linux有没有把一个二进制可执行文件制作成另一个并且把依赖库包含其中的工具啊？

Question

有些软件挂载到docker后无法执行。

Answer 1

有,比如可以用patchelf修改二进制程序的依赖库和链接器位置,然后把二进制程序和依赖的库(ldd找出来)一起打包即可.比如解压即用,跨Linux发行版PHP7打包文末提供了打包的方法:

pack.sh
#!/bin/bash
#运行 cd /png/pack && ./pack.sh
PHP=/png/php/7.0.0

#备份原有文件
tar cf /png/pack/backup/php7.tar "$PHP"
cp -R "$PHP" "${PHP}".backup

#找出二进制和共享库
PHP_BIN_LIB="$(find '$PHP' -type f -exec file -i '{}' \; | egrep 'x-executable; charset=binary|x-sharedlib; charset=binary' | awk -F ': ' '{print $1}')"
echo "$PHP_BIN_LIB" > bin_lib.txt
PHP_BIN="$(find '$PHP' -type f -exec file -i '{}' \; | grep 'x-executable; charset=binary' | awk -F ': ' '{print $1}')"
echo "$PHP_BIN" > bin.txt

#复制库链接器
cp /lib64/ld-linux-x86-64.so.2 /png/pack/libs

#复制依赖库
for i in `cat bin_lib.txt`; do
    deps="$(ldd '$i' | awk -F ' ' '{print $3}'|grep '.so')"
    for j in "$deps"; do
        cp -n "$j" /png/pack/libs
    done
done

#设置二进制文件的rpath和interpreter
for i in `cat bin.txt`; do
    /png/pack/patchelf --set-rpath /png/pack/libs --force-rpath "$i"
    /png/pack/patchelf --set-interpreter /png/pack/libs/ld-linux-x86-64.so.2 "$i"
done

#打包库和修改后的程序
tar cJf /png/pack/php7.tar.xz /png/pack/libs "$PHP"
