can't compile fluka

         Hello all.
         I installed the fluka 2011 32 bits without problema in my machine.
I use the gcc/g77 version 4.4 for this.
        I try to compile the new version of Corsika (6990 version), but I
can't even extract the Corsika source code. I using the same compiling
that I use to compile fluka 32 bits.
        Anyone can you help me about this?
       Follow the Corsika error message:
