machine:~/wyb/libxml2-2.9.2$ ./configure --prefix=/home/rootroot/wyb/libxml2-2.9.2/install CC=arm-linux-gcc LD=arm-linux-ld --enable-shared --enable-static --host=arm-linux --with-python=/home/rootroot/wyb/libxml2-2.9.2/python
rootroot@rootroot-virtual-machine:~/wyb/libxml2-2.9.2$ make
rootroot@rootroot-virtual-machine:~/wyb/libxml2-2.9.2$ make install
注意修改自己的交叉编译工具。如果不指定python路径（--with-python=/home/rootroot/wyb/libxml2-2.9.2/python），make之后会提示：
rootroot@rootroot-virtual-machine:~/wyb/libxml2-2.9.2$ make
make[4]: Entering directory `/home/rootroot/wyb/libxml2-2.9.2/python'

Linux中交叉编译libxml2
三、测试
随便找一个测试程序：
// test.c
#include
#include
#include
int main(int argc, char **argv)
{
xmlDocPtr doc = NULL;
xmlNodePtr root_node = NULL, node = NULL, node1 = NULL;
doc = xmlNewDoc(BAD_CAST "1.0");
root_node = xmlNewNode(NULL, BAD_CAST "root");
xmlDocSetRootElement(doc, root_node);
xmlNewChild(root_node, NULL, BAD_CAST "node1",BAD_CAST "content of node1");
node=xmlNewChild(root_node, NULL, BAD_CAST "node3",BAD_CAST"node has attributes");
xmlNewProp(node, BAD_CAST "attribute", BAD_CAST "yes");
node = xmlNewNode(NULL, BAD_CAST "node4");
node1 = xmlNewText(BAD_CAST"other way to create content");
xmlAddChild(node, node1);
xmlAddChild(root_node, node);
xmlSaveFormatFileEnc(argc > 1 ? argv[1] : "-", doc, "UTF-8", 1);
xmlFreeDoc(doc);
xmlCleanupParser();
xmlMemoryDump();
return(0);
}
编译：
