If these problems occur during cross-compiler compilation, they may be caused by the differences between the pc compiler and the gcc version of the Cross-compiler. At this time, let's take a look at the PC version:

[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 particle PURPOSE.

This is version 4.8.1, while the gcc version of the cross compiler is version 4.5.4.

Make the following changes in the cross-compiler. config file:

[Fulinux @ the ubuntu buildroot-2012.08] $ vim. config
