Hi, In configuring binutils-2.9.1, I get the following messages: checking lex output file root ./configure:line 1701: lex command not found configure error cannot find output from lex: giving up configure in /opt/gcc-4.3.2/binutils-2.9.1 failed exist. My question is: Is this a nornal error? Can you please help. I am configuring and installing prerequisites for GCC Thx
