Hi, I built the thread library after downloading "boost_1_36_0.zip". After building the thread library from bjam, when I build the program in VS2008, I get following linker error:- Error 1 fatal error LNK1104: cannot open file 'libboost_thread-vc90-mt-gd-1_36.lib' What I see in the generated library folder is that boost_thread-vc90-mt-gd-1_36.lib is generated, but the linker is looking for 'libboost_thread-vc90-mt-gd-1_36.lib'. I have already done the required changes in the project properties mentioned at http://www.boost.org/doc/libs/1_36_0/more/getting_started/windows.html . Similar thing happening with Regex library also. The generated lib is boost_regex-vc90-gd-1_36.lib, but the linker is looking for libboost_regex-vc90-gd-1_36.lib. Is there any other settings change required or something else? Thanks, Bhargav.
