[Nel] precompiled header file

[zen]

Hi all!

 

I don't know whether gcc support precompiled header or not, but VisualC++ do support it. So, I suggest the VC++ workspace setting take advantage of this. I've make some experiment on the 'misc' project. The compiling time drop from 2 minutes to 1 minute and 30 seconds, reduced about 25% , not bad.

 

And in case you don't know how to set precompiled header file support, these are the steps:

1. Add to the project a .h file, e.g stdafx.h, which #includes those common header files, particularly STL header files .

2. Add a dumb .cpp file, e.g stdafx.cpp, which do nothing more than #include "stdafx.h".

3. Change project setting, in 'C/C++' tab 'Precompiled Headers' set it to 'Use precompiled header file [.pch]' through header: stdafx.h.

4. Change the setting of stdafx.cpp to 'Create precompiled header file [.pch]'.

5. Add every .cpp file a line #include "stdafx.h".

6. recompile.

 

Hope this would be helpful.
