"mainwindows" Example

[Seth]

Hi All,

trying to run the "mainwindows" example that came with Qt 4.2.3

These complied okay
qmake -project
qmake mainwindows.pro

Choked when I ran
make

Shouldn't I be able to just run this program strait from its folder?

What file can I attach to show you the errors?

Thanks in advance

[wysota]

What do you mean by "choked"? And why did you run "qmake -project"? Didn't the example already have a project file?

[Seth]

Wysota, Yes, the example did have the -project file already in the folder. I ran it because thats how I did the tutorial examples, "hello", etc...

Did I cause a mishap by re-running"qmake -project"?

Choked I mean, the command prompt had like 100's of lines of gibberish. No .exe showed up in the DEBUG folder.

Is there a "log" somewhere so I can attach to show you the 100's of lines of gibberish.

Using the word "gibberish" because I dont know what all the lines mean on the command prompt.

You can attach a file to your post...
It's the "Manage attachements" button below...

Marcel, thanks but how do I pull (copy/paste) the data from the command prompt?

Is there some sort of "log" file that is generated that shows all the data (text) from the command prompt when "make" is executed?

[marcel]

Yes, actually...
When running qmake to compile th example do this:

qmake ... > qmake_output.txt

EDIT: "..." stands for the actual options that you would give to qmake

This will generate the file qmake_output.txt in the same folder. It means it will direction the console output to a file.
You can attach that.

[marcel]

Also, qmake hast the "-o file" option. The output will be written to the file you specify .

Marcel,

Iteresting, I just ran "qmake" instead of "make" and didnt get any errors or gibberish.

However, in the DEBUG file there is no .exe file to launch the program. The DEBUG file is empty.

How do we launch a program? Shouldnt there be a .exe file somewhere?

No where in the "mainwindows" folder was a file generated called "qmake_output.txt"

Attached is a qmake file, dont know if you can use it for debugging

Thanks in advance

[marcel]

Were you using make? Not good...qmake projects are not compatible with normal makefiles.
Check the Release folder for the executable...

[marcel]

The release folder in every folder in the mainwindows example...

regards

[Seth]

The RELEASE folder is empty as well.

Why cant I use "make"? I used it for the "hello" program and such.

[marcel]

If you want debugging information. add CONFIG += qt debug.
to use the plain, old make, you'll have to qmake -o Makefile mainwindows.pro ( sorry about before, -o is not for log ).
After this you can use make. As I said, a .pro file is not the same with a makefile( different syntax for start ).

[Seth]

Marcel, I am so new to programming.

What is [HTML]add CONFIG += qt debug[/HTML] and where do I add that?

Also, what is [HTML] -o [/HTML] and where do I add that?

Also, why arent I seeing an executable anywhere?

When I ran "qmake" on the command line it didnt give me errors so I should have seen an executable somewhere, correct?
