64ビットUbuntuで32ビットpythonを実行できません：共有ライブラリの読み込み中にエラーが発生しました：libutil.so.1

32ビットバージョンのpython 64ビットUbuntu12.04で実行しようとしています。この特定のバイナリを実行する代わりの方法がありますが、回避策よりもエラーの原因を理解することに関心があります。それのための。

これは私が得ている完全なエラーです：

/build/toolchain/lin32/python-2.7.1/bin/python: error while loading shared libraries: libutil.so.1: cannot open shared object file: No such file or directory

同じシステムを使用して自分のマシンでlddを実行している友人がいて、欠落していた正確なライブラリパスを確認しました。

$ ldd /build/toolchain/lin32/python-2.7.1/bin/python
    linux-gate.so.1 =>  (0xf77c5000)
    libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0xf778e000)
    libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0xf7789000)
    libutil.so.1 => /lib/i386-linux-gnu/libutil.so.1 (0xf7784000)
    libm.so.6 => /lib/i386-linux-gnu/libm.so.6 (0xf7758000)
    libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xf75ae000)
    /lib/ld-linux.so.2 (0xf77c6000)

私のシステムでは、libutil.so.1行に対して

libutil.so.1 => not found

興味深いのは、友人が私のマシンに持っているのと同じ共有ライブラリを持っていることです。

$ ls /lib/i386-linux-gnu/libutil.so.1 
/lib/i386-linux-gnu/libutil.so.1

それで、私がライブラリを持っているのなら、なぜpythonそれを見つけることができないのですか？

最新のpythonは正常に動作し、ツールチェーンにある64ビットバージョンのpython 2.7.1でも正常に動作することは注目に値するかもしれません。

apt-fileの使用：

$  apt-file search  libutil.so.1
libc6: /lib/x86_64-linux-gnu/libutil.so.1
libc6-armel-cross: /usr/arm-linux-gnueabi/lib/libutil.so.1
libc6-armhf-cross: /usr/arm-linux-gnueabihf/lib/libutil.so.1
libc6-i386: /lib32/libutil.so.1

したがって、libc6-i386をインストールすると問題が解決するはずです。

$ Sudo apt-get install libc6-i386

それでも機能しない場合は、シンボリックリンクの作成を試みることができます（以前に古いファイルをバックアップしてください！）：

$ Sudo ln -s /lib32/libutil.so.1 /lib/i386-linux-gnu/libutil.so.1
