Undefined reference when Gcc compiling Boost::regex with multiple versions of boost exist?

Maybe it's because in your compile command, you said to use my_path/boost-1.49.0/include/boost as include path and then, in your source code you include.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
