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&＃20284;的修改：

[fulinux@ubuntu buildroot-2012.08]$ vim .config

#

# BR2_GCC_VERSION_4_3_X is not set

# BR2_GCC_VERSION_4_4_X is not set

BR2_GCC_VERSION_4_7_X=y

# BR2_GCC_VERSION_SNAP is not set

BR2_GCC_SUPPORTS_FINEGRAINEDMTUNE=y

# BR2_INSTALL_FORTRAN is not set

BR2_GCC_SHARED_LIBGCC=y
