None of the config files was changed initially. I also tried running
boost_1_31_0/libs/config/configure and using the user.hpp that it
generated. That file has BOOST_HAS_PTHREADS defined, but I get the same
result.
In re-reading my post, I realize that it may sound like I'm getting
this error when trying to build Boost. Not the case, Boost seems to
build ok and I get the 2 thread dylibs. It's when trying to use the
thread library in my code that I get the above. Am I wrong in assuming
that, since I ended up with the 2 thread dylibs, the problem is not in
the Boost build process?
Thanks
