• How to reduce compile time with C++ templates

  - by Shane MacLaughlin

  I'm in the process of changing part of my C++ app from using an older C type array to a templated C++ container class. See this question for details. While the solution is working very well, each minor change I make to the templated code causes a very large amount of recompilation to take place, and hence drastically slows build time. Is there any way of getting template code out of the header and back into a cpp file, so that minor implementation changes don't cause major rebuilds?
