Hi all,

Forgive a potentially silly question from a complete novice.  I'm trying to
run the 'milp.c' example to learn how Symphony works.  I'm using Visual C++
express 2008 with the 'Symphony-5.1.1-win32-msvc-v8' binaries package.
'milp.c' compiles fine but has trouble linking.  I get the following errors:

main.obj : error LNK2019: unresolved external symbol
_sym_close_environment referenced in function _main
main.obj : error LNK2019: unresolved external symbol _sym_get_obj_val
referenced in function _main
main.obj : error LNK2019: unresolved external symbol
_sym_get_col_solution referenced in function _main
main.obj : error LNK2019: unresolved external symbol _sym_solve
referenced in function _main
main.obj : error LNK2019: unresolved external symbol
_sym_explicit_load_problem referenced in function _main
main.obj : error LNK2019: unresolved external symbol _sym_get_infinity
referenced in function _main
main.obj : error LNK2019: unresolved external symbol
_sym_open_environment referenced in function _main
C:\Documents and Settings\yang.sui\My Documents\Visual Studio
2008\Projects\symphony\Debug\symphony.exe : fatal error LNK1120: 7
unresolved externals


I believe all my include directories are correctly set, as well as library
dependencies.  I've tried using Visual C++ 2005 and but end up with the
exact same problems.  I also built the symphony code from source using
Cygwin and tried the 'milp.c' example in Eclipse but I have the same
problems there.

What am I doing wrong?

Thanks in advance for your time.
