I am using the Boost library in Linux, GCC. After installing and building the Boost, I found that programs using Regex and Thread use shared Boost libraries. For my purposes, I need static linking. How can I change linking type? Should I rebuild the Boost, or maybe I can set linking type by defining some constant in my own projects or Boost configuration files?

Just add -static to your build invocation. Here is a quick example session:
$ cat boost_formatted_time.cpp #include <iostream> #include <boost/date_time/posix_time/posix_time.hpp> #include <boost/date_time/posix_time/posix_time_io.hpp> using namespace boost::posix_time; using namespace std; int main(int argc, char **argv) { time_facet *facet = new time_facet("%d-%b-%Y %H:%M:%S"); cout.imbue(locale(cout.getloc(), facet)); cout << second_clock::local_time() << endl; } $ g++ -o /tmp/bft_dyn boost_formatted_time.cpp -lboost_date_time $ g++ -static -o /tmp/bft_stc boost_formatted_time.cpp -lboost_date_time $ ls -lh /tmp/bft_* -rwxr-xr-x 1 edd edd 216K 2010-02-24 12:34 /tmp/bft_dyn -rwxr-xr-x 1 edd edd 1.5M 2010-02-24 12:34 /tmp/bft_stc $ /tmp/bft_dyn 24-Feb-2010 12:34:55 $ /tmp/bft_stc 24-Feb-2010 12:34:59 $ Note how the static binary is 1.5mb as opposed to 216kb for the dynamically-linked variant. All done on Debian testing with the default Boost packages.

Specify -Lpath/to/library/ to the linker.

I have no problems with a project build and library path, I just need to change the linking type: from dynamic to static.

That is not correct -- you need
-static. The -L gives the location of the library but not the linking type. See my answer for a full session.
