What I realy need to build my own GUI Prgramm

[Joerg-SH]

Hello community,

after I make some experience with different images of Linux I want to do the next step.

I think there a a lot of ways of programming a application.

I just want a simple graphic user interface, gpio and other hardware programming  and not to much overhead.

My preferred language is C. My Hardware is a Sabrelite.

I have made experience with Cortex M3/M4 programming, so it is not easy to get the right way on this new land :smileyhappy:

Be free and outer what you think.

Hi Joerg,

I am not a programmer but I believe for scalability, you should use QT. Search on the community about ways to install QT4/5. In case you want an image with QT installed, try Yocto,

Hello Leo,

I have tried Yocto on the Board. It is nice, but I didn't find a working How To to set up the Host PC.

This one Building QT for i.MX6 looks good and it worked for me till I should set the Path:

$ export PATH=$PATH:/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/

I don´t find where to download that.

Do a LTIB build (try the minimal profile) with latest BSP (400). I have it on my PATH

b42214@vfae-server:~/fsl/BSP/src/linux/L3.0.35_4.0.0_130424/ltib$ ./ltib -m shell

Entering ltib shell mode, type 'exit' to quit

LTIB> echo $PATH

/home/b42214/fsl/BSP/src/linux/L3.0.35_4.0.0_130424/ltib/bin:/opt/freescale/ltib/usr/spoof:/home/b42214/fsl/BSP/src/linux/L3.0.35_4.0.0_130424/ltib/bin:/opt/freescale/ltib/usr/bin:/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/X11R6/bin

LTIB>

I'm  not sure to do that. I read now for a while on the ltip.org side. There is a lot of things I have to understand and to do before I could do that.  Or there is a How To for i.mx6 that I don't find on search the freescale forum?

regards

[LeonardoSandova · Accepted solution]

1. Download latest BSP (for to the main MX6 page on freescale.com)

2. Follow the User Guide. Basically you install LTIB and do a build

3. Follow the QT page you sent me.

4. Flash the resulting image into a SD.

Hello Leo,

I still struggle on building Ltip.

For the first errors I find a solution on google but for this I don't find anything.

Which profile are you trying to compile? try the minimal profile first (to select this, just type ./ltib -m selectype) or deselect the failed pkg (./ltib -m config). In both cases, run ./ltib again.

joerg@joergwenglish:~/ltib$ ./ltib -m selectype

Installing host support packages.

This only needs to be done once per host, but may take up to
an hour to complete ...

If an error occurs, a log file with the full output may be found in:
/home/joerg/ltib/host_config.log

If you would like to see the log messages as the host packages are built and
installed:

   * Open another terminal in the same directory
   * Run the command: tail -f host_config.log
   * When you're done with the tail, use CTRL+C to exit

Exiting on error or interrupt
Please see >> /home/joerg/ltib/host_config.log for details

Both ends with the same result.   can find spec file wget-ssl

Joerg

[LeonardoSandova]

have you installed all needed HOST packages for ltib?

Leo

[Joerg-SH]

My mistake, I used the ltip from ltip.org

I have to use that  one from BSP Package.

Thank You Leo for help

Now I think I have done  everything right but it fails again...

What Linux OS are you using?

ltib.org, not ltip.org :smileyhappy:

Hi,

Not sure how to solve your issue. One thing you can try, is to download prebuild images, then mount the rootfs.ext2 on your host, and use that rootfs when compiling QT. This way you do not need to deal with compilation issues.

Leo

that helps, see last reply
