Problem setting up the development environment

[starapo7348]

I want to use the published docker container to run enigma on my PC. I want to try it for building and debugging enigma2 python 3 plugins.

I am using Openpli 9.x. (Python3)

But now I have some problems building and running the docker container.

I can't find the libdvbsi++ library. The url is not working anymore. git://git.opendreambox.org/git/obi/libdvbsi++.git

Where can I find a working copy of this library?

When I start the enigma container and enigma2 I see: eInit reached rl -1.

[gRC] Thread has finished.
[eInit] - (9) Font Render Class
[eInit] - (9) gLCD
[eInit] - (9) gSDLDC
[eInit] - (8) graphics acceleration manager
[eInit] - (5) Tuxtxt
[eInit] - (1) Background File Eraser
[eInit] reached rl -1

Also when I connect to the server/enigma2 with vnc I only see a black screen.
I think enigma2 is not started correctly.

It would be nice if someone could help me setting up a working development environment with the enigma2 docker image
with updated instructions to sort out this issues.

Thank you.

Hi, I am no longer maintaining this, sorry. For libdvbsi++ there must exist a new copy of the code somewhere.

When I start the enigma container and enigma2 I see: eInit reached rl -1.

This means enigma stopped. You need to debug why it stopped or try enabling verbose logging with ENIGMA_DEBUG_LVL environment variable

Hi, thank you for your reply. That is a pity that you no longer maintain it. Unfortunately, I have just found your project lately. This is great for developing and debugging e2 plugins. Great work! I have found the missing libdvbsi++ lib here: https://github.com/jack2015/libdvbsi.git

The code from https://github.com/rabinovic/enigma2.git compiles but enigma2 terminates with "[Enigma] Exit code 5!"

I found this for old openatv code.

if (exit_code == 5) /* python crash */
	{
		eDebug("[Enigma] Exit code 5!");
		bsodFatal(0);
	}

Your openatv 7 code also compiles but enigma2 stops with rl -1. -> https://github.com/technic/enigma2.git
Is debug level 5 ok for verbose logging? -> ENIGMA_DEBUG_LVL=5

I think I will try to switch to the actual OpenPLI code. -> https://github.com/OpenPLi/enigma2
They switched to python 3 with OpenPli 9.x meanwhile. Also the other code is old now > 4+ years.
I use OpenPLI 9 on my real VU+ Duo4k SE hardware box.

I have some compile issues but maybe could solve them. The ./configure option --with-gstversion=1.0 isn't present anymore. I don't know if I need it to run enigma.

Another compile error in enigma2 /openpli

Can I exchange the configure.ac file to change the CXXFLAGS= to -Wno-error so the warnings are not treated as errors?
And then continue building the docker container? It's hard to debug building a docker container.

I think it's easier let's say building enigma in an virtual machine (I don't want to mess with my main home linux box :) ).
When it all works I can convert it to a docker container later.

It would be nice if you could give me a few more tips on how to fix the errors, if you like.

Later I will publish the reworked and upgraded environment for all.

Thank you.

Yes doing in virtual machine is also a good option. Disable some warnings as errors is also ok. I also adapted my patches to openatv python3 enigma https://github.com/technic/e2xvfb/tree/atv-py3. It is still old though.

This is where I rebased my patches on openatv engima 3 years ago : https://github.com/technic/enigma2-atv/commits/master/
