How to use a class who has SHAREDEXPORT in 'direct' mode?

[tonnot]

I explain it.
I have a class part of mydll (it works ok)
ok, I want to use the .h and .cpp files of this class individually in 'pure' or 'direct' way , but I have two elements that are the guilty it does not work :
1.- The .h file has an include to global.h (where I define the SHARED_EXPORT sufix)

#include <QtCore/qglobal.h>
    #define ACLASSSHARED_EXPORT Q_DECL_EXPORT
    etc

#include <QtCore/qglobal.h>
    #define ACLASSSHARED_EXPORT Q_DECL_EXPORT
    etc

To copy to clipboard, switch view to plain text mode 

2.- The class it self (.h) that has 'ACLASSSHARED_EXPORT Aclass' name .

When I wnat to use in my project I have several errors an undefined references.
If I want top use it I have to duplicate the files and to delete the #include global.h and the 'ACLASSSHARED_EXPORT' sufix.

Is there a way to avoid this ?
Can I use a qmake variable to say 'If you are in dll environmet use it' if not, dont.
(or something like this?)
Thanks (I hope you can understand what I want)

can you post the full export defines of ACLASSSHARED_EXPORT?
You should have an #ifdef statement there, that changes the export to import depending if you are building the DLL or linking against it.
It seems this is not quite correct in your case.

This is the code for acore_global.h

#ifndef ACORE_GLOBAL_H
#define ACORE_GLOBAL_H
#include <QtCore/qglobal.h>
#if defined(ACORE_LIBRARY)
#  define W_FILESSSHARED_EXPORT Q_DECL_EXPORT
#  define W_UTILESSHARED_EXPORT Q_DECL_EXPORT
#  define W_QTUTILSHARED_EXPORT Q_DECL_EXPORT
#  define W_ASCIISHARED_EXPORT Q_DECL_EXPORT
#  define W_XMLSHARED_EXPORT Q_DECL_EXPORT
#  define W_CONFIGSHARED_EXPORT Q_DECL_EXPORT
#else
#  define W_FILESSSHARED_EXPORT Q_DECL_IMPORT
#  define W_UTILESSHARED_EXPORT Q_DECL_IMPORT
#  define W_QTUTILSHARED_EXPORT Q_DECL_IMPORT
#  define W_ASCIISHARED_EXPORT Q_DECL_IMPORT
#  define W_XMLSHARED_EXPORT Q_DECL_IMPORT
#  define W_CONFIGSHARED_EXPORT Q_DECL_IMPORT
#endif
 
#endif // ACORE_GLOBAL_H

#ifndef ACORE_GLOBAL_H
#define ACORE_GLOBAL_H
#include <QtCore/qglobal.h>
#if defined(ACORE_LIBRARY)
#  define W_FILESSSHARED_EXPORT Q_DECL_EXPORT
#  define W_UTILESSHARED_EXPORT Q_DECL_EXPORT
#  define W_QTUTILSHARED_EXPORT Q_DECL_EXPORT
#  define W_ASCIISHARED_EXPORT Q_DECL_EXPORT
#  define W_XMLSHARED_EXPORT Q_DECL_EXPORT
#  define W_CONFIGSHARED_EXPORT Q_DECL_EXPORT
#else
#  define W_FILESSSHARED_EXPORT Q_DECL_IMPORT
#  define W_UTILESSHARED_EXPORT Q_DECL_IMPORT
#  define W_QTUTILSHARED_EXPORT Q_DECL_IMPORT
#  define W_ASCIISHARED_EXPORT Q_DECL_IMPORT
#  define W_XMLSHARED_EXPORT Q_DECL_IMPORT
#  define W_CONFIGSHARED_EXPORT Q_DECL_IMPORT
#endif

#endif // ACORE_GLOBAL_H

To copy to clipboard, switch view to plain text mode 

and filess.h is

#ifndef W_FILESS_H
#define W_FILESS_H
 
#include "Acore_global.h"
class W_FILESSSHARED_EXPORT W_filess
{

#ifndef W_FILESS_H
#define W_FILESS_H

#include "Acore_global.h"
class W_FILESSSHARED_EXPORT W_filess
{

To copy to clipboard, switch view to plain text mode 

This is a piece of my dll that works fine.
How can I use filess.h in another project but not in dll ? (That is, just including the files with #include)
. Have I to write another thing at Acore_global.h ?
Thanks

Change the file containing the macro definitions so that if a particular macro is defined (or not), W_FILESSHARED_EXPORT expands to nothing.

