Mac OSX linker boost::system category referenced from static..

[noah.whiteis@…]

When I compile Boost.asio or boost.filesystem code (GCC4.3) in mac osx I get

Build boosttesttwo of project boosttesttwo with configuration Debug

Boost.System and Boost.FileSystem are not header-only libraries. You need to create the libraries and link to them.

By the way, it appears that you created four identical tickets - was that on purpose?

I do have the libraries for each library including filesystem and system in dylib

[Marshall Clow]

But in the build commands that you posted, I see no evidence that you are linking to them.

-l libSystem (say)
