Github actiosn migration - QWT not found error

[MaximumTrainer]

I'm in process of renovating an existing QT application & having received the source code I've added it to a github actions routine for cross platform builds.
However I am getting the a QWT not found error for my Linux & OSX build & can't figure out why (probably due to my lack of QT experience), any advice would be appreciated.


build.yml
https://github.com/MaximumTrainer/MaximumTrainer/blob/master/.github/workflows/build.yml

pro build file
https://github.com/MaximumTrainer/MaximumTrainer/blob/master/PowerVelo.pro

Linux error -

Github actions full output:

Note the windows build fails for a different reason which I will fix after this issue is resolved.

Thanks for your advice

Qwt is not part of the standard Qt distribution. It is an open-source library. You will have to download and build it for your platforms. You will also have to check which version of Qwt your app uses - Qwt 5 or Qwt 6. They are not compatible.

[MaximumTrainer]

Thanks & I thought that was the case.
In the build.yml I install QWT for OSX & Linux prior to triggering qmake & make, either via brew or apt-get, is this correct?

I can see you install Qwt 6 and its dev package into Ubuntu. This installs the qwt.prf file in a standard location (not /resources/qwt) that should be found by qmake without any modification of QMAKEFEATURES.

I am not familiar with the Github environment, so I am not sure what effect jurplel/install-qt-action is supposed to have in addition to the Linux setup you have already done. It seem to me that jurplel/install-qt-action (https://github.com/jurplel/install-qt-action) has no provision for qwt.

[MaximumTrainer]

Yes I agree that jurplel/install-qt-action may be overriding the manual install of qt & qwt.
Here is the build output when I remove jurplel/install-qt-action from build.yml -


Linux


Run qmake -set QMAKEFEATURES /resources/qwt/
qmake -set QMAKEFEATURES /resources/qwt/
qmake PowerVelo.pro
shell: /bin/bash -e {0}
Info: creating stash file /home/runner/work/MaximumTrainer/MaximumTrainer/.qmake.stash
/home/runner/work/MaximumTrainer/MaximumTrainer/PowerVelo.pro:6: 'versionAtLeast' is not a recognized test function.
Project ERROR: Use at least Qt version 5.12
Error: Process completed with exit code 3.

looking into this it appears that QT 5.9.5 was installed, so I have just adjusted the pro file build for the moment

Mac

Run qmake -set QMAKEFEATURES /resources/qwt/
qmake -set QMAKEFEATURES /resources/qwt/

Error: Process completed with exit code 127.

Reading this implies a path issue to me.


In my latest build I have removed jurplel/install-qt-action as this is causing a conflict & here are the latest errors -

Linux


Run qmake -version
QMake version 3.1

Mac this is back to the qwt not found error, not sure if this is as brew install qwt6 by default

The versionAtLeast() qmake function you are using does not exist before Qt 5.10, which explains the "not recognized test function" message out of Qt 5.9. Something like this should work under any version of Qt 5


equals(QT_MAJOR_VERSION, 5):lessThan(QT_MINOR_VERSION, 9) {
message("Cannot use Qt $${QT_VERSION}")
error("Use Qt 5.9 or newer")
}


I am focusing on the Linux environment (do not have a Mac)

You explicitly install most of Qt from a PPA that installs it under /opt/qt512 (qt512base qt512tools qt512serialport qt512svg qt512multimedia qt512connectivity qt512webengine qt512charts-no-lgpl qt512networkauth-no-lgpl qt512translations)
The PPA page (https://launchpad.net/~beineri/+archive/ubuntu/opt-qt-5.12.0-bionic) advises:

Source /opt/qt512/bin/qt512-env.sh to set the correct environment.
I suspect if you arranged this before you called qmake you would have Qt 5.12

The Qwt libraries you install are from the Ubuntu repository (libqwt-qt5-dev libqwt-qt5-6), and these install into locations for the generic system Qt version. They are probably responsible for pulling in enough of Qt5.9 to satisfy qwt (you see this in the log file). The feature file installed by this version (i.e. qwt.prf) will not be visible in the Qt 5.12 install

As I see it, you have two options:
1. Use the Ubuntu system Qt, Qt Charts, Qt Web Engine and Qwt and build using Qt 5.9
2. Use the PPA Qt 5.12, which includes everything except Qwt, and work out how to build Qwt and install for that version of Qt in the GitHub environment.

Thanks for the advise, I have now downgraded to QT 5.9. Looking at the Linux build this was causing multiple problems as I was using ACT locally (to simulate github actions) which I have now resolved, resulting in a Linux code compiling & erroring in a consistent was as my local environment.
I will now work through this & figure out the mac & windows issues.

Thanks
