The following example uses boost::iostreams with zlib support. It works and compiles fine under Linux (once the toolset is changed to gcc and the __declspecs removed). This is with BOOST_BUILD_PATH, ZLIB_SOURCE, NO_BZIP2 set, and starting with a boost distribution that has just bjam (and nothing else) compiled.

It does not work under Windows however. Starting with an unpacked boost distribution, it will compile compile zlib only to fail to find it almost immediately afterwards when linking the dll. I have tried a small example that uses a different boost library (e.g. date_time), and that compiles and links fine with a substantially identical jamfile.

What do I change so the example below compiles under Windows without having to do something like bjam --build-type=complete first? Many thanks.

Background: I am trying to make a demo distribution of a new library that would download boost and then compile the library and (only) the necessary parts of boost. This already works fine under Cygwin/Linux.

I'll be very grateful for any help.
