Hello! Guys,

I am new to Qt GUI Design. Recently i tried to do a small and simple project in which i developed metric.pro file, main.cpp file & form.h file. After all this i used qmake command to create makefile and then make to create its executable.Ya i am working on linux.

But the main problem is whenever i try to run my application i am not able to run my application.
Its showing me "command not found error".

Can anyone please help me out in this stuff. I will be obliged if helped please.....

Thanks in Advance.

But whenever i try to run "metric" it says "command not found" i dont know why! For informing i am working on linux with Qt3.1.2 version. Please help me buddy.

I will be obliged------>Thanks in advance.

Thanks Bargi !
The command which i used to run my application is: - first i went to directory where my project file is i.e. Convert & then i used "qmake -o Makefile metric.pro". Then i used "make" command to get its executable. Finally i used "metric" to run the application.

Below is the output screen of the terminal: -

abcdxyz:~1)> cd Convert
abcdxyz:~/Convert2)> qmake -o Makefile metric.pro
abcdxyz:~/Convert3)> make
g++ -o metric .obj/main.o .obj/conversionform.o .obj/qmake_image_collection.o .obj/moc_conversionform.o -L/usr/lib64/qt-3.1/lib -L/usr/X11R6/lib64 -lqt-mt -lXext -lX11 -lm
abcdxyz:~/Convert4)> metric
metric: Command not found.
abcdxyz:~/Convert5)> ./metric

Hello! Bargi,
Thanks buddy it worked but i still have a problem.

I have Linux & Windows on my system wherein i have installed Qt in Linux. As far as i know the developed application is platform independent & should work in any platform but my application works only in Linux. The executable doesn't work in Windows. Also in Windows even the file is not shown as executable. Why is it so? Please help me out in this stuff.

I will be obliged if helped. Thanks cery much in advance.
