Re: [Boost-build] linking with msvc cannot find .lib

Hi me again,

So it seems that when I build my libraries the .lib
import libraries are not created somehow, but the
corresponding .dll files are. When I link the
executable it looks for the import library and cannot
find it obviously. Therefor I have some new (obvious)
questions:

* Why is speedo_handlers.lib not build?
* Is it possible to link to the speedo_hanedlers.dll
directly instead of speedo_handlers.lib? Or is this
silly?

Thanks for your help again, very much appreciated.

Cheers,
Andrej
