Unfortunately I'm also pretty confused by the build system..

You are trying to test this because of a change you're making to m-c right? If so, I think you can do:

  rm -rf gecko gaia out objdir-gecko
  BRANCH=master ./config.sh emulator
  ./build.sh

This should set you up with a gaia/gecko that track mozilla-central.

Cheers,
Andrew

Thanks for your help, Andrew !

It looks like you're hitting the error that bz ran into in
https://bugzilla.mozilla.org/show_bug.cgi?id=848133 which got fixed
around March 6th. When did you build?

yesterday night, so it seems like i should be good wrt this fix.

Did you run ./repo sync since
then?

possibly. i built the emulator using the standard gecko and
then tried to build with my custom gecko. i believe i rm'd
./out and then used a different objdir and then reran config.sh emulator
after setting up the .userconfig to point to the custom Gecko

Is it possible you built a b2g18 version of gaia with a m-c
version of gecko?

it's possible since this is all pretty new to me :) My .userconfig contains :

     B2G_DIR=${B2G_DIR:-$(cd $(dirname $0); pwd)}
     echo "B2G_DIR = ${B2G_DIR}"

     GECKO_PATH=~/src/mozilla-central
     echo "GECKO_PATH = ${GECKO_PATH}"

     export B2G_DEBUG=1

     export B2G_NOOPT=1

     export NOFTU=1

     GECKO_OBJDIR=${GECKO_PATH}/objdir-gonk-debug

what's the best way to make sure my gaia and gecko are in sync ?
try rm'ing out and the gecko objdir, rerun config.sh emulator and build.sh 
again ?

thanks,
ian

Hi,

i've been trying to run a mochitest in the emulator (ARM) without much luck.

i got the emulator running on Ubuntu 12.04 finally (i couldn't get it to start 
on 12.10)

i built against a local Gecko with my patch including my test applied
and the emulator also seems to start up and 'work' normally building against 
that.

i installed setuputils and ran python setup.py develop in my local Gecko's
testing/marionette/client directory.

when i try to run my mochitest from 
~/src/mozilla-central/objdir-gonk-dbg/_tests/testing/mochitest using:

python runtestsb2g.py --b2g-path ~/src/B2G --xre-path 
~/src/mozilla-central/objdir-dbg/dist/bin/xpcshell
    --emulator arm --console-level INFO --test-path 
content/base/test_CSP_inlinestyle.html

i see :

marionette.errors.JavascriptException TypeError: currentAppFrame(...) is null 
at app://system.gaiamobile.org/js/wrapper.js line 120

and then the python script exits, killing the emulator.

any ideas what might be going wrong here ? any help greatly appreciated.

thanks,
ian