BTW. Moving to General Programming, this has nothing to do with Qt. Next time please think which forum is the best to post a particular question.

[tonnot]

Thanks Wysota but ... How I do that ?

[wysota]

The same way you did with ACORE_LIBRARY.

[tonnot]

Thanks
I'm going to re-read the Qt help regarding this.

[wysota]

Qt help has nothing to do with this. This is strictly a C++ (or even cpp) issue. You know how #ifdef and #define work, right?

[tonnot]

Thanks Wy.
Ok, it works with :

#ifndef ACORE_GLOBAL_H
#define ACORE_GLOBAL_H
 
#include <QtCore/qglobal.h>
 
#if defined(ACORE_LIBRARY)
#  define W_FILESSSHARED_EXPORT Q_DECL_EXPORT
#  define W_UTILESSHARED_EXPORT Q_DECL_EXPORT
#  define W_QTUTILSHARED_EXPORT Q_DECL_EXPORT
#  define W_ASCIISHARED_EXPORT Q_DECL_EXPORT
#  define W_XMLSHARED_EXPORT Q_DECL_EXPORT
#  define W_CONFIGSHARED_EXPORT Q_DECL_EXPORT
#else
    #if defined(ACORE_DIRECT)
    #  define W_FILESSSHARED_EXPORT
    #  define W_UTILESSHARED_EXPORT
    #  define W_QTUTILSHARED_EXPORT
    #  define W_ASCIISHARED_EXPORT
    #  define W_XMLSHARED_EXPORT
    #  define W_CONFIGSHARED_EXPORT
    #else
    #  define W_FILESSSHARED_EXPORT Q_DECL_IMPORT
    #  define W_UTILESSHARED_EXPORT Q_DECL_IMPORT
    #  define W_QTUTILSHARED_EXPORT Q_DECL_IMPORT
    #  define W_ASCIISHARED_EXPORT Q_DECL_IMPORT
    #  define W_XMLSHARED_EXPORT Q_DECL_IMPORT
    #  define W_CONFIGSHARED_EXPORT Q_DECL_IMPORT
    #endif
#endif
#endif // ACORE_GLOBAL_H

#ifndef ACORE_GLOBAL_H
#define ACORE_GLOBAL_H

#include <QtCore/qglobal.h>

#if defined(ACORE_LIBRARY)
#  define W_FILESSSHARED_EXPORT Q_DECL_EXPORT
#  define W_UTILESSHARED_EXPORT Q_DECL_EXPORT
#  define W_QTUTILSHARED_EXPORT Q_DECL_EXPORT
#  define W_ASCIISHARED_EXPORT Q_DECL_EXPORT
#  define W_XMLSHARED_EXPORT Q_DECL_EXPORT
#  define W_CONFIGSHARED_EXPORT Q_DECL_EXPORT
#else
    #if defined(ACORE_DIRECT)
    #  define W_FILESSSHARED_EXPORT
    #  define W_UTILESSHARED_EXPORT
    #  define W_QTUTILSHARED_EXPORT
    #  define W_ASCIISHARED_EXPORT
    #  define W_XMLSHARED_EXPORT
    #  define W_CONFIGSHARED_EXPORT
    #else
    #  define W_FILESSSHARED_EXPORT Q_DECL_IMPORT
    #  define W_UTILESSHARED_EXPORT Q_DECL_IMPORT
    #  define W_QTUTILSHARED_EXPORT Q_DECL_IMPORT
    #  define W_ASCIISHARED_EXPORT Q_DECL_IMPORT
    #  define W_XMLSHARED_EXPORT Q_DECL_IMPORT
    #  define W_CONFIGSHARED_EXPORT Q_DECL_IMPORT
    #endif
#endif
#endif // ACORE_GLOBAL_H

To copy to clipboard, switch view to plain text mode 

And DEFINES +=ACORE_DIRECT in the .pro file.
Thanks.
A last question :
I use in my .pro:
INCLUDEPATH += mypath
DEPENDPATH += mypath
So, I can write code and QTknows where the class I'm using are, but it does not compile.
(Only compile if I add the files for the class to my project)
What more I need?

[wysota]

You need to tell your compiler you wish to have those classes compiled or linked into you project.
