[Clp] Input formats for clp binary

[André Scholz]

Hello,

i compiled cbc and clp on debian wheezy and using the file test.lp containing

   max: 0 ;
    x1 - x2 < 0 ;
   -x1 + x2 < 0 ;

i get the results:

   me at machine> ./clp test.lp
   Coin LP version 1.14.4, build Nov 14 2011
   command line - ./clp test.lp 
   terminate called after throwing an instance of 'char const*'

and

   me at machine> ./cbc test.lp 
   Welcome to the CBC MILP Solver 
   Version: 2.7.5 
   Build Date: Nov 14 2011 

   command line - ./cbc test.lp (default strategy 1)
   terminate called after throwing an instance of 'char const*'

What am i doing wrong?

Kind regards,
André
