This is not a valid -l syntax, as gcc's fine manual will tell. In addition,
you really supposed to install boost, and then link to the library in the
install tree.

Have you previously linked to static libraries from a CDT project? If not,
I suggest you start by doing that -- like by creating separate "Static library"
CDT project, building it, and putting the library somehwere and trying to link to it
from an Executable project. We can't help with this part.

If you've done that successfully, can you describe in what what the library
produced by building Boost is wrong, so that CDT can't link to it? So far,
your question seems like generic CDT user question, and we don't support CDT.
