I enabled PCH for one project. Added all commonly used headers(from C++ std lib and boost) into stdafx.h, added stdafx.cpp and included stdafx.h there. I selected Create in the properties of stdafx.cpp and selected Use in the project settings. Also I added stdafx.h in the /FI option - to avoid including stdafx.h in every unit.
When I rebuild the whole project, it firstly complies stdafx.cpp and the quickly the other *.cpp files - it's OK, and it seems to be working. But if I change a file and then build the project, it takes lots lots of time to recompile that single file, comparably with rebuilding the whole project, so it seems that PCH doesn't work, or it rebuilds PCH file, or what?
What do I do wrong?
