centos安装arm交叉工具链后常见的问题解决

[root@localhost osdrv]# arm-hisiv400-linux-gcc -v
bash: /opt/hisi-linux/x86-arm/arm-hisiv400-linux/target/bin/arm-hisiv400-linux-gcc: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory
这是缺少32位的库，按照如下安装：

[root@localhost osdrv]# yum install glibc.i686

安装完毕后再次运行：

[root@localhost osdrv]# arm-hisiv400-linux-gcc -v
arm-hisiv400-linux-gcc: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

这是缺少libstdc++.so.6:

按照如下查找安装：

[root@localhost osdrv]# yum whatprovides libstdc++.so.6
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
 * base: mirrors.btte.net

libstdc++-4.8.3-9.el7.i686 : GNU Standard C++ Library
Repo        : base
Matched from:
Provides    : libstdc++.so.6

[root@localhost osdrv]# yum install libstdc++-4.8.3-9.el7.i686

好了，大功告成：

[root@localhost osdrv]# arm-hisiv400-linux-gcc -v
Using built-in specs.
