/opt/arm-2010.09/bin/../lib/gcc/arm-none-linux-gnueabi/4.5.1/armv4t/libgcc.a(_bswapsi2.o):(.ARM.exidx+0x0): undefined reference to `__aeabi_unwind_cpp_pr0‘
make: *** [u-boot] Error 1

一旦编译uboot出现上述错误，请不要慌张！解决办法官网已经给出，主要解决办法如下：

vim 打开./lib_arm/eabi_compat.c（具体的位置根据自己的情况而定）并添加如下空函数即可解决：

/* Dummy function to avoid linker complaints */

void __aeabi_unwind_cpp_pr0(void)

{

};

以下为官网原内容：
