cannot run: no command

[Asha]

Good Morning guys,

Any suggestions please..

@asha "how to install qt creator on ubuntu 18.04" - either install one delivered with Ubuntu using apt-get, or download QtCreator from official website.
"which version qt is required" - you should know that. Which version do you want to use, or which version is supported by your SDK?
"which version cross-compiler is required" - the one provided by the SDK for your device.
"how to install that one" - should be part of the SDK.
"how to install debugger also" - should be part of the SDK.

Thankyou for the replay,

I done the same things..

then also getting permission denied error while running the qt application..

trying to login ssh root@192.168.7.2 there also same error permission denied..

not getting what is the problem..

@asha said in cannot run: no command:

trying to login ssh root@192.168.7.2 there also same error permission denied..

So, you actually can't login using SSH?
Then you first need to solve this problem.
Looks like root is not allowed to login via SSH on this device.
Do you have other users there?
Also, see https://www.cyberciti.biz/faq/howto-limit-what-users-can-log-onto-system-via-ssh/

[Asha]

yes I have other user as debian, through "ssh debian@192.168.7.2" I am able to login in target machine.

[jsulm]

@asha Then either use that user or enable root login via SSH

[Asha]

Hi,

I login via debian user

then enabled the root login /etc/ssh/sshd_config file

here is the running status

now I am able login as a root

So, I changed the directory /opt permissions here "chmod go+wx opt"

after this all, restarted the system ,and open the qt and run the simple application, the result is

So now what is the problem...any idea about this...(Thankyou very much)...

@asha You did not cross compile your app for your device.
You can verify this by doing (in a terminal):

file PATH_TO_YOUR_EXE

and checking its output.

[Asha]

can you give example,for more understanding purpose

[jsulm]

@asha You open a terminal and type "file" followed by the path to the executable file you built and press enter...
For more information see "man file".

[Asha]

Hi,

the result after typing "file /usr/lib/qt5/bin/qmake"

[Asha]

what it means,how to processed next.

[jsulm]

@asha Why qmake?
It is about your app (beagle) which is created if you build your app.

[Asha]

,

I build the application(beagle)but i dont no where exactly the location of executable.

[Asha]

Hi,

Sorry,now got the build beagle executable,please go through this one

how to processed next.

[jsulm]

@asha Your binary is for x86-64 as you can see. What is your device CPU? I guess ARM?

[Asha]

yes it is ARM

[jsulm]

@asha Then you did NOT cross compiled your app.
Is your Kit for the device configured properly?
It has red exclamation mark.

[Asha]

Then which cross compiler I have to use,

when go on kit beagleboard its displaying the details ,in that showing

Error:The compiler "cross_compiler"(arm-linux-generic-elf-unknown)cannot produce code for the qt version "Qt 5.13.0 GCC 64 bit"(x86-linux-generic-elf-64bit).

[jsulm]

@asha You need cross compiled Qt. Qt you're currently using is compiled for x86 as error says. You can't use x86 binaries on ARM.
