GCC編譯uboot出現(.ARM.exidx+0x0): undefined reference to `__aeabi_unwind_cpp_pr0'錯誤的解決的方法

/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

一旦編譯uboot出現上述錯誤。請不要慌張！

解決的方法官網已經給出。主要解決的方法例如以下：

vim 打開./lib_arm/eabi_compat.c（詳細的位置依據自己的情況而定）並加入例如以下空函數就可以解決：

/* Dummy function to avoid linker complaints */

void __aeabi_unwind_cpp_pr0(void)

{

};
