(1) 动态编译
arm-linux-gnueabi-gcc -o hello hello.c
arm-linux-gnu-eabi-strip hello
file hello
hello: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.16, stripped
arm-linux-gnueabi-gcc -o hello hello.c arm-linux-gnu-eabi-strip hello file hello hello: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.16, stripped (2) 静态编译
arm-linux-gnueabi-gcc -o hello hello.c -static
arm-linux-gnu-eabi-strip hello
hello: ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically linked, for GNU/Linux 2.6.16, stripped
