make: *** [/opt/buildroot-2012.08/output/toolchain/gcc-4.5.4-initial/.compiled] 错误 2
如果编译交叉编译器是出现这些问题可能就是pc上的编译器和交叉编译器的gcc版本不同引起的,这时候看一下PC的版本:
[fulinux@ubuntu buildroot-2012.08]$ gcc --version
gcc (Ubuntu/Linaro 4.8.1-10ubuntu8) 4.8.1
Copyright (C) 2013 Free Software Foundation, Inc.
This is free software; see the source for copying conditions. There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
这是4.8.1的版本,而交叉编译器的gcc版本是4.5.4版本。
在交叉编译器的.config文件中作如下类似的修改:
[fulinux@ubuntu buildroot-2012.08]$ vim .config
