QWT is missing files

**Jore** · 17th February 2010, 15:36

Hi there

When building QWT i miss the file qmemarray.h as included in qwt_array.h written by josef wilgen and uwe rathmann

"#ifndef QWT_ARRAY_H
#define QWT_ARRAY_H

#include "qwt_global.h"

/*!
\def QwtArray
Aliases QArray (Qt-2.x) and QMemArray (Qt-3.x) to QwtArray
*/
#ifdef QWT_NO_MEMARRAY
#include <qarray.h>
#define QwtArray QArray
#else
#include <qmemarray.h>
#define QwtArray QMemArray
#endif

#endif"

Anyone who knows where I can find a complete release of QWT as the one at SOURCEFORGE is incomplete?
Or, even better, anyone who knows where I can download QWT.DLL compiled for WIN32 on mingw (g++)?

Looks like you have an old version of qwt. Try this one: qwt-5.2.0

Hi Norobro!

Thank you for trying to help me!

I think you mean 4.2.0 and that's the version I'm using
(link goes to qwt-4.2.0-setup-qt230nc.exe)

The way I'm building my qwt.dll the 4.2.0 release is missing include files

Probably I'm building it all wrong.
After setting path and qmakespec I write
qmake qwt.pro
make

as instructed by INSTALL txt file.

The last row in the install file was obviously put there for a reason.
The last row states
"Good luck !"
Luck is what I need right now :-)
"If it wasn't for bad luck, I would have no luck at all" ;-)

Now I'll go and experiment with nmake instead

I just wonder, why can I not build QWT.DLL in QT Creator?
Would not that be really neat feature.

I've found and tried to build 5.2
(aiming at make install)

But building in qt4.6.1 QT Creator 1.3.1 generate error
c:/tools/Qt/2010.01/qt/include/QtCore/../../src/corelib/tools/qhash.h:875: error: call of overloaded 'qHash(const double&)' is ambiguous

trying comand line so far without luck
exit with same error as qt creator, ambiguous call

Does this mean that I have to downgrade QT?
To what version??
Appears that 4.6.1 does not play football with neither 5.2.0 nor 4.2.0
