Aquileo | #4 QwtPolar building generates an error on qwtpolard.lib

Sun, 06 Mar 2022 23:24:05 -0000

I am coming back 10 years in the future. I am also experiencing the problem "impossible to open file qwtpolard.lib". I am compiling on windows with QT5.15.2 and MSVC2019. When trying the compilation with MINGW8, everything works well. I do not understand and if you have a fix, I would be happy.
Thanks for your help.
Best

The qwtpolar project has become part of the qwt library and the code you find in this repository won't be maintained anymore. Try this branch: https://svn.code.sf.net/p/qwt/code/branches/qwt-6.2 it will become the official Qwt 6.2 release pretty soon ( maybe next week ).

I am trying to make/install QwtPolar on a Windows 10 system. On the nmake I get the following error:

NMAKE : fatal error U1073: don't know how to make '......\Qt\Qt5.14.1\msvc2017_64\include\QWidg3ts\qfiledialog.h

Can you provide any insight to this issue?

Aquileo | Compile error in qwt_polar_renderer.cpp when QT_NO_PRINTER is defined

Fri, 14 Jun 2019 06:01:47 -0000

I was able to successfully configure, build and install Qwt for x86 and CE6 (cross-compilation) based on Qt 4.8.4.
To cross compile for CE6 I must define QT_NO_PRINTER macro (maybe QPrinter is not supported in CE6 - I don't know).
I was able to successfully configure, build and install QwtPolar for x86 too.

When I try to cross-compile QwtPolar for CE6 I must define QT_NO_PRINTER macro but this gives compile error in qwt_polar_renderer.cpp.
.\qwt_polar_renderer.cpp(231) : error C2027: use of undefined type 'QPrinter'
I see that some portion of the code in this file is conditionally excluded based on QT_NO_PRINTER macro.
But QwtPolarRenderer::renderTo() expected a QPainter inpt parameter in any case.

The solution is to include the whole function inside a #ifdef QT_NO_PRINTER directive.

Maybe polardemo example needs a fix too, because MainWindow::printDocument() in mainwindow.cpp instantiates a QPrinter variable
