Hi I am using STLPort 5.2.1 and Boost1_40_0 with MSVC 9.0. I have successfully compiled boost libs with STLPort and am using the Graph, filesystem and DateTime libraries. I use dynamic linking of STLPort libs. All the projects build and run fine. Today I started looking at the serialization library and just compiling the basic demo threw a 100 linker errors. All the paths for boost libs and STLPort binaries are correct. This is on a 64 bit system. When i ran the same code for serialization on a 32 bit box it compiled and ran fine. Is there some setting I am missing for 64 bit systems? Thanks -- View this message in context: http://www.nabble.com/linker-error-with-Boost-serialization-on-64-bit-box.-W...
