What is the error " 'cl' is not recognized as an internal or external command, operable program or batch file" means?

[pratik041]

I am trying to run my code and i am getting this error. What may be the fault?

[koahnig]

you need to provide some details on the environment you are using (OS, IDE, compiler, etc)

[pratik041]

os is window xp sp2, Qt Creator 2.2.1 based on qt 4.7.4, msvc2008

[koahnig]

cl is the command to start your compiler. There must be something broken for this setup.

I assume there is at least a problem with the environment for the failing project.

Is it just this project you cannot compile?
If you other projects using similar setup, you need to to check, if those are compiling.

[pratik041]

other project is working fine.

[andre]

Your environment for this project is somehow not setup properly.

[pratik041]

ok can you say why this happens?

[koahnig]

I expect as Andre that your project is somehow not setup properly. However, we need a crystal ball to understand thoroughly with the little information we have.

I would suggest to set up a new project and see if this is compiling properly. Possibly this was only one occassion. If not, you probably have to check the installation of qt creator.

[pratik041]

ok now it is working

[andre]

Could you explain what was wrong, so others may learn from it as well?

[pratik041]

actually i don't able to find what was the problem. i have just restarted my system after that it was working.
