Conflict between two libraries QGui4.lib and qwt.lib

[RSousa]

Hello,

I 'm builting in a release mode and I had a linking problem:

1>QtGui4.lib(QtGui4.dll) : error LNK2005: "public: void __thiscall QWidget::resize(int,int)"
(?resize@QWidget@@QAEXHH@Z) already defined in qwt.lib(qwt_legend.obj)

They were compiled in release and Multi-threaded DLL modes...

It seems conflict between these two libraries...

I can´t remove one of them and I can´t remove the function from any of these libraries...

Could you help me, please...?

Thank you very much

All the best

if this is already defined in your qwt version, perhaps qwt is linked statically to qt?
Otherwise it must not be in there.

Thank you Gerolf

You are right.. I thought that the lib file was an import library.

I also tried to create an import library for qwt but I only got a .dll because I don´t have a the headers files __declspec definitions (implicit use of .dll). Is there any way to create a .dll without changing the header files?

Thank you very much again!

All the best
