How to build a static boost library?

More specifically static boost::iostreams with zlib (aka libz) support.

The problem is, that when I try to link static library it throws unresolved symbols. At the same time when I try to link dynamic library everything works...

I've been searching for answer for several days and can't find it yet.

The command I use to build shared library: b2 -a -q -j8 address-model=32 toolset=gcc --with-iostreams link=shared runtime-link=shared -sZLIB_INCLUDE="path" -sZLIB_LIBPATH="path" -sBZIP2_INCLUDE="path" -sBZIP2_LIBPATH="path"

The command I use to build static library: b2 -a -q -j8 address-model=32 toolset=gcc --with-iostreams link=static runtime-link=static -sZLIB_INCLUDE="path" -sZLIB_LIBPATH="path" -sBZIP2_INCLUDE="path" -sBZIP2_LIBPATH="path"

Example of the program:

#include <iostream>#include <boost/iostreams/filter/gzip.hpp>int main(int argc, char* argv[]) {  int a = boost::iostreams::zlib::default_compression;  std::cout << a << std::endl;  return 0;}

The exception I get:

UPDATE:Also in case the problem may be related to zlib or bz2: I got bz2 lib here: http://gnuwin32.sourceforge.net/packages/bzip2.htm and zlib here: http://gnuwin32.sourceforge.net/packages/zlib.htmAnd I tried to build zlib myself with their win32 makefile. I got libz.a and tried to build with it as well, nothing's changed.
