whel thanx to @mitu whit out nowing it igot it to work i think.
the problem was the first stap what i dident notis.
and @mitu did say i a noder post "
The GCC version included in Raspbian Buster is stricter now and because of the all warnings being treated as errors compilation parameter, it refuses to compile libhid.
What you can do is to remove the -Wall usage by running configuring the libhid build (and probably the other libraries included), with

./configure --disable-warnings "
wel so i try that and its working.
so for so far i can thel i can turn the leds on and of using the command line (in terminal).
hope the rest is working to i gone try that now.

@MeduZaPaT nope, not got round to it yet
I got sidetracked by a new build.

@Creteloc

if there is no software from the manufacturer to change this (which i doubt for a cheap encoder like this), you might aswell give up, the microswitches you have, simply cannot physically handle what you want them to do.

however, if this is just a matter of the leds being too bright, you could just add some resistors to lower the brightness of the leds.

@Yornav No for Retroarch cores, as far as I know. Maybe for some version of advancemame, but I have not look at it. They will work if you compile the latest standard mame, but it will run very slowly on the Raspberry.

Sorted, finally found this thread which shows the exact way to wire them.

@SigmaX what OS are you running in the Pi3 ?

A little more searching and I found a great thread that describes this: https://retropie.org.uk/forum/topic/17533/how-do-i-get-these-led-arcade-buttons-to-light-up

I'm using a Pac-Drive from Ultimarc for my LED buttons. @savetheclocktowr made a controller software for some nice sequencing effects. It's not needed for permanent lighting, the Pac-Drive will do that out-of-the-box in Retropie.
