0xc0000005 when linking against lib

[jacek]

Did you compile that library in release or debug mode? Do you use the same mode for your application?

[niko]

i did build both in debug mode.

and tried both in release-mode too - doesn't help.

[niko]

I attached my files, perhaps someone would like to help and see if he can reproduce the problem
(or - better - tell me what i'm making wrong)

steps to reproduce:

unpack attached zip
set CPPLIBS=absolutepath to libs-dir (used by qmake-scripts)
cd libs
qmake
make
cd ..
cd PetManager
qmake
make
debug\PetManager

cd libs
qmake
make
cd ..
cd PetManager
qmake
make
debug\PetManager

I think it works:

<object class="Pet" name="" >

Hallo

(I use PLD Linux and Qt 4.1.1).

Did you buld those libraries as static ones or as DLLs? Did you try to copy all DLLs to the directory where your executable is?

[niko]

much thanks for testing!
(how bad it works for you... probably only a problem on win32?)

[qoute]Did you buld those libraries as static ones or as DLLs? Did you try to copy all DLLs to the directory where your executable is?[/quote]
as dll (the standard-behaviour)

...and yes - i copied the dlls into the direcotory.

[jacek]

Yes, I just checked the sources and all classes are declared like this:

class DataObject : public QObject {
    Q_OBJECT
    // ...
};

class DataObject : public QObject {
    Q_OBJECT
    // ...
};

To copy to clipboard, switch view to plain text mode 

Which means that they aren't ready for use in DLLs (in short: you can't use those classes outside the DLL, because they're not exported).

It should be:

class EXPORT DataObject : public QObject {
    Q_OBJECT
    // ...
};

class EXPORT DataObject : public QObject {
    Q_OBJECT
    // ...
};

To copy to clipboard, switch view to plain text mode 

Where EXPORT macro is either __declspec(dllimport), __declspec(dllexport) or empty. See this thread for more info.

aaah, much thanks for that hint!

i compiled the libary now static and everything is working just fine!

big thanks!
