@mrjj
Ans 1]
yes i t's for new project that i have copied .
Ans 2] i don't know about it i have just copy the project and try to build that project.
ans 3] its binary file i can not execute it

Note that : NEWAPP is target name in my .pro file

Well by new , i mean clean. default project generated with Creator.

Where did you copy it from ? Is it on the net ?

Im asking as this error often is

1: path or permission . Please delete the exe and make so its for sure generated again fully.
2: the .pro added LIPS += something that then can't be found at run time
3: the working dir path in project->RUN

So show me the output of an ls -l on it, to start with.

yes i t's for new project that i have copied .

Copied what from where how? For all I know, maybe it's an executable for a different architecture, or almost anything else....

Hi
It seems to have execute on
what happens if you do

./NEWAPP

to try start it ?

[Qt embedded developer]

@mrj output of ./NEWAPP: j can not execute binary file

1: path or permission . Please delete the exe and make so its for sure generated again fully.
Ans: i am using linux so its generate NEWAPP as binary and NEWAPP is target name .

Hi

try
objdump NEWAPP
and see what it says

I suspect you have an exe from other platform/bitness 32/64
like 64 bit app on 32 bit os
or reversed.

@Qt-embedded-developer
If NEWAPP does not run you could try looking at:

• file NEWAPP
• ldd NEWAPP

And you might have trouble trying to run a UI application as root....

Hi,

Why are you developing your application as root ?

That looks like your reason then!

NEWAPP: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.16,

And are you e.g. 32-bit LSB and ARM ? If you are not ARM on this machine....

@JonB Means i can not able to test changes i will make in project .

THANKS for help and answer @mrjj @JonB @SGaist

Hi

Ah so it was just wrong exe type.

You produce an ARM "exe" so most likely you are
supposed to copy it to some test board for running it.

Also if the board is connected and all is set up , Creator can transfer the exe to the board and run it
with debugger and all.

You should ask the other developers about it. What they do etc.
