Installing Qwt-6.0.0-rc4 on Windows

[Maduin]

Hey

I've installed Qwt-6.0.0-rc4 on Windows 7 (32) but still i only get "No such file or directory" when trying to include qwt headers. Im using Qt 4.7.0. Maybe you'll be able to help me, already spent few hours looking for a clear, simple Qwt instalation guide for a newbie.

Here's what i did step by step:
- Unpacked qwt to C:/Qt/qt/Qwt-6.0.0-rc4/ (C:/Qt/ is my qt dir)
- Changed qwtconfig.pri: win32 {
QWT_INSTALL_PREFIX = C:/Qt/qt/Qwt-$$QWT_VERSION-rc4
}
- removed QWT_CONFIG += QwtDll from said qwtconfig.pri
- started qt command line followed by changing dir to C:/Qt/qt/Qwt-6.0.0-rc
- qmake qwt.pro
- mingw32-make
- mingw32-make install

After that I created new project with included <qwt_plot.h>.
Added following lines to my pro file:

'LIBS += -lqwt \
-lqwtd
INCLUDEPATH += C:/Qt/qt/qwt-6.0.0/src
INCLUDEPATH += C:/Qt/qt/qwt-6.0.0/include'

The only result was "qwt_plot.h: No such file or directory". I'll be grateful for any advice on what am i doing wrong.

i did something similar,
but instead of mingw32-make
try nmake...

however, I got error 10077 not sure how to resolve it yet.
You can give that a try

I prefer using dll version of qwt that why my answer will not be helpful.

Latest versions of Qt support creating your own qmake features. After installing qwt your can only one following line in .pro file to use qwt without need to specify include and library paths:

CONFIG += qwt

CONFIG += qwt

To copy to clipboard, switch view to plain text mode 

In my case installing procedure next:
1. unpacked qwt source in any folder.
2. change qwtconfig.pri (almost like you did):
QWT_INSTALL_PREFIX = D:/Dev/Qt/Qwt-$$QWT_VERSION-rc4
3. from command line i execute

qmake
nmake
nmake install

qmake
nmake
nmake install

To copy to clipboard, switch view to plain text mode 

4. to use qwt's qmake custom feature, i created system environment variable called "QMAKEFEATURES = D:\Dev\Qt\Qwt-6.0.0-rc4"
5. after that qmake and qt creator works fine with .pro files with line "CONFIG += qwt"

Also, in your case there are some errors in .pro file.
1. qwt.lib and qwtd.lib are release and debug version of same library that why line "LIBS += -lqwt -lqwtd" is error
2. you make mistake in line "INCLUDEPATH += C:/Qt/qt/qwt-6.0.0/include". It must be "INCLUDEPATH += C:/Qt/qt/qwt-6.0.0-rc4/include"

Hi, Tarhan:
I also have problems with qwt installing.
Could you tell me in details how you did at step 4 (4. to use qwt's qmake custom feature, i created system environment variable called "QMAKEFEATURES = D:\Dev\Qt\Qwt-6.0.0-rc4"
) ? And why?

Thanks a lot.

I'm really tired of these postings, where someone has problems with something he has found in another posting, where someone ...

Instead read the INSTALL instructions, where you find the following link: http://doc.qt.nokia.com/4.7/qmake-ad...ation-features

Sorry, Uwe, but I am also following the instructions of the Qwt package, and however I was able to compile it, it is not an easy task to overcome the problems (e.g. using Qwt in Designer). It is not straightforward, and requires too high competence for understanding these parameters, tricks, etc. Better documentation could eliminate all these problems. Though, thank you for your support!

Sorry, Uwe, but I am also following the instructions of the Qwt package, ...

From your other posting it is obvious, that you are trying to build Qwt with the Creator. Sorry, but this is absolutely not following the instructions !

Qwt comes with a project files with default settings, that should be usable for common situations for your platform. The Qt creator overrules some of these settings from the command line, what might lead to a misconfiguration if you don't know what you are doing. Second you have to add "make install" as additional build step in the Creator. If you don't do this you don't have a proper installation.

You can use the Creator for building Qwt if you want to, but it offers absolutely no advantage and you have to solve problems ( no big ones, if you know your tool ) you wouldn't have without it.

It is not straightforward, and requires too high competence for understanding these parameters, tricks, etc.

Installing and using Qwt is straightforward and being able to read an INSTALL file + doing what you are told to doesn't count as "high competence". The first step is to build and install Qwt, the second step is to configure your project environment to use an installed version of Qwt.

For the first step there is absolutely nothing to document beside:

qmake
make
make install

qmake
make
make install

To copy to clipboard, switch view to plain text mode 

For the second step you need to read some Qt docs:

1) Tell qmake how to find the Qwt features file: see http://doc.qt.nokia.com/4.7/qmake-ad...ation-features

2) You have to tell the designer or creator, where to find the Qwt designer plugin: see: http://doc.qt.nokia.com/4.7/deployment-plugins.html

3) You need to help your program loader to find the Qwt library ( for loading your application, the designer/creator or any other executable using the Qwt library ). How to do it depends on the operating system ( on Windows it might be setting the PATH variable ).

1 and 2 are requirements of Qt and documented there. All required links can be found in the Qwt INSTALL file. 3 belongs to the basics every developer simply has to have.

Better documentation could eliminate all these problems.

Documentation can always be better, but in your case you didn't even read carefully what is there.
