Problem in debugging qt program

koahnig

where do you run nmake?
Outside of the msvc using a simple command prompt?

Amirhosein

yes
I use simple command prompt and not VS command prompt

SGaist

I might be wrong, but I think that using a MSVC2010 Qt with VS2008 might be problematic

koahnig

This is probably the reason for your problem.
When you are compiling Qt libs with nmake and msvc compiler you have to start the command prompt through VS. It will not work with the standard command prompt. VS is setting apparently something in the environment.

I have never tried, but I would guess that the same rules apply when use nmake directly. Give it a try.
AFAIK there is no way around the VS command prompt.

That is for sure too. You cannot mix different msvc versions.

You can if you setup the environment by hand, it can even work from an msys prompt (i.e. installed with git for windows) but that's not for the faint hearted.

IIRC, there are several batch files you can use to setup a command prompt. They can be found in the VS install, or the quick way is to check the properties of the various command prompt shortcut in the Start menu

Well, I was never digging as deep. I was doing a couple of compilations of Qt 4 versions. All I know is that one had to use msvc command prompt. That was the officially recommended way to do the compilation based on msvc for quite some time. However, that might have changed over the time.

However, the problem or an additional problem is probably the mix of different msvc versions. The libs of msvc were always dependent of the compiler versions.

Since msvc2008 is used and no pre-build of msvc2008 is on the official page, that is for sure the next thing to check.

IFAIK, it hasn't changed a bit, I did that to automate release builds and I like bash better.

Completely agree

Amirhosein

Thank you very much for your help

I will try to solve the problem with your solution on Monday at work and then if I still have this problem, we can try to find another solution.

As your information, I tried the later versions of visual studio but the result was same. I prefer to use MSVC 2008 because it is in English and others are in german. anyway, thanks again for your help.

The open question at the time is whether you have installed the correct Qt lib version. The version has to be compiled with the same MSVC version as you are trying to do your application.

Which version of Qt are you using?
Is it Qt5 or Qt4?
Where did you download from?

Amirhosein

I use Qt v4,8,4 (VS2010 Opensource). I don't know from where it is downloaded.

when I call nmake in command prompt, it gives me same fatal error for both of MSVC that I have. Maybe my MSVCs have a problem.

These are the errors:

C:\Program Files\Microsoft Visual Studio 9.0\VC>nmake

NMAKE : fatal error U1064: MAKEFILE not found and no target specified
Stop.

C:\Program Files\Microsoft Visual Studio 10.0\VC>nmake

NMAKE : fatal error U1064: MAKEFILE nicht gefunden und kein Ziel angegeben
Stop.

SGaist

You have both Visual Studio 2008 and 2010 installed ?

Amirhosein

yes I have the both.

koahnig

If you want to use Qt libs 4.8.4 (VS2010 Opensource) you must use the compiler tool chain shipped with msvc2010 for compilation.

"According to this":http://de.wikipedia.org/wiki/Microsoft_Visual_Studio#Version_2010 it would be the second one you have tried.

This seems to be correct nmake, but the makefile is missing.

Do you use msvc2010 as IDE (integrated development environment) or Qt creator?

I got the feeling that you are working on command prompt only. Is that true?

Anyway a qmake run is missing. This would create the missing makefile.

Amirhosein

I don't have Qt creator, so I only use command prompt.

so you think that my Qt has a problem?

SGaist

No, what koahnig said is that you probably didn't run qmake, so you don't don't have a Makefile because of that.

To build your project (and I recommend a shadow build)

make a shadow build folder besides your source folder

cd into that folder

call qmake ..\mycoolprogram\mycoolprogram.pro

call nmake

Amirhosein

of course I built my project with qmake, but I got an error that I posted before,
I think I should try the new versions of Qt which has also Qt creator but does Qt5,1 that released recently work with MSVC 2010 or I should also install the later version of VC?

SGaist

What do you have in the folder where you ran qmake ?

Amirhosein

Hello.cpp
Hello.pro
Makefile
Makefile.debug
Makefile.release
release and debug folder which are emoty.

Sorry, for criss-crossing with SGaist. Certainly, he is correct that you should be able to do all from command prompt. If you think that is the better way, that is fine.

However, I think using an IDE helps to get all required steps in the right order.

If you have a fully licensed MSVC2010 version (not the express version which is for free), you can install vsaddin or maybe you have that should take care of calling qmake and nmake in the right sequence.

An alternative is using Qt creator and your "only" choice when you have only an msvc express version.

You do not have to switch to Qt 5 for using Qt creator. You install from the download page the Qt5 SDK which includes Qt creator. This will allow you also to continue to use Qt4.8.4 libs as already installed. However, you "waste" a bit of HD space, but have already Qt5 too.
Alternatively, you can install "Qt creator":http://download.qt-project.org/official_releases/qtcreator/2.8/2.8.0/qt-creator-windows-opensource-2.8.0.exe separately from download page.
