[solved] why the Qt program is used libts-0.0.so.0 in mini2440?

[MhM93]

Hi
I have a question. what is the libts-0.0.so.0?
when i copy the library to mini2440 and run demo in my device it show me this error: error while loading shared libraries: libts-0.0.so.0: cannot open shared object file: No such file or directory.
but when i open my application ( that compiled with arm-linux-gcc4.4.3 and Qt version 4.6.3) it does not show me this error. i think maybe my program does not used this lib?
( when i solve this lib problem the demo touch is worked but my app touch is not worked) I guess maybe cause of this libs?

Hi,

That's the library used for touch screen handling. Depending on where you copy it on your device, it might not be found hence the error your are getting.

[MhM93]

ohom, thank you, so when my aplication run without libts error but the example run with this error. it means maybe my application can not call this touch library. is it right?
so how can i call this library in my Qt application?

[SGaist]

What example is it ?

[morkia]

It's not exactly clear that what is your problem from the description you have provided but I hope you find these info I'm providing helpful:

• you need to find out whether the device driver for your touchscreen device is installed and working properly. If it's a USB one disconnect and connect it again and then in your terminal run dmesg command and see the few last lines and check if there's any info about touch screen device available and also if it's configured and working properly i.e. no warnings or errors.

• touch screen is handled like mouse, user space applications don't see the difference. it's handled under the hood.

• if you are using X window manager then you might need xorg-xserver-input-* (replace the * with the one required for your case) packages installed.

Also try to see if you can use later versions of Qt. I've worked with mini2440 and have successfully installed Qt 5.0.0 on it. Could you tell us what operating system you are using on your ARM device? I hope it's not the default one provided with the board :)

Hi.
@SGaist the example i said ,I mean the demo in first topic i said.
@morkia this topic is my base question about mini2440. when i reinstall Linux on mini2440 and does not make static link at first ( for this error: libts-0.0.so.0 is a shared library or ...) i was running my app and the touch not worked. i tested it with the demo in mini2440 but it shows this library error. ( this is all my story :D ).
my linux version is 2.6.32.2.this is dmesg

sorry but i do not know about if I have error or not. and what is the meaning of that line i bold them.

if you are using X window manager then you might need xorg-xserver-input-* (replace the * with the one required for your case) packages installed.

i don't know X window manager.

Also try to see if you can use later versions of Qt. I've worked with mini2440 and have successfully installed Qt 5.0.0 on it. Could you tell us what operating system you are using on your ARM device? I hope it's not the default one provided with the board :)

Unfortunately, I used the basic Qt (Qt4.6.3). I don't know how to install new Qt on my board. :D

[morkia]

If you are running a Linux on your PC or Laptop then you are most certainly using the X window manager. Just search it in your favorite search engine like Google. Most modern arm processors are capable of running X window manager like Tiny X. How did you build the Linux for your board?

in your dmesg output the line input: s3c2410 TouchScreen as /devices/virtual/input/input0 shows that you have the driver loaded for your kernel. If it works outside the Qt then there's something wrong within your code just post a snippet of your code so I can see where the problem might be.

The parts that you have highlighted are related to your MTD device. Don't worry about them those are managed by your hardware automatically. If you swith off your board without properly shutting it down first, that could happen (an unsuccessful write damaged a block in your memory like a bad sector in your hard drive). Also the YAFFS2 file system scans for those blocks and then reuse them during it's garbage collection.

Also, You have marked your issue as solved. Is it really solved or you still have problems with it?

[MhM93]

Hi and thanks for reply @morkia
thanks for your describe. :)

Also, You have marked your issue as solved. Is it really solved or you still have problems with it?

my main problem not solved. but the question in this topic is solved.

If it works outside the Qt then there's something wrong within your code just post a snippet of your code so I can see where the problem might be

this is my program that i uploaded. it is a simple hello world with Qt 4.6.3:http://project-free-upload.com/sg5yrgxi2ixs

[morkia]

your program consists of a main window on which you display heloo within a QLabel there's nothing to click on! What do you expect from it?! I suggest you at least put a QButton or something that reacts to click events.

[MhM93]

at first my program has a click when it clicked show a message to say hello but the touch not worked. i think maybe my program has error. so i make a simple program to just show a simple label. but when i run it . the mouse is place the center screen and dose not change the location when i touch the display.

[morkia]

Place a button or something that accepts a click and then test your program. Don't pay attention to the cursor you see. If you don't have a window manager (which is very likely considering you are using an ancient arm device) then your cursor might not move around because there's no program to handle that for you. Remember everything is a software. It doesn't come by itself. So if you place a button or any widget that reacts to click events in your software, Does that work?

[SGaist]

@morkia Qt 4 for Embedded Linux provides it's own window manager, nothing to do with the age of the processor.

@MhM93 what parameters are you giving to your application when you launch it ?

[morkia]

@SGaist yes it does provided it's correctly compiled. Also the platform on which you run Qt applications matter too.

[MhM93]

Hi and thanks for reply @morkia @SGaist . (and Sorry cause I am so busy because changing my home and cant see this topic)
@morkia : I said that my first program is a window with a button. when i clicked the button show message. but nothing worked in my app (just display the window with button). I guessed maybe the ARM device does not support the QmessegeBox. so I changed my app to a simple hello word with a simple label. but the touch not worked. (that program with message box is worked on tiny6410)
@SGaist : I called my program like this:

cd /udisk/
./prj3 -qws

but just display my app with no touch. my last Topic

[morkia]

I could help you better if you would tell me what kind of Linux you are using and how you installed it on your board. I might tell you how to build a Linux for your board here, But first I should know if it's done correctly. All I can sense from here is an incorrectly configured installation of Linux. Tell me if you are interested.

[SGaist]

@morkia said:

If you don't have a window manager (which is very likely considering you are using an ancient arm device)

Again, this part has not much to do with the age of the device, Qt for Embedded Linux with the Qt Windowing System was already running on ARM devices more than 10 years ago.

Part of the problem is here is that just saying -qws doesn't tell Qt that you have a touch screen at hand. You need to tell it that you are using TSLib. It's described here

[morkia]

@SGaist Yes but in my personal experience It's better to use a window manager like tiny X. Also since Qt is usually compiled from source for such cases, it's difficult for new and inexperienced users to get it to work right i.e. supplying proper configurations etc.

This is the reason I'm continuously asking her to tell me how she has built the Linux for her device. If she uses X, then she won't have to worry about input device handling. It simply becomes transparent to her.

by that statement I meant the way Linux is usually built and deployed on devices like hers.

[MhM93]

@morika : Hi and thanks. I really want to know how to enable touch and understand the ARM structure.

I could help you better if you would tell me what kind of Linux you are using

but no touch again. ( ts_calibrate worked but my application touch not work)

Part of the problem is here is that just saying -qws doesn't tell Qt that you have a touch screen at hand.

I think I don't understand it !!the device demo is worked with this parameter./fluidluncher -qws -> this is worker completely even touch work.

[SGaist]

ARM is just a processor architecture, you can find yourself having the exact same problem on x86. What matters more is the distribution you use as well as the kernel.

Did you compile fluidlauncher yourself ?

[MhM93]

@SGaist : Did you compile fluidlauncher yourself ? No . this demo is in device and worked. you mean my compiler is wrong? but i compile my project as the same as some sites guide.
