Sorry for the mail bombing... I am trying to run the exe and no matter what I try typing in, I get a usage error. I have the path set to boost\boost_1_38\bin so I can run bcp anywhere.

I go to boost\boost_1_38 and type: bcp boost\regex.hpp \temp (temp is the output dir for me), and I get the usage error? What am I doing wrong?

Without the full error message it's hard to say, but I suspect that \temp isn't being seen as a valid path, try ./temp if that's what you want, or else a full path. HTH, John.
