Linux version is awesome.
Easy to optimize dash for RPI!
Thank You guys!

Is it possible to use somehow addressable leds?

realdashdev · January 17, 2023, 6:45am

Thanks! Not sure what you mean by that. Write a more detailed feature request to that discussion.

dmakhkamov · January 24, 2023, 1:18pm

It seems that you need a newer GLIBC. Try:
ldd --version
To see your current version.

Hi @realdashdev, do you think I can hope for a realdash linux build referencing this version of GLIBC?

realdashdev · January 25, 2023, 6:51am

As we are using a newer version of GLIB, I thing downgrading our build environments is too big of a risk to break something. Maybe you could find a way to upgrade GLIB on your distro?

dmakhkamov · January 25, 2023, 7:08am

I will try, I have reached out to the developer of openauto. Will keep you posted

dmakhkamov · January 26, 2023, 1:48pm

tried to install the latest build from my.realdash.
got this error.

The following packages have unmet dependencies:

 realdash:arm64 : Depends: libbluetooth3:arm64 (>= 4.91) but it is not installable
                  Depends: libc6:arm64 (>= 2.27) but it is not installable
                  Depends: libdbus-1-3:arm64 (>= 1.9.14) but it is not installable
                  Depends: libgl1:arm64 but it is not installable
                  Depends: libglib2.0-0:arm64 (>= 2.12.0) but it is not installable
                  Depends: libgstreamer1.0-0:arm64 (>= 1.0.0) but it is not installable

                  Depends: libvlc5:arm64 but it is not installable

all these libs are installed and are newer version. for instance, the libc6 is v 2.28

realdashdev · January 27, 2023, 10:04am

And this is on OpenAuto distro?

I’m sorry, but I really cannot help you there. Can the developers of that distro tell you why these packages are not installable?

I can try to upgrade some of the dependencies for next build, but risk is that it will force out some existing installations that do not have newer packages available.

dmakhkamov · February 3, 2023, 4:40pm

@realdashdev yes, its openautoPro. I’ll try to deal with it on my own, and keep group posted

realdashdev · February 15, 2023, 8:46am

I updated the first page instructions on how to install without dependencies. It may or may not work, but could be worth a try.

dmakhkamov · February 28, 2023, 9:14pm

Hi, I’ve checked. Uninstalled the build, and installed the v2.2.1. installation runs with no issues, but when I launch realdash nothing happens, and when I launch it through the console, typing “realdash”, it gives the same GLIBC dependency error.

realdashdev · March 2, 2023, 11:24am

I’m sorry that I have not been able to help with this. I don’t understand why install fails when requirement for GLIBC is 2.27 or newer, and you definitely have a newer version installed.

dmakhkamov · March 3, 2023, 4:46pm

maybe I am doing something wrong. But so far I have narrowed down to the following:

Small correction, install does not fail, launch does.
The distro is buster, which is based on debian 10, which has 2.27.
I have contacted the developer for the release date for the new version, and if that would be based on deb11, which has glibc 2.30+something.

in the meantime, maybe trying to launch it on that distro might help you?
If you want I can share the image you can flash on your pi. Also, my guess is that the issue should be re-creatable on any distro based on deb10.

realdashdev · March 6, 2023, 9:03am

I tried to dig little deeper. We are using Raspberry Pi:s to compile the Linux ARM versions of RealDash. Even when install package states minimum GLIB version of 2.27, the build environment uses 2.31:

ldd (Debian GLIBC 2.31-13+rpt2+rpi1+deb11u5) 2.31

This is probably why it will not start even when it installs.

As stated earlier, we cannot downgrade the build environment. Currently your only option is to update the GLIB. I think this is doable by setting update repo to Debian11, not sure though.

Can someone possibly help, I am new to Linux but wanted to give it a go.

Khadas VIM3, running ubuntu firmware from: https://dl.khadas.com/products/vim3/firmware/ubuntu/emmc/

Ran the below as listed on the 1st page,
-sudo apt install libopenal1 libvlc5 libssl1.1 espeak-ng
-sudo dpkg -i realdash-mrd_2.2.2-1_arm64.deb

Seems to have installed ok. But when I click on the application, it fails to launch/open. If I run realdash from terminal, i get the following error:
khadas@Khadas:~$ realdash realdash: /lib/aarch64-linux-gnu/libasound.so.2: no version information available (required by /lib/aarch64-linux-gnu/libsndio.so.7.0) realdash: /lib/aarch64-linux-gnu/libasound.so.2: no version information available (required by /lib/aarch64-linux-gnu/libsndio.so.7.0) 02:51:14.213 os_linux.cpp(441)(tid:0xf51a3565) : NUTS_INFO - Segmentation fault

Sounds like the same issue described by @fscker back on page 7, resolved by @smwoodward. Something about putting Mainline Kernel Section on an SD card, booting it, then copying it over to the emmc… however the link posted is dead, and I cant find any further helpful information.

dmakhkamov · March 31, 2023, 11:22pm

Hi @realdashdev,

I’ve finally killed off my RealDash running on Android (Konstakang) on RPi4, and have installed the Linux version.

However, I am facing an issue of “Failed to Update Gallery”.
Seems like some permission things, but i don’t know where to start to find out what’s causing it.

aperillat18 · May 20, 2023, 3:34pm

I am having an issue with libssl1.1 saying it cannot locate it. However real dash seems to be installed. when I run it from the apps nothing happens. when I run it from terminal I get error while loading shared libraries: libssl.so.1.1 cannot open shared object file: No such file. I followed the directions above but I assume I did something wrong or am missing something here. I am running this on Ubuntu current version raspberry pi 4. If there is a better way to run Real dash I am open to that as well, Any help would be greatly appreciated.

b0ch3n · May 21, 2023, 10:37am

I find it super impractical to rely on OS dependencies. Currently I’m working on getting RealDash to work in a Docker container and make is OS-independent. Got it running on Arch Linux on my main box in a container, but still some issues to be resolved (and also a test on RPi). I will post some of the details once I get it in shape

realdashdev · May 22, 2023, 5:53am

Using Rasbian OS will make sure that you have all dependencies installed. I don’t think you gain any performance using Ubuntu instead of Rasbian.
