Since the Ubuntu system uses the GCC compiler, the compilation result is an X86 file, which can only be run on X86 and cannot be run directly on ARM. Therefore, a "Ubutun cross-compilation tool chain" must be installed before it can run on ARM.
arm-none-linux-gnueabi-gcc is an ARM cross-compilation tool based on GCC launched by Codesourcery (currently acquired by Mentor) . lsb-core lib32stdc++6 is a related library that needs to be installed.
