Static compile of Qt Charts

Jedd

Got it. Compiled qtcharts and copied the .a file to my static 5.8, then added:

LIBS += -lQt5Charts

To my .pro file.

SGaist

QT += charts should be enough in your .pro file

Jedd

Great, thanks for your replies!

I have come across the same problem. I have a fully working dynamic build but have now tried a static build of Qt. However, after successfully building Qt statically and try to run, I get the following error:

:-1: error: Unknown module(s) in QT: charts datavisualization help

Apologies if this is a basic question, but could you please explain (for dummies) how to "build the module by hand"?

Edit: to complete a static build, I ran:

configure -opensource -confirm-license -static -platform win32-g++ -opengl desktop -prefix "C:\Qt\5.12.6\mingw73_64_static" -skip webengine -nomake tests -nomake examples
...
mingw32-make
...
mingw32-make install
...
mingw32-make clean

@AhmedAlshawi hi, if you don't have QtCharts as part of your sources, you have to first download it.

Then the classic qmake/make/make install applies. Note that I recommend using out of source builds.

@SGaist Thanks for the quick reply. I must admit I do not understand what the 'classic qmake/make/make install' means.

I downloaded the sources package as part of the installation for Qt, and within my sources folder 'Src' I do have the 'qtcharts' folder, but I do not have 'qthelp' or 'qtdatavisualisation' in the folder.

To build, should I copy the 'qtcharts' folder out of 'Src' and then build it? and how do I 'build' it?

Thanks a lot!

SGaist

No, the idea is to create a folder outside of the source tree and do the build there.

For example:

mkdir -p /Users/jedd/build/qtcharts
cd /Users/jedd/build/qtcharts
/path/to/your/self_built/Qt/bin/qmake /path/to/qtcharts
make
make install

AhmedAlshawi

@SGaist So I followed the steps exactly and I get an error that 'make' can't be found.

Here are the lines added into PATH

Thank you :)

SGaist

I wrote for a *nix OS.

In your case it's "mingw32-make".

AhmedAlshawi

@SGaist Amazing thank you!! Worked a treat!

I now still get 'datavisualization' and 'help' as unknown modules, but I can't find these in the 'Src' folder. Can I download them separately or are they hidden somewhere?

Also, when I try and build my project using this static build, I have added "CONFIG += static" to the .pro file, but get these two errors:

:-1: error: Cannot find windeployqt.exe in "C:\Qt\5.12.6\mingw73_64_static\bin".
Cannot find winrtrunner.exe in "C:\Qt\5.12.6\mingw73_64_static\bin"

Any help is much appreciated. Cheers.

SGaist

The help module likely comes from qttools as well as windeployqt.

All the sources should be available from the installer, but if not, then you can clone them from https://code.qt.io

@SGaist
Thank you so much, I built qttools in the same way and it fixed my problem completely!
