本文介绍了一种自制的arm-linux-ldd脚本，该脚本能够在交叉编译环境中查看程序依赖的库文件。通过具体示例展示了如何使用此脚本进行依赖库的查找。

看了些许资料，在PC上可以用ldd查看程序的依赖库文件，但是交叉编译环境就没法查看了，查了查arm-linux-readelf的资料，找到了个实现arm-linux-ldd的方法。假设你的arm-linux-tools在目录/opt/arm-linux-tools，执行下面脚本：

1. gedit /opt/arm-linux-tools/bin/arm-linux-ldd &

输入以下脚本：

#! /bin/bash

function FindDep()
{
        for i in $*; do
                dependfile=`$pathname/arm-linux-readelf -a $i | gawk '/Shared library/{print $5}' | sed "s//[/|/]//g"`

                if [ ${#dependfile} -gt 0 ]; then
                        Solver ${dependfile}
                fi
        done
}

function Solver()
{
        for i in $*; do
                bFound=0

                for j in ${tmpArr[@]}; do
                        if [ $j = $i ]; then
                                bFound=1
                                break
                        fi
                done

                if [ $bFound -eq 0 ]; then
                        bRepeat=0
                        effectFile=
                        tmpArr[${#tmpArr[*]}]=$i
                        allFile=`find $gccPath | grep "$i$"`

                        if [ ${#allFile} -eq 0 ]; then
                                echo "$i -> "
            else
                for j in $allFile; do
                                    if [ $bRepeat -eq 0 ]; then
                                               bRepeat=1
                                            effectFile=$j
                                            echo "$i -> $j"
                                    else
                                            echo "${i//[A-Z,a-z,0-9,.,/+,/-,_]/ } -> $j"
                                    fi
                            done
                        fi

                        link=`ls -l $effectFile | gawk '//->/{print $10}'`

                        if [ ${#link} -ne 0 ]; then
                                Solver $link
                        fi

                        FindDep $effectFile
                fi
        done
}

pathname=$0

if [ ${pathname: 0: 1} = "." ]; then
        path=$PWD

        if [ ${path: ${#path}-1: 1} = "/"]; then
                pathname=$(dirname ${path}${pathname})
        else
                pathname=$(dirname ${path}/${pathname})
        fi
else
        pathname=$(dirname ${pathname})
fi

gccPath=`find $(dirname ${pathname})/arm-* | grep "/lib$"`
gccPath="$gccPath $extPath"

for i in $*; do
        if [ ${i: 0: 2} = "-L" -o ${i: 0: 2} = "-l" ]; then
                gccPath="$gccPath ${i: 2: ${#i}-2}"
        fi
done

for i in $*; do
        if [ ${i: 0: 2} != "-L" -a ${i: 0: 2} != "-l" ]; then
                tmpArr=()
                echo "dependence of $i is:"
                FindDep $i
                echo
        fi
done

2. chmod 755 /opt/arm-linux-tools/bin/arm-linux-ldd

搞定，现在可以使用arm-linux-ldd查看交叉编译文件的依赖库文件了。在我机子上(Ubuntu 10.04+arm linux 4.5.1 + Qt Embbeded 4.7.1)：
