Re: [Boost-users] Problem linking with boost 1, 51 64-bits from boostpro, VC10

To make a long story short: I compiled boost from source, and it worked, so
I suspect either a problem with the package or, more likely, some file got
corrupted while I downloaded or installed.

I don't explicitly link with any library. I just indicate in VS where to
look for libraries. It worked for years when compiling with 32-bit
libraries, and it worked after I used the boost 64-bit library that I
compiled myself, but didn't using the pre-built package that I downloaded.
Only difference is that the pre-built one I downladed is 1.53, everything
else was 1.51 and (sometimes much) earlier.

Thanks for your help.
