[Solved] Simple initializer problem

franku

Additionally you could run qmake again.

If you want to be clear which code is used by the preprocessor you want to use a statement like this:

@#error "Simple"@

But I don't understand why you define the EXPORT and the IMPORT macro when using only the EXPORT in your class definition.

Hi franku,

You are right, but DEFINES qmake adds the values of this variable as compiler C preprocessor macros (-D option). So, when I add the line:
@# interface_mngr.pro
DEFINES +=
INTERFACEMNGRLIB_LIBRARY@

it add

@#define INTERFACEMNGRLIB_LIBRARY@

Thank you for your time.

PD: When create shared lib follow this "link":http://doc.qt.nokia.com/4.7-snapshot/sharedlibrary.html#header-file-considerations

Hi, I know. This is the reason why I asked you to rebuild your makefiles using qmake. Just to be shure having the -D commandline parameter being passed to the compiler. Read the contents of the link again carefully to see where the difference is to your code.

You can use the #error to stop the preprocessor if you want to know which line is really evaluated.

I have found a strange issue:

I delete all references to InterfaceMngr in the file core.h and core.cpp, and found that the library compile without errors, but when I try to use it, give the compile error referenced here before.

Shouldn't it be:

@
#if defined(INTERFACEMNGRLIB_LIBRARY)

define INTERFACEMNGR_EXPORT Q_DECL_EXPORT

#else

define INTERFACEMNGR_EXPORT Q_DECL_IMPORT

#endif
@

otherwise, INTERFACEMNGR_EXPORT will not be defined when you try to use the exported symbol.

Hi Arnold,

I have other two similars definitions but don't have any problem.
The libraries "ModuleMngr":https://github.com/thanatosJSSE/Sipred/blob/master/src/managers/module/modulemngr.h and "PluginMngr":https://github.com/thanatosJSSE/Sipred/blob/master/src/managers/plugin/pluginmngr.h.

Thank you.

In both pluginmngr_global.h and modulmngr_global.h the declaration looks like this

@
#ifndef PLUGINMNGR_GLOBAL_H
#define PLUGINMNGR_GLOBAL_H

#include <QtCore/QtGlobal>

#if defined(PLUGINMNGRLIB_LIBRARY)

define PLUGINMNGR_EXPORT Q_DECL_EXPORT

#else

define PLUGINMNGR_EXPORT Q_DECL_IMPORT

#endif

#endif // PLUGINMNGR_GLOBAL_H
@

which is exactly what i suggested.

Regards,

If i am not wrong there is a missing ";" after Q_DECLARE_PRIVATE(InterfaceMngr):
@
private:
Q_DECLARE_PRIVATE(InterfaceMngr) ; //here

};
@

Thanatos.jsse

That's right, interfacemngr have his own interfacemngr_global.h.

And this looks like you suggest.

There is no problem, I tried that too, without results.
I found that this library is compiled, but when I try to use it give me that error.

Ok,

Thank everyone that helped me to take a look to mi code.
Well the problem was a personal mistake:

@#if defined(INTERFACEMNGRLIB_LIBRARY)

define INTERFACEMNGR_EXPORT Q_DECL_EXPORT

#else

define INTERFACEMNGR_IMPORT Q_DECL_IMPORT <---- ERROR!!!

#endif@

Must be EXPORT like Arnold said

BR,
