compiled executable with VC++ express doesn't start

[mrbook at gmail.com]

Hello,
I've been fighting with this one all day :)  I've tried compiling a
wxwidgets application with Visual C++ Express from the command line
with scons and it compiles fine. But when I run the produced
executable, a window never appears. Compiling the same source from the
Visual C++ IDE interface works fine and the executable runs correctly.
Does anyone know what I may be doing wrong?
This is my linking command.
