使用交叉编译过的xml静态库的问题？？

woodyk

我从网上下载的libxml2-2.6.30，解压后用
./configure --host=arm-linux-gnu --target=arm-linux CC=arm-linux-gcc AR=arm-linux-ar LD=arm-linux-ld RANLIB=arm-linux-ranlib --prefix=/usr/local/arm/3.4.1/arm-linux/
进行配置，然后
make
make install
将/usr/local/arm/3.4.1/arm-linux/lib/libxml2.a和/usr/local/arm/3.4.1/arm-linux/include/libxml2下的包含头文件的文件夹libxml一起拷贝到我的程序文件夹下，用
arm-linux-gcc -Wall -lm -L ./ -I ./ xmlfile.c -o testxml -lxml2
交叉编译，结果出现错误如下：

是什么原因呢？？该如何解决呢？？各位帮忙看看。
我用动态库链接时没有问题。

仔细查看源码后发现所有这些未定义函数都包含在zlib.h头文件中，在程序里这些函数都是根据如下宏定义去执行的：
#ifdef HAVE_ZLIB_H
#include <zlib.h>
#endif
............
#ifdef HAVE_ZLIB_H
.......执行函数........
#endif
但我找了好久也没找到在其他文件的什么位置有#define HAVE_ZLIB_H出现。即根本就没有包含头文件。
不知道是不是这个原因，仅当参考吧，各位再帮忙看看该怎么解决，谢了！！
