Ubuntu下进行交叉编译时报错：arm-arago-linux-gnueabi-gcc: No such file or directory

一、问题描述。

在64位Ubuntu下进行交叉编译时报错“arm-arago-linux-gnueabi-gcc: No such file or directory”。

arm-arago-linux-gnueabi-gcc: No such file or directory
arm-arago-linux-gnueabi-g++: No such file or directory

二、问题分析。

此gcc可执行文件是32位版本，而在64位系统上运行需要安装32位兼容包才可能正常运行。

用file命令查看这个文件如下：

ms@ubuntu:~$ file ./bin/arm-arago-linux-gnueabi-gcc
bin/arm-arago-linux-gnueabi-gcc: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.2.5, with debug_info, not stripped
ms@ubuntu:~$ file ./bin/arm-arago-linux-gnueabi-g++
bin/arm-arago-linux-gnueabi-g++: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.2.5, with debug_info, not stripped
ms@ubuntu:~$

三、解决办法。

1、安装32位的依赖库ia32-libs，安装此库文件后，问题解决。

sudo apt-get install ia32-libs -y

2、在ubuntu13.04版本之后，ia32-libs库文件已经被弃用，替代安装包为lib32z1、lib32ncurses5或lib32ncurses6，安装其一便可解决问题。

3、安装依赖库返回信息如下所示。

sudo apt-get install lib32z1 -y
