Problem using Qt Charts <QtCharts/QAbstractSeries> Not found

Jenifer

Hi, I have downloaded QtChars source code from "https://github.com/qt/qtcharts " .
I am able to run qmake. But when i try to BUILD the source code from QtCreator , i am getting error as
No such file or directory found : #include<QtCharts/QAbstractSeries> . I am using Qt 5.6 version .
I am new to Qt programming, i want to build a application to show graphs so any kind of help would be greatly appreciated. Thank you

Hello,
Could you provide a bit more? What is the precise error you get from the compiler, in which file and at which line? Do you get errors/warning in the General messages window inside Creator? How exactly are you trying to build the module, have you tried building from the command line?

Kind regards.

Hi and welcome to devnet,

To add to @kshegunov, what OS/Compiler are you working with ?

Jenifer

@kshegunov : I have tried from the command line as well. The error says QtCharts/QAbstractSeries: No such file or directory . #include<QtCharts/QAbstractSeries> , this error prompts from src/charts/chartdataset.cpp file.
I get the same error on command line as well as on Qt Creator

@SGaist : I am working on windows 7 OS and mingw49_32 compiler.

@Jenifer
Perhaps a silly question, but when you cloned the repository did you select the correct branch (Qt version)?

Kind regards.

SGaist

You should also clone from code.qt.io. Github is just a mirror.

Jenifer

@SGaist
Ya i tried to clone it from code.qt.io. this was mentioned in other threads too. But i got the following error "The requested URL /qt/qtcharts.git was not found on this server." So i cloned it from Github.

@kshegunov
Ya it seems silly too , but i am unable to resolve it. I have selected the correct branch and qt version.
I am completely new to QT so i have no clue how to resolve it. I tried checking the .pro files as well but i couldn't figure out what is causing that error.

SGaist

Can you show the line you used to clone the repository from code.qt.io

How are you trying to build the project ?

Jenifer

@SGaist
I tried with

git clone https://code.qt.io/qt/qtcharts.git
git clone http://code.qt.io/qt/qtcharts.git
git clone git://code.qt.io/qt/qtcharts.git

I get the error as
fatal: unable to access 'https://code.qt.io/qt/qtcharts.git/': Couldn't resolve host 'code.qt.io'.

I tried building the project from QtCreator it showed the error as mentioned above. Later i tried from command prompt and got the same error

@Jenifer

Try this:

git clone -b 5.6 git://code.qt.io/qt/qtcharts.git

Then you try building. Go in the cloned directory and run (put the correct paths here):

/path/to/qt/qmake
mingw32-make

Finally if everything goes well you can install in the (preset) location with:

mingw32-make install

By the way, did you build Qt yourself, or you have installed it with the maintenance tool?

Kind regards.

Jenifer

@kshegunov

Even after using this command
git clone -b 5.6 git://code.qt.io/qt/qtcharts.git

The error persist
fatal: unable to access 'https://code.qt.io/qt/qtcharts.git/': Couldn't resolve host 'code.qt.io'.

I have installed it from the maintenance tool.

@Jenifer
I'm sorry, this error:

fatal: unable to access 'https://code.qt.io/qt/qtcharts.git/': Couldn't resolve host 'code.qt.io'.

does not correspond to the suggested git command. Are you sure you're executing what I wrote and not something else? I can pull the repository without a problem.

Kind regards.

Jenifer

@kshegunov

Sorry,

When I use this command
git clone -b 5.6 git://code.qt.io/qt/qtcharts.git

I got the following error
Unable to look up code.qt.io (port 9418) (No such host is known. )

So i tried it with
git clone -b 5.6 http://code.qt.io/qt/qtcharts.git
git clone -b 5.6 https://code.qt.io/qt/qtcharts.git
commands for which i got the error as
fatal: unable to access 'https://code.qt.io/qt/qtcharts.git/': Couldn't resolve host 'code.qt.io'

SGaist

Are you behind a firewall ? A custom DNS ?

Jenifer

@SGaist
Yes there is firewall . Will that affect ??

SGaist

Check with the people responsible to manage it but it's likely that it's blocking access to code.qt.io

Jenifer

@SGaist
Thank you i will check with the concerned people and get back if any help needed
