This period of time sharpening pain determined to learn the development of embedded systems, and then installed a Linux virtual machine, download u-boot ready to patch recompile encountered a tricky problem.
That is ARM-LINUX-GCC: command not found.
This problem troubled me a day, ask a lot of great God finally to solve it, the following I write a solution to share the process for you.
1. See if ARM-LINUX-GCC compiled software is installed
Download arm-linux-gcc-3.4.5-glibc-2.3.6.tar.bz2
Input command tar xjf arm-linux-gcc-3.4.5-glibc-2.3.6.tar.bz2 extract File
2. Setting Environment variables
3. Determine if the environment variable is set up or there is a problem that ARM-LINUX-GCC cannot find
Enter the following three commands
sudo apt-get install Ia32-lib
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0
sudo apt-get install lib32stdc++6
The problem has been solved
About ARM-LINUX-GCC already configured environment variables can also show problems that could not be found
