编译gcc error-*** LIBRARY_PATH shouldn‘t contain the current directory when *** building gcc.

LD_LIBRARY_PATH以冒号结尾，GCC不赞成该冒号。 还应确保C_INCLUDE_PATH不以冒号结尾，以避免出现相关问题。 方法如下：

方法一：

重新export LIBRARY_PATH和C_INCLUDE_PATH 尾部不含冒号

方法二：

export LIBRARY_PATH=$(echo $LIBRARY_PATH | sed 's/:$//; s/^://;')
export C_INCLUDE_PATH=$(echo $C_INCLUDE_PATH | sed 's/:$//; s/^://;')
方法2仿佛有效

error: #error GATHER_STATISTICS must be defined

export CPP_INCLUDE_PATH=
