Re: Setting library search path for linker

I think I had read the page you referenced, but I clearly hadn't
undersood it. I think I do now.

On Windows though, I don't need to explicitly add the boost library to
the link step, just the directory (the OBJ files have the name of the
library written in them in using the "auto link" facility. Can I make
use of this, or do I have to write

lib boost_filesystem : <name>libboost_filesystem-gcc-mt-d-1_31.lib
<search>c:\boost\lib ;

lib lib1 : $(SOURCES) boost_filesystem ;

Thanks for the quick response.
