Well... Bummer. In the latest version of the Toto test project, i was actually
using __stdcall. But still...
This is from TotoLib.h:
#ifndef TotoLib_h
#define TotoLib_h
#include "TotoLib_Global.h"
class TotoLibOpt TotoLib {
public:
/**/ TotoLibOpt __stdcall TotoLib ();
};
#endif
This is from TotoLib.cpp:
#include "TotoLib.h"
#include <QtCore/QDebug>
__stdcall TotoLib::TotoLib() {
qDebug() << "It worked!";
}
TotoLib_Global.h looks like this (TotoLibExport is only defined when compiling
the lib):
#ifndef TotoLib_Global_h
#define TotoLib_Global_h
#if defined(TotoLibExport)
# define TotoLibOpt __declspec(dllexport)
#else
# define TotoLibOpt __declspec(dllimport)
#endif
#endif
After compiling, gendef extracts this (I think the result is the same with /
without --assume-stdfcall):
; Definition file of TotoLib.dll
; Automatic generated by gendef
; written by Kai Tietz 2008
LIBRARY "TotoLib.dll"
EXPORTS
_ZN7TotoLibC1Ev@4@4
_ZN7TotoLibC2Ev@4@4
Then, i create the delay import library with:
dlltool --dllname TotoLib.dll --input-def TotoLib.def --output-delaylib
libTotoLib.delayed.a TotoLib.dll
And i create a simple program which instanciates a TotoLib object from the
library:
#include <../TotoLib/TotoLib.h>
int main (int argc, char *argv[]) {
TotoLib t;
}
It won't link!!

Am i missing something? i feel like i have done exactly what you are telling me
to try, no?
Thanks,
Pierre.
