Prerequisites - Android

You need to:

• have the Android NDK:

  • http://developer.android.com/tools/sdk/ndk/index.html
  • use the r5c version

• have the NSPR headers installed under /usr/include/nspr:

  • apt-get install libnspr4-dev, or
  • download from https://ftp.mozilla.org/pub/mozilla.org/nspr/releases/

• export these vars:

  • NDKPATH = path to the NDK folder
  • ADB_PATH = path to the adb binary

• have a running B2G emulator/device with the ports 20700 and 20701 forwarded:

  • adb forward tcp:20700 tcp:20700
  • adb forward tcp:20701 tcp:20701

• install busybox on the device:

  • ./setup-tools.sh

• have the toolchain:

  • source bootstrap.sh

Building, running

Just ./run.sh.

Including this in B2G

Once you have the prerequisites and export the environment variables, just clone this repo inside $B2G_REPO/system/. Build and flash B2G as usual. You will be able to run the agent using sutagent. It will be in the $PATH.

You do need to set the LD path for this to work:

export LD_LIBRARY_PATH=/vendor/lib:/system/lib:/system/b2g

Start the agent on boot

Insert this after the exports in $B2G_REPO/gonk-misc/b2g.sh:

export NSPR_LOG_MODULES="NegatusLOG:5, timestamp"
sutagent &

NSPR Logging

Before running the agent (not necessary if you use run.sh):

export NSPR_LOG_MODULES="NegatusLOG:5, timestamp"

Data will be logged to $TESTROOT/Negatus.log.

Prerequisites - Desktop Linux

The linux build requires the nspr libraries and headers. On Ubuntu, you can do

sudo apt-get install g++ libnspr4-dev

Build with:

make -f Makefile.linux

Invoke with:

./agent

Prerequisites - Mac OS X

You need to have the latest version of Xcode (available from the App Store) and the command line developer tools packages installed. You will have to build your own nspr Mac installation, available at https://ftp.mozilla.org/pub/mozilla.org/nspr/releases/.

The default nspr build installs nspr to /usr/local; the Mac Makefile assumes that you have done that. To build Negatus, do:

make -f Makefile.macosx

Invoke with:

./agent
