64 bit kernel - alanthebat - 10-08-2019
Hi
6.3 looking good here so far.
I'm currently running the experimental 64 bit kernel using mpd but also the Roon Bridge and it's been hassle free. I thought (in the spirit of exploration) I'd try the 64 bit version of the Roon Bridge but it failed during installation claiming it didn't find 64 bit versions of Application Support and ALSA.
I realise that the 64 bit kernel is experimental, and that moode doesn't really support Roon, but is there any way to source the missing versions?
Thanks
Alan

Hi Alan,
Might be a good question for the Roon guys. I'm not sure what "Application Support" means but ALSA is part of the kernel.

Thanks Tim
The actual error message was

Checking for Binary Compatibility [ FAILED ]
Checking for ALSA Libraries [ FAILED ]
STATUS: FAILED
I'll raise it with them.

@alanthebat
So all I know from your OP is that you have moOde 6.3 installed on something and that apparently you selected the 64-bit kernel in moOde config and (I have to guess here) rebooted. What else?
I have no Roon-anything so this is only an intellectual exercise but I just brought up moOde 6.3 on an RPi4B with the 64-bit kernel selected.
Code:
pi@moodelr:~ $ uname -a
Linux moodelr 4.19.75-v8+ #1270 SMP PREEMPT Tue Sep 24 18:59:17 BST 2019 aarch64 GNU/Linux
^^^^^^^I then downloaded the roonbridge installer for armv7hf (obscure notation, but this is correct for the RPi4B), marked it executable and invoked it:
Code:
pi@moodelr:~ $ curl -O http://download.roonlabs.com/builds/roonbridge-installer-linuxarmv7hf.sh
pi@moodelr:~ $ +x roonbridge-installer-linuxarmv7hf.sh
pi@moodelr:~ $ ./roonbridge-installer-linuxarmv7hf.sh
--------------------------------------------------------------------------------------
Welcome to the RoonBridge installer
This installer sets up RoonBridge to run on linux with the following settings:
- RoonBridge will be installed in /opt/RoonBridge
- RoonBridge's data will be stored in /var/roon/RoonBridge
- RoonBridge will be configured to run as a system service
- RoonBridge will run as root
These settings are suitable for turning a dedicated or semi-dedicated device
into an appliance that runs RoonBridge
If you want customize how RoonBridge is installed, see:

Hi Kent
Please don't burn a lot of time on this - it was really only for curiosity.
I'mm using a Pi 3B+ with an Allo DigiOne Sig. The only difference is that I downloaded and ran (or rather didn't run) the roonbridge-installer-linuxarmv8.sh which is the 64 bit version for the ARM platform. the linuxarmv7hf 32 bit version works fine.
Thanks
Alan

Ah, yes, a classic "ready-fire-aim" response from me. My bad
Sadly, Raspbian makes available only 32-bit user-land libraries:
Code:
pi@moodelr:~ $ dpkg --print-architecture
armhf <<hardware FP and 32-bit instructions
pi@moodelr:~ $ dpkg --print-foreign-architectures
pi@moodelr:~ $ <<-- null response; no other architecture availableRE: 64 bit kernel - alanthebat - 10-09-2019
Thanks Kent
I guess I'll have to wait for a future release. I'm not sure there would have been any real benefit in the 64 bit version but I was interested to try.
Thanks again.
