linux自带的gcc编译器，用file led_1后：
led_1: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not stripped
arm-linux-gcc编译器，用file led后
led: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, not stripped
请问：如果自己要做一个新的项目，是不是也要自己写（或者移植）一个编译器？若要移植，又该怎么做呢？
