Everything's works if - compiling with GCC, or - none of the source files includes boost/filesystem.hpp.

The link settings are

<threading>multi <link>static <runtime-link>static

Here are the symptoms:

boost_filesystem-vc80-mt-sd-1_34.lib

is built, but linking fails because

... cannot open file 'libboost_filesystem-vc80-mt-sgd-1_34.lib'

. Adding

<runtime-debugging>off

to the link settings changes error message to

... cannot open file 'libboost_filesystem-vc80-mt-s-1_34.lib'

I'm using Boost.Build V2. There is an example project that shows the problem attached to this post (note the path to Boost in 'project-root.jam' needs manual adjustment).

I believe this is a bug in bbv2: I complained about this a while back and just got a message that it hadn't been implemented yet. The problem is that bbv2 is mangling the library filenames in a manner differently to bbv1, and documented in our getting started guide. You may want to turn autolinking off by defining BOOST_ALL_NO_LIB when compiling until someone fixes this in bbv2. John.
