Hi,

looks like you're not linking against the Symphony libraries (thus the missing
sym_close_environment) (and I guess Matlab libs are next). It's not enough
that you specify the library paths, you need to specify the actual libraries
too (so convert those -l options and remember to specify the complete name as
-l does prefix and append things). You may pass the linker the /VERBOSE option
to see what it actually tries to do; Sometimes it's quite useful.

(This works mostly "automatically" with Boost as Boost.Config uses certains
MSVC specific #pragmas to tell the linker (thru compiler) which libraries to
link against so all you need to worry about is the path.)
