Hello, I am not very experienced with boost. I try to learn how to use the boost.thread library. After early bjam compilation errors (undefined references, because the boost_thread library was not linked), I found that this Jamroot creates my executable successfully: exe threadtest : threadtest.cpp : <library>/usr/lib/libboost_thread-gcc42-mt-1_34_1.so.1.34.1 ; Is it possible to simplify the <library> parameter to something like "boost_thread"? The reason is that I am developing on different systems with different boost versions, so that I don't want to hardcode the library version in the Jamroot. I thought that the boost.build system should be smart enough that it finds the appropriate library file if you only tell it "use the thread library please". How can I make the Jamroot independent from the boost installation and, more importantly, from the operation system? Best wishes, A. Kalaghan
