关于binutils-2.10.1二进制工具问题

spirit_cg

在执行$../binutils-2.10.1/configure --target=$TARGET --prefix=$PREFIX后：
checking for flex... no
checking for lex... no
../../binutils-2.10.1/binutils/configure: line 1945: flex: command not found
checking for flex... lex
checking for yywrap in -ll... no
checking lex output file root... ../../binutils-2.10.1/binutils/configure: line 2033: lex: command not found
configure: error: cannot find output from lex; giving up
Configure in /home/spirit/embedded/build-tools/build-binutils/binutils failed, exiting.
得到以上出错信息，查看configure文件,里面出现lex以及flex，请问这个两个程序有什么作用？谢谢
