[HowTo] Moonlight-Embedded (former Limelight) using Luna Launcher

HowTo
287

Try it – that looks reasonable, but you also need to add the previously specified -DAMLOGIC directives.

288

cmake works!

next step, next obstacle :stuck_out_tongue_winking_eye:

root@osmc:/home/osmc/moonlight-embedded/build# cmake ../ -DAMLOGIC_INCLUDE_DIR=/opt/vero2/usr/include -DAMCODEC_LIBRARY="/opt/vero2/lib" -DAMADEC_LIBRARY="/opt/vero2/lib" -DAMAVUTILS_LIBRARY="/opt/vero2/lib"

No idea – but probably best to clone fresh. Make sure you build in the right directory. Vero 2 specifics should be covered now, so you can build it like you would for other platforms.

ok another milestone reached :slight_smile:

git reset --hard
git submodule update --init

fixes some make errors, now im stuck at 62% in the make process:

Thanks for taking the time. Gives the same result. Also, if i just to sudo su, or sudo -s without the echo just diconnects the ssh connection.

Im feeling i forgot some really simple yet crucial step. Need to change anything before i can add the repo?

EDIT:

Seems my ssh client was out of date or not working with the pi and osmc, switched to putty and all seems to have gone well. Although it ended with this:
‘E: There are problems and -y was used without --force-yes’

292

Make sure you have the vero2-libamcodec-dev-osmc package installed.

Try

export CFLAGS="-I/opt/vero2/usr/include"
export CXXFLAGS="${CFLAGS}"
293

how do I use these export lines?

294

Just paste them in the terminal and press enter before using cmake.

295

ok cleared the build folder and before cmake I used the export lines, same error:

Seems this is missing, but when i try to add it seems i dont have permission. How do i add this?

And will this fix this problem:

‘WARNING: The following packages cannot be authenticated!
moonlight-embedded
E: There are problems and -y was used without --force-yes’

Thanks for your help.

EDIT:

Think i got it working now, removing the -y command let me enter yess myself preventing that error. Not sure why that happens though.

297

so close at getting this done, anybody got an idea how to include the amcodec?

298

Check if this headers actually exist, we just copy the lib (as nothing else needs them). If this is the case, you can pinch the headers from the repository I mentioned before. No need to build; just copy them to /opt/vero2/usr/include so they it is under amcodec/codec.h

299

no usr folder in vero2. guess i have to create it. the libs from the package, where do i copy them from?

300

/usr is a typo, but you do have /opt/vero2/include. You can chuck the amcodec header in there and that should be enough.

301

ok found them, they were under /usr/osmc/include/amcodec.
i copied them to the PATH needed, seems it worked.
now make worked :slight_smile:

but guess it would be too easy if make install wouldn’t want to tell me something annoying:

thanks @sam_nazarko for your patience with noobs like me :wink:

303

You’re welcome. Make sure you test it first before celebrating success

304

EDIT: all fixed, just had to sudo apt-get upgrade via shh

305

Always use dist-upgrade or you could wreck your system!

306

Totally new at this, so please explain.
This was the first thing i could think of.
