QwtPolar building generates an error on qwtpolard.lib

[bouchebeu]

Hello everyone,

I'm building qwtpolar1.1.0-rc0 on Win7 64bits.
I'm using Qt5.1.1 and Qwt6.1.0, both built with msvc2012.

When launching the command nmake inside the qwtpolar folder (where I launched a qmake qwtpolar.pro before), I get the following error :

LINK : fatal error LNK1104: impossible d'ouvrir le fichier 'qwtpolard.lib' (Read : impossible to open file qwtpolard.lib)

Same error but with qwtpolar.lib when I execute the command nmake release

I checked in the qwtpolar/lib folder : I only find qwtpolar.dll and qwtpolard.dll.
No *.lib

Does anyone know the solution to this annoying error ?

Thanks !

Link qwtpolard.dll instead of qwtpolar.lib.

Thanks for your answer;

I tried to link one of the example in qwtpolar (polardemo) with the dll using the line

# I'm not shure it's the right way, but I found it on some forum
LIBS += "C:/Dev_x86/qwtpolar/QwtPolar-1.1.0-rc0/lib/qwtpolard.dll"

in the .pro, but it tries to open the 'qwtpolard.lib'.

I might not have understood your advice; could you please extend your answer ?

Thanks

if it helps, the line following line in example.pri is evaluated to false.

contains(QWT_CONFIG, QwtPolarDll)

Is your question about how to link your application statically or how to link at all ?

Uwe

[bouchebeu]

It's just about linking the library (preferably dynamicallly)

In fact, it's a 2 steps question :

1. The QwtPolar doesn't compile (actually, it stops at the linkage; and when it does, only qwtpolar.dll and qwtpolard.dll are created in the /lib folder)
2. I can't link the polardemo example to these dll (But since the qwtploar[d].lib don't exist, will it work ? I thought that a .lib was needed to link with a dll)

Thanks

[Uwe]

When you can't even build the libraries better report this first.

Uwe

[bouchebeu]

Ok; I wen't on the sourceforge 's project page and created a ticket there.

[Uwe]

No I mean you should disable the silent mode in qwtpolarbuild.pri rebuild the project and show more information about what fails.

Uwe

[bouchebeu]

Hi, I did remove the silent mode, but I just get the same message.

What I did was also remove the designer from the 'qwtpolar.pro' file (I commented the 3 corresponding lines).
(Maybe the designer is needed for the whole building process to work...?)

And the error I get is :

where the line:

means

LINK : fatal error LNK1104: impossible to open 'qwtpolard.lib' file

If it helps, in the qwtpolar-1.1.0-rc0/lib folder, there are 8 created files:

qwtpolar.dll
qwtpolar.dll.embed.manifest
qwtpolard.dll
qwtpolard.dll.embed.manifest
qwtpolard.dll_manifest.rc
qwtpolard.dll_manifest.res
qwtpolard.ilk
qwtpolard.pdb

Added after 1 41 minutes:

Update; I now uncommented the designer lines I commented before in qwtpolar.pro.
I still have the same problem.

[bouchebeu]

Hello again,

I tried with the newly released Qt.5.2.0-beta version, and I still have the exact same error.
I'm really stuck and don't know where to investigate.

Thanks for any ideas.

Don't you follow your own ticket: http://sourceforge.net/p/qwtpolar/bugs/4/ ?

Oups...

Thanks.
