Hola Roberto.

Sorry for the silence. Holiday break.

Can you post the errors you get?

Hola Roberto,

I managed to compile just today using Fredrik's guide but tweaking some of the flags for the raspi2.

here the summary:
-march=armv7-a
-mtune=cortex-a7
mfpu=neon-vfpv4

so the whole thing looks like this for me:
CC="gcc" CXX="g++" cmake -L -DCMAKE_BUILD_TYPE="Release" -DBUILD_TESTING=OFF -DSSE=OFF -DSSE2=OFF -DSUPERNOVA=OFF -DNOVA_SIMD=ON -DNATIVE=OFF -DSC_ED=OFF -DSC_WII=OFF -DSC_IDE=OFF -DSC_EL=OFF -DCMAKE_C_FLAGS="-march=armv7-a -mtune=cortex-a7 -mfloat-abi=hard -mfpu=neon-vfpv4" -DCMAKE_CXX_FLAGS="-march=armv7-a -mtune=cortex-a7 -mfloat-abi=hard -mfpu=neon-vfpv4" ..

I did want QT because i like to ssh and see the server windows and meter so I had to apt-get install: libqt4-dev libqtwebkit-dev

I tested and it is making the windows i want and i am able to boot the server and make sound. I haven't tested a lot, and still have to try out an external usb soundcard, but i don't see why it wouldn't work. Anyway i hope this might help you or anyone with the Raspi2...

gcc version: 4.7.2
using the ccrma-satellite image (based on wheezy)

Hi!
Please keep us posted on this. Several of us are interested in SC on ARM single board computers.

Cheers,
Ivan

Hi Brian,

Thanks a lot for your message - I'd seen an old post from you on the list and I was wondering if and how you made SC run. Perhaps I should give Arch a try, but I'm a bit weary of the time it'll take to set the rest of the environment up for this particular project I'm working on.

I am still curious if it works on Jessie, which I believe it should. I'm pretty sure there's a supercolliderist or two out there who 's made that happen on the RPi2…
Hope they see this and chime in as well. It would be nice to have an update to Fredrik's guide.

Best,
Stelios

Hi Stelios,

I did briefly have SC 3.7 working on the Raspberry Pi 2, but didn't fool around with it much... need to get back to that soon. I believe I had some luck with David Runge's package for Arch Linux (https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=supercollider-git).

It's very possible that I had a different kernel or GCC version at the time. I do remember having troubles when using Raspbian; with Arch it was easier to find more up-to-date packages.

The flags in David's package look very slightly different (neon instead of neon-vfpv4). I have no idea why that would make a difference, but you could give it a try.
    -DCMAKE_C_FLAGS="-march=armv7-a -mtune=cortex-a8 -mfloat-abi=hard -mfpu=neon" \
    -DCMAKE_CXX_FLAGS="-march=armv7-a -mtune=cortex-a8 -mfloat-abi=hard -mfpu=neon"
One other thing worth mentioning is that Sonic Pi comes with Raspbian Jessie (probably not Jessie Lite) - I think it uses scsynth, and would be surprised if it doesn't work on the Pi 2.

Good luck,
Brian
