https://github.com/qt/qtcloudmessaging example does not compile

[sierdzio]

OK code looks good, no idea why it does not work.

[SGaist]

Hi,

What compiler are you using ?

[Ilnur]

@SGaist

[SGaist]

That doesn't fully answer the question. What version of gcc are you using ?
Are you using Qt Creator to build the module ?

[Ilnur]

here I also have one more problem, firebase/app.h not found
May be I installed module incorrectly?
What I did:

/qt_dir/path_to_android_qmake/qmake CONFIG+=firebase
make
sudo make install

no, I built via terminal

qmake CONFIG+=firebase
make
sudo make install

[SGaist]

Might be a silly question but did you install the firebase SDK ?

Hello, I would like to start the qtcloudmessaging example!
I followed the instructions on qtcloudmessaging-examples
Can you help me with this?

This is the error "Project ERROR: Unknown module(s) in QT: cloudmessagingfirebase"

`cd firebase\ && ( if not exist Makefile D:\Qt\5.12.5\mingw73_64\bin\qmake.exe -o Makefile C:\Users\rjung\Desktop\Beispiel-Projekte\Push-Projekte\qtcloudmessaging-examples-master\firebase\firebase.pro -spec win32-g++ "CONFIG+=debug" "CONFIG+=qml_debug" "CONFIG += firebase" ) && D:/Qt/Tools/mingw730_64/bin/mingw32-make -f Makefile clean

Before I add this in qmake:
"CONFIG += firebase"

Because I am not allowed to set my environment variables, I added the path for GOOGLE_FIREBASE_SDK in .pro file:
GOOGLE_FIREBASE_SDK = <Path_to_Firebase_SDK>

isEmpty(ENV_FIREBASE_SDK) {
ENV_FIREBASE_SDK = $${GOOGLE_FIREBASE_SDK}
...

Hi,

Did you build the module itself ? With firebase support ?

[Robin Hood]

This post is deleted!

[Robin Hood]

So i've been building a firebase project under firebase console.
I downloaded the qt project from git (https://github.com/snowgrains/qtcloudmessaging-examples) and followed the instructions. Basically i just changed some paths and added the google-service.json ...

But I think I must have forgotten something in the front if qt does not recognize the module.

[SGaist]

Hence my question: did you build that Qt module ?

[Robin Hood]

I don't know...
How would you build Qt modules?

[Robin Hood]

I think ...
In the manual (https://github.com/snowgrains/qtcloudmessaging-examples) I did it until step 3. Step 4 is not applicable for me, because I only want to use firebase.

But step 5 does not work. I think this is the problem, which is why he doesn't know the module.

Step 5 is:
Install first the QtCloudMessagingfrom command line with:
qmake "CONFIG += embedded-kaltiot firebase" make make install

I tried that, but the command does not work on my Windows computer.

C:\Users\...\Desktop\Beispiel-Projekte\Push-Projekte\qtcloudmessaging-examples-master>qmake "CONFIG += embedded-kaltiot firebase" make make install
Der Befehl "qmake" ist entweder falsch geschrieben oder
konnte nicht gefunden werden.

Afterwards I tried it like in the Qt Creator ...

C:\Users\...\Desktop\Beispiel-Projekte\Push-Projekte\qtcloudmessaging-examples-master>D:\Qt\5.12.5\mingw73_64\bin\qmake.exe C:\Users\...\Desktop\Beispiel-Projekte\Push-Projekte\qtcloudmessaging-examples-master\cloudmessaging.pro -spec win32-g++ "CONFIG+=debug" "CONFIG+=qml_debug" "CONFIG += embedded-kaltiot firebase" && D:/Qt/Tools/mingw730_64/bin/mingw32-make.exe qmake_all
Info: creating stash file C:\Users\...\Desktop\Beispiel-Projekte\Push-Projekte\qtcloudmessaging-examples-master\.qmake.stash
Project ERROR: Cannot run compiler 'g++'. Output:

===================
Maybe you forgot to setup the environment?

[jsulm]

@Robin-Hood Use the qtenv2.bat script from your MinGW installation to set up the environment properly.

[Robin Hood]

@jsulm said in https://github.com/qt/qtcloudmessaging example does not compile:

I changed this file

@echo off
echo Setting up environment for Qt usage...
set PATH=D:\Qt\5.12.5\mingw73_64\bin;D:/Qt/Tools/mingw730_64\bin;%PATH%
set GOOGLE_FIREBASE_SDK=C:\Users\name\firebase_cpp_sdk_6.14.0\firebase_cpp_sdk
cd /D D:\Qt\5.12.5\mingw73_64

I still get the error message on the console

C:\Users\...\Desktop\Beispiel-Projekte\Push-Projekte\qtcloudmessaging-examples-master>D:\Qt\5.12.5\mingw73_64\bin\qmake.exe C:\Users\...\Desktop\Beispiel-Projekte\Push-Projekte\qtcloudmessaging-examples-master\cloudmessaging.pro -spec win32-g++ "CONFIG+=debug" "CONFIG+=qml_debug" "CONFIG += embedded-kaltiot firebase" && D:/Qt/Tools/mingw730_64/bin/mingw32-make.exe qmake_all

as well as in qt-creator

"Project ERROR: Unknown module(s) in QT: cloudmessagingfirebase"

[jsulm]

@Robin-Hood said in https://github.com/qt/qtcloudmessaging example does not compile:

I changed this file

Why? There is no need to change this file.
And did you execute that file?
As you can see it still fails to find the compiler.

[Robin Hood]

Then I had it wrong. I reversed the change.

But after executing it the same problem with the modules. Look here:

D:\Qt\5.12.5\mingw73_64\bin>qtenv2.bat

[SGaist]

You first have to download and build the qtcloudmessaging module.

[Robin Hood]

I have followed the instructions so far, but I haven't read anything about it.

Where can I find the download for the qtcloudmessaging module and how do I build it in detail.

I need a little more support here.
