No such file or directory及解决方法

2024-04-12 12:47:18

背景：
1.新安装的ubuntu16.04LTS
2.编译uboot时提示：

arm-none-linux-gnueabi-gcc -v
bash: /home/zz/work/vz/src/trunk/build/../prebuilds/toolchain/arm-none-linux-gnueabi-4.3.3/bin/arm-none-linux-gnueabi-gcc: No such file or directory

到提示指向的目录查看文件确实存在，环境变量里面的PATH的值也有这个路径，但它还是提示没有这个文件。

到这里需要考虑是否是32bit和64bit的运行环境的问题。
ubuntu16.04是几天前重新安装的，安装之前是可以正常编译uboot的，但是现在使用新的ubuntu16.04会提示错误。于是搜了一下，按照提示方法操作之后就可以了，果然是32bit和64bit差异的问题。主要方法是64bit的ubuntu16.04运行32bit的可执行程序需要使用32bit的库来支持它。不考虑旧库换新库的事，此时此刻进需要安装两个32bit的库就行了。

1. lib32ncurses5
2. lib32z1

接下来再执行make就正常了。
