Hi,
Currently, I'm only trying to compile... We'll see later for encoding ;)

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

To give some news about dependencies:
- libcxml => Ok, I had to recompile from your source code
- libxml => Ok
- libcurl => Ok
- all boost stuff => Ok after git pull
- libavformat => Ok
- libavfilter => Ok
- libavcodec => Ok
- libavutil => Ok
- libswscale => Ok
- libswresample => Ok after adding deb-multimedia repository to solve all relative
dependencies
- libpostproc => Ok
- libdcp => not found
I'm trying to recompile libdcp to install it, but at the moment, I get an error with
libopenjpeg not found in pkg-config search path.
I've already installed libopenjpeg-dev latest package available in raspbian repo.
Regards,
Fred

Hi Fred,
Cool, I'll try a build here on a V1 Pi and see if it's possible.

Boost is now Ok, I'm resolving the following
dependencies one by one ;)
Keep in touch,

Hi,
Same result, configure still halted on Boost library. See config.log... :(
Different bug, now fixed. Please git pull and re-try.
Rechecking dependencies, I don't find libdcp
dev package, can you give me some details?
You can get a tarball from http://carlh.net/software/libdcp
or
git clone git://git.carlh.net/git/libdcp.git

Carl

Hi Fred,
Please checkout dcpomatic from git (if you haven't already) with
git clone git://git.carlh.net/git/dcpomatic.git
then configure it with
./waf configure --target-arm
and whatever other options you are using. I just added the
--target-arm option to fix the problem you are seeing.
Thanks!
Carl
