Please refer to the image at :
I use MinGW,QT and CMake for my project.
As shown in the figure, my project has two modules.
* libRinzoCore.DLL : a shared library which define some abstract classes and
interfaces and some core functionality of the application.This module is
used to implement dynamic Plugins (which are also shared libraries which
automatically loaded by the application) .
* Rinzo.exe : the main application.This uses "libRinzoCore" classes.
"libRinzoCore" mainly developed using QT objects and link against the QT
"Rinzo.exe" also uses QT library objects,some are not being used in
"libRinzoCore".So I have to link QT Library and "libRinzoCore" with this
I can compile "libRinzoCore" without problems and it generated two files
"libRinzoCore.DLL" and "libRinzoCore.DLL.a"
But during compiling "Rinzo.exe" it gives the following output :
Linking CXX executable Rinzo.exe
Info: resolving IRzPlugin::staticMetaObject by linking to
Info: resolving IRzViewerPlugin::staticMetaObject by linking to
Info: resolving IRzLayeringPlugin::staticMetaObject by linking to
warning: auto-importing has been activated without --enable-auto-import
specified on the command line.
This should work unless it involves constant data structures referencing
from auto-imported DLLs.
[100%] Built target Rinzo
And when executing "Rinzo.exe" it crashes with the message (this is a
translation from Japanese error message)
But in linux (with GCC) with works fine.
What is the error message?
You can fix those auto-import warnings by using proper dllimport/dllexport for your classes.
