Deploy and start app at Raspberry Startup

Amaury

Hi there,

I'm actually develloping an app on my raspberry Pi 3 I need this app to start on Rasp startup, I did not find any solutions that worked for me do you have any clue , or is there anything to do in QT t oset this up .

By the way I'm running rasbian.

Hi
There is nothing in Qt you must do extra as compared to any other .exe you want to run at startup
https://www.raspberrypi.org/forums/viewtopic.php?p=142242

However, I trust u can run the app on the pi and its just the issue of running it at startup ?

Amaury

I can run the app by using the RUN button in Qt I never tried to launch by using .exe cause I don't know how to do this, I mean I already looked at deplying an application but I'm not able to start from .exe is there any command that I should run ?

If I can handle that , I could launch my app by using the .exe at startup.

Hi
First you should be able to run the app outside Creator.
I assume PI OS acts like any other linux.
So you need a deployment folder with the Qt run times files. DLL/so files

http://www.tripleboot.org/?p=138
section Linux GCC 32-bit and 64-bit compilers:

Pay huge attention to what dlls/so files u copy. DO NOT mix debug and release.

If the OS is not like a linux then i have no clue on how to deploy to it. :)

Amaury

Debian works like a linux system so no problem from here.

In the tuto you send me I don't understand how to know which dll are needed ?

mrjj

@Amaury
hi
You can use ldd on your exe to see which is needed.
Also there is a tool
https://github.com/probonopd/linuxdeployqt

Also the tut does list the barebone needed.
to run.

Amaury

Alright I'll have a look on that, many thanks .

Amaury

Hi again , I'm not able to run linuxdeployqt so I managed to use ldd command to find the libraries that are needed.

Can't understand anything at what should I do , in the tutorial you send in the deployment folder there only is the .exe and a file named platforms. But when I'm using the deployment oon QT creator , I get a folder with all .o/.h/.cpp files that contains my program. I certainly forgot domething to do but don't know what.

At least when running the ldd command I got :

That's all my libraries that are needed to run my app I assume but I don't know where to put this ? with all the files in my deployment folder ?

mrjj

Hi

I assume but I don't know where to put this ?

in a folder on the board. Then try to run your exe from that folder.
a deployment folder is nothing more than
a folder with Qt SO files and the exe.

Amaury

Alright thank you I made a new installation of Qt and get the 5.7 version instead of the 4.8 so I'll try that when the change is effective.

See you !

mrjj

@Amaury
ok :)
Hopefully it just runs now.

Amaury

Hope so too ! :)
