64位ubuntu运行32位程序

摘自http://askubuntu.com/questions/454253/how-to-run-32-bit-app-in-ubuntu-64-bit

"No such file or directory" may appaear when you have your binary, but it lacks some libraries.

If you install build-essential package, you will have ldd command available.

This command ldd ./app | grep not will show you what libraries are missing.

Just install these libraries in i386 arch with apt. Like this: apt-get install libmissing:i386

Beware, some buggy packages will try to delete 64bit version firs.

To run a 32-bit executable file on a 64-bit multi-architecture Ubuntu system, you have to add thei386 architecture and install the three library packages libc6:i386,libncurses5:i386, and libstdc++6:i386

sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
