Using Bin With High Glibc In Low Glibc Env

发表于 2026-06-28 分类于 Linux

问题

众所周知，zip 在 Windows 下打包时使用了本地编码，但 Linux 下解压却使用 UTF-8 编码，导致中文乱码。

我有 unzipi，可以解决这个问题。但当我要在一台低版本 glibc 环境下运行时，我这用高版本构建的 unzipi 无法运行。

[demo@vmdeb ~]# unzipi
unzipi: /lib64/libc.so.6: version `GLIBC_2.33' not found (required by unzipi)
unzipi: /lib64/libc.so.6: version `GLIBC_2.34' not found (required by unzipi)

解决记录

上传高版本 libc.so.6，指定 glibc 路径

[demo@vmdeb ~]# LD_LIBRARY_PATH=/lib64/glibc233/ unzipi
unzipi: /lib64/ld-linux-x86-64.so.2: version `GLIBC_2.35' not found (required by /lib64/glibc233/libc.so.6)

仍然受限于 ld-linux-x86-64.so.2

上传高版本 ld-linux-x86-64.so.2，ld-linux 指定路径

将 unzipi 重命名为 unzipi.glibc233

编写脚本命名为 unzipi

#!/bin/bash

GLIBC_DIR=/lib64/glibc233
$GLIBC_DIR/ld-linux-x86-64.so.2 \
    --library-path $GLIBC_DIR \
    /bin/unzipi.glibc233 "$@"

再执行

[demo@vmdeb glibc233]# unzipi
/bin/unzipi.glibc233: error while loading shared libraries: libbz2.so.1.0: cannot open shared object file: No such file or directory

说明缺少 libbz2.so.1.0

软链接 libbz2.so.1.0

[demo@vmdeb glibc233]$ ls -alh
total 2.2M
drwxr-xr-x.  2 root root   72 Jun 27 22:46 .
dr-xr-xr-x. 48 root root  28K Jun 27 22:38 ..
-rwxr-xr-x.  1 root root 221K Jun 27 22:36 ld-linux-x86-64.so.2
lrwxrwxrwx.  1 root root   16 Jun 27 22:46 libbz2.so.1.0 -> ../libbz2.so.1.0
-rwxr-xr-x.  1 root root 2.0M Jun 27 22:36 libc.so.6

运行成功

[demo@vmdeb glibc233]# unzipi
UnZip 6.00 of 20 April 2009, by Debian. Original by Info-ZIP.

Usage: unzip [-Z] [-opts[modifiers]] file[.zip] [list] [-x xlist] [-d exdir]
  Default action is to extract files in list, except those in xlist, to exdir;
  file[.zip] may be a wildcard.  -Z => ZipInfo mode ("unzip -Z" for usage).

  -p  extract files to pipe, no messages     -l  list files (short format)
  -f  freshen existing files, create none    -t  test compressed archive data
  -u  update files, create if necessary      -z  display archive comment only
  -v  list verbosely/show version info       -T  timestamp archive to latest
  -x  exclude files that follow (in xlist)   -d  extract files into exdir
modifiers:
  -n  never overwrite existing files         -q  quiet mode (-qq => quieter)
  -o  overwrite files WITHOUT prompting      -a  auto-convert any text files
  -j  junk paths (do not make directories)   -aa treat ALL files as text
  -U  use escapes for all non-ASCII Unicode  -UU ignore any Unicode fields
  -C  match filenames case-insensitively     -L  make (some) names lowercase
  -X  restore UID/GID info                   -V  retain VMS version numbers
  -K  keep setuid/setgid/tacky permissions   -M  pipe through "more" pager

  -O CHARSET  specify a character encoding for DOS, Windows and OS/2 archives
  -I CHARSET  specify a character encoding for UNIX and other archives

See "unzip -hh" or unzip.txt for more help.  Examples:
  unzip data1 -x joe   => extract all files except joe from zipfile data1.zip
  unzip -p foo | more  => send contents of foo.zip via pipe into program more
  unzip -fo foo ReadMe => quietly replace existing ReadMe if archive file newer
