使用boost :: serialization与库链接时，编译时间很长

Question

Hello and thanks for reading.

I have a dynamic library using boost::serialization with about 200 different classes. I use this library in my program, thanks to the header messageExports.h, which looks like this :

#include "classe1.h"
//...
#include "classe200.h"

BOOST_CLASS_EXPORT(ns::classe1);
//...
BOOST_CLASS_EXPORT(ns::classe200);

But the file including messaeExports.h needs a really long time to compile, and this each time I modify it. As I am using Qt and qmake, i tried the PRECOMPILED_HEADERS method but it took a lot more time than without, and it seems qmake adds the precompiled header to each obj file.

Do you have idea how I could reduce my compilation time ? Is it possible to rearrange the messageExport.h header to avoid the boost export defines ?

Thank you in advance,

Roland

Seeing sample code would probably help, but...

Can you remove common, boilerplate code from "classe*.h" easily?

Use include guards to prevent multiple includes of the same file?

// File: ---classe1.h---
#ifndef __CLASSE1_H_INCLUDED
#define __CLASSE1_H_INCLUDED
// Stuff goes here
// Here
// Here (ad naseum)
#endif // __CLASSE1_H_INCLUDED
// End Of File: ---classe1.h---

Just a few suggestions...
