Hi all, I am having trouble linking against Boost DLLs. Even though I think I am using the correct compiler commands, I seem to end up with statically linked binaries (everything works fine, but Dependency Walker shows that I have no DLL dependency on Boost). Specifically, I am trying to link against Boost:Serialization. Because I'm using MinGW, my Boost libraries had to be compiled by me, so I used "bjam --toolset=gcc --layout=system". I then ran "bjam install" with the same options, which resulted in (over 1GB of) files in c:\Boost. Next I build my own program. It compiles against the Boost files using GCC parameters "-IC:\Boost\include" and then links against Boost::Serialisation using "-LC:\Boost\lib" -lboost_serialization-mt So, what can I do to set GCC to use dynamic linking to the DLL in this case, instead of the static linking that it appears to be using at the moment? (I am a little unclear about the purpose of the .a files currently present in the c:\Boost\lib directory. Do they refer in some way to the DLLs or are they self-contained static libraries?) Cheers JP
