I have setup a build environment for OpenPLI 3.0. After some initial problems it builds.

Now I would like to make a small change to openpli/enigma2/lib/dvb/demux.cpp

How and where do I make that local change in my build environment?

I'm a total newbie building using bitbake so please forgive me if the question is stupid. I can take that :-) as long as you give me a pointer in the right direction.

use the -b option to bitbake, and point to the enigma2.bb file in your e2 sourcetree

bitbake -f -c compile -b <path to e2>/enigma2.bb

and find the e2 binary in <path_to_e2>/build/enigma2-<version>/main

Thanks - Worked like a charm as did my patch... Will update my post on the "[EN] Enduser support" forum with my findings.

also you can use "diff -u" for a file or "diff -Naur" for a folder and add the patch to bb file as SRC_URI

If id like to do change to demux.cpp do I have to compile whole image or can I just use some hexeditor to do change?

I just want to change

result = 20; // 512MB systems: Use 4MB IO buffers (et9x00, vuultimo, ...)

to

result = 40; // 512MB systems: Use 4MB IO buffers (et9x00, vuultimo, ...)

As i do have issues with it and I´d like to test if it will fix my problems.
Using Vu Solo2 which has 1024MB memory.

You only have to compile enigma2... See the instructions from pieterg above.

It probably won't. The buffer size is NOT your problem, otherwise you'd see more than a single overun event.

thanks MiLo, ill keep looking other solutions.
