FLEX Package not installed

    To confirm that you do not have the FLEX Package installed, type:
    flex --version
 
    If it says no version for FLEX package found, then you need to install the FLEX package.  

    Try:
    yum install flex
    or:
    apt-get install flex  

   
    You can also find RPMs here

C++ Compiler not installed

    To confirm that you do not have a C++ Compiler (g++) installed, type:
    g++ --version
 
    If it says no version for g++ package found, then you need to install the gcc-c++ package.  

    Try:
    yum install gcc-c++
    or:
    apt-get install gcc-c++ or: apt-get install g++
    
    You can also find RPMs here

The install script fails at the utility installation with the following error:

Compiling WANPIPE WanCfg Utility ...
Failed!
                !!! WANPIPE WanCfg Compilation Failed !!!
        Possible solution:
                 FLEX Package not installed
                 Non-standard C/C++ library (eg: ulibc)

This is a catch all error, it may be either FLEX or C++ compiler (g++) is not installed, please confirm that both are.
