  Have anyone in this list compile NEWMAT using DJGPP?


  NEWMAT is a package of matrices operation, written in C++,
intended to be compiled using BC++ 3.1. I got some bugs
compiling with DJGPP, which have been corrected, but now
I can't run the Cholesky factorization. Basically the bug
is that you have something like this:



<newmat.h>  :

  class MatrixType {
      private:
         .
         .    Private data elements
         .
      protected:
         .
         .    Some protected stuff 
         .

      public:
         .
         .    Some public methods
  
         friend Boolean Rectangular (MatrixType a, MatrixType b, MatrixType c)
           { return (Some_comparisions); }
         friend Boolean Compare (MatrixType, MatrixType);

  }

  Well, this header file is included by every module of the package
and then the loader say:


Multiple definition of symbol: Rectangular


  For each module he links... Well, I thought, "Why not take the code
of Rectangular out of the class, since it's a friend method?" It 
compiled... But the modules that uses this method cause a General
Protection Fault... 



    Can anyoune help me??
