Today, try to run gcc tool chain under Ubuntu 64bit fails when arm-linux-gcc does exist. Finally find the tool is a 32-bit binary program.
However, ia32-libs is no longer supported by Ubuntu 15.
Doesn‘t matter. We can use package lib32z1 and lib32ncurses5.
I believe you may find the tip when run the command : sudo apt-get install ia32-libs
