[Pkg-scicomp-devel] Bug#576896: libglpk-java does not build on kfreebsd

[glpk xypron]

Hello Kumar,

all aborts irrespective of architecture occur inside function
glpk_intopt() of the GLPK library.

The same routine will be called when executing
glpsol -m glpk-java-1.0.13/examples/java/marbles.mod

This will help to clarify if the observed problem is in libglpk-java.

GLPK makes use of long jumps. 
See the thread starting at
http://lists.gnu.org/archive/html/help-glpk/2008-08/msg00071.html

It would be helpful to run the following program

/**
 * Determination of the alignment of jmp_buf
 */
#include <stdio.h>
#include <setjmp.h>
#include <stddef.h>

/**
 * Determine the alignment of jmp_buf
 * @return alignment in bytes
 */
int jmp_buf_alignment()
{
#ifdef __GNUC__
   static int res = __alignof__ (jmp_buf);
#else
   struct t
   {  char a;
      jmp_buf b;
   };
   static int res = offsetof(struct t, b);
#endif
   return res;
}

int main()
{
  printf("jmp_buf is %d byte aligned\n", jmp_buf_alignment());
  return 0;
}

Best regards

Xypron
