哪位高手可以帮我解答下疑问，感激不尽，最好能讲清楚原理，比如ld是怎么查找luuid的，本人比较喜欢寻根究底

Qtopia在arm上的移植错误：cannot find -luuid 收藏
解决办法：
交叉编译e2fsprogs-1.38.tar.gz
$tar zxvf e2fsprogs-1.38.tar.gz
$cd e2fsprogs-1.38
$export CC=arm-linux-gcc //指定编译器
$./configure --host=arm-linux –enable-elf-shlibs
$make
$cd lib //进入lib目录
$cp libuuid.* /xxxxx/qtopia-free-2.1.1/lib //libuuid开头的库文件都拷贝到qtopia的lib目录
$cp –r uuid /xxxxx/qtopia-free-2.1.1/include //uuid文件夹拷贝到qtopia的include 文件夹下
