You usually don't need to specify the boost lib, that is done automatically depending on your project settings. For dynamic linking you also need to have a .lib file. But this time the .lib file only contains functions declaration, but no implementation. Those are in the DLL. Does that help? Greets, Christian On 8/3/05, John Smith wrote:

I have been trying to use Boost Date_Time library with my code. I used boostjam to compile the source; the command used was: bjam -s"TOOLS=vc-7_1" --with-date_time install. The following libraries were built (among others): boost_date_time-vc71-mt-1_32.dll 45,056bytes boost_date_time-vc71-mt-1_32.lib 26,164bytes libboost_date_time-vc71-mt-1_32.lib 521,764bytes

boost_date_time-vc71-mt-gd-1_32.dll 77,824bytes boost_date_time-vc71-mt-gd-1_32.lib 26,312bytes libboost_date_time-vc71-mt-gd-1_32.lib 1,380,694bytes

My project is setup as follows: Runtime Library: Multi-threaded Debug DLL (/MDd) Additional Include Directories: $(BOOSTHOME)\include\boost-1_32 Additional Library Directories: $(BOOSTHOME)\lib Additional Dependencies: boost_date_time-vc71-mt-gd-1_32.lib

Using the above setup I could only link if the static library (libboost_date_time-vc71-mt-gd-1_32.lib) was also available. If not, I kept getting LINK : fatal error LNK1104: cannot open file 'libboost_date_time-vc71-mt-gd-1_32.lib' However, when this file is available, I am able to link and use the DLL (checked DLL usage using depends.exe).

Does this make sense? I was under the impression that I should only need the import library. Also, how does it know the name if the library?

Thanks.
