I use vs2003 toolkit,and met this question before ,my reason for this is path error,you should make boost 'include ' dir in vc2003 and system enviroment -----邮件原件----- 发件人: boost-users-bounces@lists.boost.org [mailto:boost-users-bounces@lists.boost.org] 代表 DC 发送时间: 2006年11月17日 14:19 收件人: boost-users@lists.boost.org 主题: [Boost-users] Newbie problems resolving header paths I downloaded 1_33_1 and it built and installed. Actually, I'm still not sure what is meant by "install" in the docs. Does something happen than copying a bunch of files to C:\Boost ? VC71 is having trouble resolving paths to the headers. I have: In the project properties, Additional Include Directories: C:\Boost\include\boost-1_33_1; In my .cpp file, I use, for example: #include <boost/date_time/gregorian/gregorian.hpp> I still get: C:\Dev\VS2003\MyProject\Engine.h(3): fatal error C1083: Cannot open include file: 'boost/date_time/gregorian/gregorian.hpp': No such file or directory Hoping I'm overlooking something simple here.
