How To Use Qt On Pc To Make Application For An Embedded Device ?

Hi everyone!

Having read about the latest LibreOffice version, I felt tempted to try it out. I uninstalled the default version on my Ubuntu machine and downloaded the .deb from the LibreOffice site and installed it. The new office has since worked without any trouble.

A few days later I decided to dump Unity and go back to Gnome. So I installed Ubuntu-Gnome-Desktop.

It was then that I noticed two versions of LibreOffice on the application dash (I think, because there are two sets of icons for each office application- see the attached screenshot).

Did Gnome install its own version of LibreOffice with it? Does it really have one? I don't know.

Whichever icon I use to launch the app, the office however always brings up the latest version. So, there's no problem in terms of application errors. As I thought there's no need to have an extra version of an app and eat up my space, I tried to uninstall through Aptitude, but it doesn't 'remove' LibreOffice.

Any advice, please! Thanks in advance.

Hi,

I am currently working on a Embedded system (linux 2.6.24) and need to set a ftp daemon on it.
I have the busybox v1.4.2 on it but it don't have ftpd on it.
After searching on internet i find tons of way to install a ftp daemon on normal linux computer but no explanation on how to do it on an Embedded devive.
I am not the one who installed the distro and busybox, i have no knowledge on how to make this. I have no sudo/apt-get/make command on my system.

Hi folks,

after googling for a couple of days, I get the feeling, this is a common problem. But the usual fix doesn't seem to work for me.

I am trying to install Linux on a separate partition of my Acer Aspire V5-573G. I used the Lili USB Creator to make a bootable USB drive with Ubuntu 12.04 on it.

when I reach the installation menu, it doesn't matter what I choose (start live, install..), my notebook will always freeze on a black screen.

I figured out how to add 'nomodeset' to the grub line. This does bring me one step further (the Ubuntu start screen) but then I get this message:

Code:

ubuntu@ubuntu:^^$ [   20.267422] mei 0000:00:16.0: init hw failure. 
[   20.267558] mei 0000:00:16.0: initialization failed.

After pressing enter I get a command line. From here I don't know what to do.

I've tried other distros (Lubuntu, Linux Mint), but then even 'nomodeset' didn't make a difference. I have also tried to add 'acpi=off' to the grub line after 'nomodeset', but again only black, even with Ubuntu.

Any suggestion or help will be greatly appreciated!

I was wanting to know if there is a Linux USB creator that includes the Tails distribution that will work on a Macbook Air with OS X.

Hi all!! Im new in this forum and also new at linux !!

I am installing an application that includes automatically the instalation of CentOS 6.3.

The server that hosts this application and OS had a power outage and then when i turn on the server again i get the error that you can see in this pictu http://postimg.org/image/7opm0xzel/

I have 2 disks in the system, 1 for the application and SO and other to store call recordings (thats what the application do, record calls!).

If I re-install the system it has no problem!! But i dont want to re-install the system every time i have a power outage because i lost too much and important information.

I have installed this application in other server and had no problem with power outage. In this server the diference is that it originally had raid and i "remove it" frome the BIOS. Maybe here is the problem??

Anyone can help me?? Remember im really new in linux !!

Hi,
I made some little applications with qt creator and i wanted to run them on an embedded linux board (linux 2.6.24). To transfer the files i use a SD card. If i move the applications to "/bin" after having mounted the SD card and then "chmod a+x" them then i have no problem running them.
But if i mount the SD card and try to run the applications directly in the folder where i mount it i have an error : "Permission denied". Also when using the command "ls" i notice that if i keep the files in the mounting folder and try to "chmod a+x" them, the modification don't happen. They stay "greyed" and don't go "green". (I don't know if this color code is a standart for linux terminal but maybe this could help you understand the problem).
When mounting the SD card i use the command :
Code:

mount -t vfat /dev/mmcblk0p1 /mnt/SD

So the files are located in /mnt/SD.

Am i missing something or is it not possible to run something like that ?

EDIT :
I tried "mount -t vfat -o umask=0000 /dev/mmcblk0p1 /mnt/SD" to chnage how i am mounting the SD card.

Still "Permission Denied".

With "ls -l" i can see that the permissions are staying :
-rw-rw-rw-

Even if i try something like "chmod 777".

It seems to be a problem related to the fact that the sd card is formated as fat32 but it must stay like that.

I recently installed google earth on Ubuntu 14.04 64 bit and right after installation finished , I lost much of power of wifi 3G modem installed, beeing unable to watch video on any browser without interruptions,unable to do video call on skype and I need to wait for page to be loaded in addition updating lasts ten times longer . Uninstallation of google earth did not solved the problem of lost power of wifi modem the "Conection Information" show speed: 65Mb/s

Thanks much,

SYSLINUX: No DEFAULT or UI configuration directive found!

Googled this error and found a solution to rename folders.

Did that.

Rebooted and face this error now.

Counld not find kernel image /isolinux/isolinux.cfg.




Can someome please help me on this. Will be very thankful.

Hello everyone.
The sound isn't working on my debian live usb.
I've installed pavucontrol hoping that this would turn on the sound somehow. But it hasn't.

The program is showing RS880 HDMI audio [Radeon HD 4200] as my output device.
The play back bar moves when I play video on youtube but there is no sound.
On the configuration tab, I've tried all the options under 'built-in audio' - but none of these seem to work.


aplay -l

Code:

 
**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: ALC892 Analog [ALC892 Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 0: SB [HDA ATI SB], device 1: ALC892 Digital [ALC892 Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

Don't know why there are 3 playback devices...

lspci | grep -i audio

Code:

00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) (rev 40)
01:05.1 Audio device: Advanced Micro Devices [AMD] nee ATI RS880 HDMI Audio [Radeon HD 4200 Series]

Not sure why there appears to be two sound cards...

On a Ubuntu site about a similar problem with the same sound card, they suggest creating /etc/asound.conf and adding code to it http://ubuntuforums.org/showthread.php?t=1647400
However, at this point, I'm a bit lost.
Can someone help please?

Hi Everybody.....
I'm new to this site and new to Linux ( Ubuntu 12.04) generally. I am an old goat mechanical engineer with years of electronic instrumentation design experience. I am connecting several of my old HP digital oscilloscopes and logic analyzers to a Ubuntu box via GPIB (ieee 488) interface. I have the interface working well using the open source ( Sourceforge) "Linux-GPIB" kernel module. I can remotely control the instruments using "Linux-GPIB"'s "ibterm" terminal utility. However "ibterm" doesn't provide a means to do a scope screen dump to a file. A guy on EEBLOG published a short C language 30 line source code to perfome this function. Unfortunately it isn't a package with makefile.am, makefile .in, configure etc which I understand I could compile using the typical ./config, make, checkinstall procedure. It is just the c source code text. Soooo.....do I use gcc directly? If so, how do I run gcc in a manner to be able to uninstall all the various files it will make? Or ?? What is the procedure for automake in this situation ? Or....? I'm kind of lost. Your suggestions would be helpful.
Cheers.
