Hi, this is my first time to use Boost -librairies. I have created a Project folder where in my complete Software architeture is available. I have placed boost libraries downloaded from boost.org site within INCLUDE dir of VC 2005 Install directory. However I received many compilation errors. Can anyone help me to resolve these errors. Am I doing the right thing to get the CPP Software to compile. List of Errors I have received are here by ------ Build started: Project: vc2005_mcf52xxinit, Configuration: Debug Win32 ------ Compiling...
