Just to say two things:
1. Brilliant work on trying to get this working. It's potentially of
massive benefit to us all, so thanks for pursuing it.
2. Was the failure you hit during compiling the code, or on doing a DCP
encode?

Hi Carl,
I don't know how to force 1 core only...
By the way, I'm trying to build again without network connected and it
seems to work better. I only get warnings about "swp{b} use is
deprecated for ARMv6 and ARMv7".
Yet another idea: we will not use RPi2 to encode DCPs as a master
computing node, only as an encoding server. Would it be possible to
modify compilation scripts to process the relevant source files only?
Thanks for your help,
Fred

Hi Fred,
Maybe there's a bug with DCP-o-matic on ARM... can you try with 1
processing thread to see if the memory usage remains stable?
Regards,
Carl

Hi,
Bad news concerning build on RPi2: process always aborted with errors.
It seems that RPi2 has not enough power to handle the job.
At start, I see all 4 cores going up to 100%, then after a while,
memory gets
full starting swapping. This makes CPU activity going down
and finally
process halts showing error messages. :(
Disappointing...
Fred

Hi,
Configure finished :)
Your customized version of openjpeg is Ok.
Then I needed to add wheezy backports repo to get wxWidgets 3.0 to
finish
configure step.
Just launched build, Pi2 CPU is starting to burn with 4x100% threads ;)
Regards,
Fred

Hi Fred,
You might need to use my slightly customised version of openjpeg.
git clone git://git.carlh.net/git/openjpeg-cdist.git
