[Qt 5.0.2] Build problems

irobot

Hi everyone.
When I create a project and I build it I get this error:
"MAKEFILE_GENERATOR variable not set as a result of parsing : myProject.pro. Possibly qmake was not able to find files included using "include(..)" - enable qmake debugging to investigate more."
I am on Windows 7 64

Are you using Qt creator to create the project?

irobot

yes i'm using Qt Creator.

Hi,

Could you show your myProject.pro ?

irobot

This is my .pro file

QT += core gui

-What OS are you on?- Just saw it is Windows 7.

I have scanned all files on my Qt folder (it is Qt 4.8.4) for "MAKEFILE_GENERATOR". This is just a settings in mkspecs/*.conf files basically declaring the OS you are on. For most it simply states "UNIX".

My guess is that there is a problem with the setup of Qt on your system. My recommendation is reinstall. Maybe someone else has a better idea.

Done but same problem

What IDE are you using ?

Did you try with the latest 5.1 ?

I just had thee very same errors when trying to build QtCreator 2.7.0 project when I entered the command qmake -r or somthing.

What I did to resolve that issue was the following (not sure exactly which one cured it)

Searched for where qmake was located (search your Qt install folder) and added that path to my %PATH%.
Installed perl from: "perl":http://www.activestate.com/activeperl/downloads
Installed GIT (I don't think you need to do this though).
Finally (and I am also not sure you need this, but you do to build QtCreator) searched for "sh.exe" on my PC and checked if any of those locations were in my %PATH% and removed them.

Probably step one is the most important I would think. Maybe you can just print your entire %PATH% variable to this post and we can take a look to see if there is anything obvious missing...

Of course, this may or may not be your issue... but it looks really similar to mine.

The other thing is: did you install Qt from the SDK (i.e. Qt SDK5.0.2) from here: "qt-sdk-5.0.2":http://qt-project.org/downloads
?

that would be the easiest way to get the whole package up and running (and un-install anything you had before...

code_fodder

update: Actually I just noticed that I don't think Qt/Qt SDK add themselves to your PATH variable, I think they setup their paths "on the fly". So just note that : ) - if you do add this to your path and it works, then I would not recommend leaving it like that incase there are some conflicts with other programs. If that is the problem then there is more an issue with your "local" paths when running Qt/QMake...

irobot

@SGalst I am using Qt Creator and Mingw and I didn't already try Qt 5.1 because I could face the same problem.
@code_fodder Yes

irobot

I don't know if it can be the problem origin: I also have Qt 4.8.1 installed in C harddisk and I want to install Qt 5.0.2 in E. Is it a problem?
Another thing is in Options > Build and run>Qt Version under the Autodetected block I have " ! Qt 5.0.2 MinGW 32bit E:\Qt\5.0.2\mingw47_32\bin\qmake.exe". If you have not noticed, I have an exclamation mark before Qt 5.0.2 and the MinGW is 32 bits is it a problem because I am on Windows 7 64 bits?
Thanks to all.

No problem using MinGW 32 bit version on Windows 64 bit. I have installed MinGW 4.6.2 32 bit on windows 7 64 bit without problems.

The exclamation mark is probably displayed as an icon. IIRC it should give some explanations when you click on it.

irobot

No it's the yellow one not the red.

SGaist

Anyway, it should give you an hint on what is wrong when clicking on it. If not, ensure that the details panel is hidden.

Without the information provided when clicking on the exclamation mark icon, there's only the crystal ball solution or try to install your Qt on the C drive.

irobot

Sorry I said it in my last post:
@
Version name: Qt 5.0.2 MingW 32bit
qmake location : C:\Qt\Qt5.0.2\5.0.2\mingw47_32\bin\qmake.exe
qmlscene not installed
qmlviewer not installed
@
And I already install it on my C drive.

SGaist

When I first read your last post it said "Other solutions ?"

Anyway, unless you're doing qml projects, they are not vital to the development. Can you move your projects in a folder path without any spaces ?

There have always been problems with handling spaces in path.

irobot

I moved it. Same problem.
