 system information:
 Linux n1 2.6.8-24-smp #1 SMP Wed Oct 6 09:16:23 UTC 2004 x86_64 x86_64
 x86_64 GNU/Linux
 Bonmin verstion:Bonmin-0.1.1
 1. Downloaded student verstion AMPL-Unix and compiled its binary
 successfully.
 2. Successfully installed and compiled Bonmin based on available manual.
 3. Put the Bonmin binary in the search path $PATH, which makes it workable
 and invokable from any directory.
 4. Got ASL/solvers.
 5. cd solvers;
 6. Since my machine is 64, I changed the "CC = cc" in solvers/makefile.u
 into "CC = cc -m32", and student version AMPL-Unix is for 32 system as far
 as I know.
 7. make -f makefile.u
 8. cd funclink
 9. Similar to 6, I changed "CC = cc" in solvers/funclink/makefile.linux
 into "CC = cc -m32".
 10. make -f makefile.linux
 11. wrote the script file myexample.x as following:
     reset;
     function ginv(Reals);
     var x;
     minimize Z:x*x+x+1+ginv(x);
     subject to cons:x>=0.8;
     option solver bonmin;
     solve;
 12. ampl myexample.x
 13. I got the following errors after I implement 12
     bonmin:
     Cannot load
