It is boost library issue. Looks like you are not using the capture method of boost properly . Look at some examples of boost and fix your issue.
if you mean here:
than no, you did not make the changes @aha_1980 told you to do
still mising \ at the end of the line
also you are adding the widgets module twice. I'm not sure in what that will result, but you should remove one
Did you try to run your application through debugger to see why it crashes?
Any error messages?

heh – I must be receiving your comments telepathically – I just "discovered" that a few minutes before seeing your comment.
For b, check whether the library has other dependencies. You might be missing one.
library naming is something OS related (for instance the filename for a dynamic library called foo on Windows with Visual Studio will be foo.dll, on Linux libfoo.so, on OS X libfoo.dylib).
For this reason when you pass the library name to the linker you have to omit the prefix (ususally lib) and the extension.
NOTE in case of MinGW you'll have the naming conventions used in Linux/Unix (lib<library_name>.<extension>)
