Compile and use Qwt in qt|vs2017

Last time QT Use in QWT Set histogram with different colors , So how do we configure it ？

Next, let's explain how to qt Middle configuration QWT as well as QWT The compiler problem of ！

Usage environment ：VS2017(64 position )、QWT(6.1)、Qt5.14.2

QWT The download address of is

link ：QWT Download link

The website was previously used svn Download the , Such a page , as follows ：

however , Now it's updated qwt Website , Not shown above , You don't have to download it first svn 了 .

Click in the red area to download directly ~

This download is time-consuming .

After downloading , Use VS2017 open qwt.pro File for compilation , There are other words on the Internet , It's using qmake, I think it's safer without this method .

Start by opening VS2017 after , Click the following location to load the project

load qwt.pro file , At this time, a problem will be found after opening the project qwt_designer_plugin Items are gray and unavailable ！

here , Need to put  qwtconfig.pri  Under the document  QWT_CONFIG += QwtDesigner  Shielding

#QWT_CONFIG += QwtDesigner

Reopen the project to resume compilation .

Compile separately debug and release edition , Will be compiled dll as well as lib Place them in Qt5.14.2 Under the folder

1： take qwt-6.1 Under the document lib in  qwtd.dll、qwt.dll Put it in  D:\Qt\Qt5.14.2\5.14.2\msvc2017_64\bin Under the table of contents

2： take qwt-6.1 Under the document qwtd.lib、qwt.lib Put it in D:\Qt\Qt5.14.2\5.14.2\msvc2017_64\lib Under the table of contents

3： take qwt-6.1 Under the document  E:\qwt-6.1\designer\plugins\designer  in qwt_designer_plugin.lib、qwt_designer_plugin.dll Store in  D:\Qt\Qt5.14.2\5.14.2\msvc2017_64\plugins\designer Under the table of contents

4： take qwt-6.1 The document added src In the document .h as well as .cpp file   Put it into a new QWT In the folder , Put this folder in D:\Qt\Qt5.14.2\5.14.2\msvc2017_64\include in

Create a new project to test . First, configure the attributes

1： attribute -> Configuration properties ->C/C++--> routine , Attach include directory ：$(QTDIR)\include\QWT

2： attribute -> Configuration properties -> The linker -> Input , Additional dependency ：qwtd.lib （debug The configuration ）

3： attribute -> Configuration properties -> The linker -> routine , Additional Library Directory ：$(QTDIR)\include\lib

4： attribute -> Configuration properties ->C/C++-> The preprocessor , Preprocessor definition ：QWT_DLL

QWT The compilation of and the configuration in the project are updated here ~
