Compiling Chromium Browser for PI (Done)

[moonman]

Package now is in the official repository:
$this->bbcode_second_pass_code('', 'pacman -Sy chromium')
______________________________________________________________________________________________
Grab the package here: $this->bbcode_second_pass_code('', 'pacman -U http://dl.dropboxusercontent.com/u/15043728/ArchLinuxArm/RaspberryPI/chromium/chromium-27.0.1453.93-3-armv6h.pkg.tar.xz')

I'm trying to compile chromium browser for the pi. I'll document things as I go here for future reference.

So far it's been over 14 hours and it's still compiling (with distcc).

-- does not build with ffmpeg (have to use "use_system_ffmpeg") files that may need to be looked at:
third_party/ffmpeg/ffmpeg.gyp
third_party/ffmpeg/chromium/scripts/build_ffmpeg.sh

In ffmpeg.gyp armv7+thumb values are hardcoded (who was coding it?!)
$this->bbcode_second_pass_code('', '['target_arch == "arm"', {

Welcome to our world. Thanks for looking into it.

No problem. I already tried compiling it for armv5 and failed It did compile but wouldn't run. armv6 should be easier. (I hope)

I think there's something wrong with my Pi. It's using 700MB of swap and there's >300MB of ram free. This is 5th time I checked today and swap usage was going up and down, but ram always stayed @ 300 free.

[moonman]

It seems it's linking the final binary (chrome). Hopefully it means it (almost) successfully finished. It's been >5 hours since it started linking and over 24hours since I started compiling. swap is at 1GB usage I'm pushiing the poor thing to its max.

Finally compiled and it works. It's was linking for several days!
