How to solve MAKEFILE_GENERATOR variable not set as a result of parsing: ... error ?

Hasibul Hasan Chowdhury

Hi,

Recently I have installed qt 5.8 android version in windows 10 64 bit pc. After open my projects which was worked fine in qt 5.5, now give this error when compile
16:23:10: Running steps for project DatabaseTutorial...
16:23:10: Starting: "G:\IDE\Qt5.8.0\5.8\mingw53_32\bin\qmake.exe" "G:\PROJECTS\Qt Projects\DatabaseTutorial\DatabaseTutorial.pro" -spec win32-g++
MAKEFILE_GENERATOR variable not set as a result of parsing : DatabaseTutorial.pro. Possibly qmake was not able to find files included using "include(..)" - enable qmake debugging to investigate more.
16:23:10: The process "G:\IDE\Qt5.8.0\5.8\mingw53_32\bin\qmake.exe" exited with code 3.
Error while building/deploying project DatabaseTutorial (kit: Desktop Qt 5.8.0 MinGW 32bit)
The kit Desktop Qt 5.8.0 MinGW 32bit has configuration issues which might be the root cause for this problem.
When executing step "qmake"

The following define makes your compiler emit warnings if you use

any feature of Qt which as been marked as deprecated (the exact warnings

depend on your compiler). Please consult the documentation of the

deprecated API in order to know how to port your code away from it.

DEFINES += QT_DEPRECATED_WARNINGS

You can also make your code fail to compile if you use deprecated APIs.

In order to do so, uncomment the following line.

You can also select to disable deprecated APIs only up to a certain version of Qt.

#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000 # disables all the APIs deprecated before Qt 6.0.0

SOURCES += main.cpp
mainwindow.cpp

HEADERS += mainwindow.h

please help me immediately. Thanks.

@Hasibul-Hasan-Chowdhury "please help me immediately" - this is a forum where volunteers are answering questions, you should not expect to get answers immediately.

"The kit Desktop Qt 5.8.0 MinGW 32bit has configuration issues which might be the root cause for this problem" - please check the Kit you're using: any errors/warnings?

Also "Desktop Qt 5.8.0 MinGW" is NOT Qt for Android!

Hasibul Hasan Chowdhury

Thank you sir. I am have installed qt-opensource-windows-x86-android-5.8.0.exe this version. and I get this error when compile any projects.

jsulm

@Hasibul-Hasan-Chowdhury "G:\IDE\Qt5.8.0\5.8\mingw53_32\bin\qmake.exe" - you are not using Qt for Android as you can clearly see in this line. You're using Qt 5.8 MinGW - it is NOT for Android.
Did you check the Kit as I suggested?

Hasibul Hasan Chowdhury

@jsulm I get one error QMainWindow not found in my header file. I am building for windows not for android. but my package was qt-opensource-windows-x86-android-5.8.0.exe. thanks.

jsulm

@Hasibul-Hasan-Chowdhury "kit: Desktop Qt 5.8.0 MinGW 32bit" - is definitely not for Android.
Did you include QMainWindow header file?

#include <QMainWindow>

Hasibul Hasan Chowdhury

OK. if Qt 5.8.0 MinGW 32bit not for android. How to build my project for both windows and android ? What version should I download ? But if i install qt 5.5 it works fine. Where is the problem ?

jsulm

@Hasibul-Hasan-Chowdhury The Kit you are using now is for Windows. You should use Qt Online Installer. Then you will have Qt Maintenance Tool which you can use to easily install all needed Qt versions - for example Qt for Android. For Android you need more than just Qt, see http://doc.qt.io/qt-5/androidgs.html

Regarding your problem: I asked in my previous posts some questions. You still did not answer. So, again:

Check the Kit: are there errors or warnings?
Did you include QMainWindow header file?

#include <QMainWindow>

Hasibul Hasan Chowdhury

@jsulm Yes sir. I include it into header file. But it show a red circle and say QMainWindow not found.

jsulm

@Hasibul-Hasan-Chowdhury But are you able to build?

jsulm

@Hasibul-Hasan-Chowdhury Also if you changed Qt version you should delete the build directory, run qmake again and then build.

Hasibul Hasan Chowdhury

@jsulm No. When I hit the build button, I get this

jsulm

@Hasibul-Hasan-Chowdhury This is not the same as "QMainWindow not found". Something is wrong with your .pro file or Kit (you still not checked it as I suggested). Is it possible to upload your project to somewhere and post link here, so I can download it and check?

Hasibul Hasan Chowdhury

@jsulm Wait for me sir. I am sending screenshots and details.

Hasibul Hasan Chowdhury

@Hasibul-Hasan-Chowdhury I can not upload the screenshots in this forum. I am adding whole code for you.

I have checked kit and I found

@Hasibul-Hasan-Chowdhury Does your .pro file really contain comments without # character at the beginning? It should be like this:

TARGET = DatabaseTutorial
TEMPLATE = app
#The following define makes your compiler emit warnings if you use

Regarding yellow warnings: keep mouse cursor over the Kit - you will see then what the problem is.

Hasibul Hasan Chowdhury

@jsulm yes

@Hasibul-Hasan-Chowdhury Remove all the comments or comment them out
