求助，linux下编译gcc过程中出现error

coldfire12

使用的GMP、MPFR、MPC这三个库分别为gmp-5.0.2,mpc-0.9,mpfr-3.1.0。

自己写了一个sh文件，内容如下：

export LD_RUN_PATH=/usr/local/lib:/usr/local/mpfr/lib:/usr/local/gmp/lib:/usr/local/mpc/lib
export LD_LIBRARY_PATH=/usr/local/lib:/usr/local/mpfr/lib:/usr/local/gmp/lib:/usr/local/mpc/lib
../configure --prefix=/usr/bin/gcc-4.6 --enable-languages=c,c++ --with-gmp=/usr/local/gmp --with-mpfr=/usr/local/mpfr --with-mpc=/usr/local/mpc --enable-libgomp



输出的错误信息如下：

有没有高手帮一下，难道我下载的gcc源代码中有错误？

dspecialtwo

undefined reference ==> no reference ?

1.include header file
2.include library

coldfire12

回复 2# dspecialtwo


    我是照着网上的教程来的，不知道该include哪个库啊。

EricFisher

这个比较奇怪，莫非你机器上没有安装flex和binson？

coldfire12

回复 4# EricFisher


    确实没装，刚刚找公司的人问了问，才装上，现在正在重新来过。

呃，我是菜鸟，网上的教程居然没有说要装这个 - -！

xiaoquan9653

我也是同样的问题啊，但是flex和bison都装了呀，请问是怎么回事呀？？？
