# Prerequisites
|
|
* a Linux/Mac workstation
|
|
* v8 r12178 (on Google Code) or later
|
|
* an Android emulator or device with matching USB cable
|
|
* make sure [building with GYP](http://code.google.com/p/v8-wiki/wiki/BuildingWithGYP) works
|
|
|
|
|
|
# Get the code
|
|
|
|
* Use the instructions from https://code.google.com/p/v8-wiki/wiki/UsingGit to get the code
|
|
* Once you need to add the android dependencies:
|
|
```
|
|
v8$ echo "target_os = ['android']" >> ../.gclient && gclient sync --nohooks
|
|
```
|
|
* The sync will take a while the first time as it downloads the Android NDK to v8/third\_party
|
|
* If you want to use a different NDK, you need to set the gyp variable android\_ndk\_root
|
|
|
|
|
|
# Get the Android SDK
|
|
* tested version: `r15`
|
|
* download the SDK from http://developer.android.com/sdk/index.html
|
|
* extract it
|
|
* install the "Platform tools" using the SDK manager that you can start by running `tools/android`
|
|
* now you have a `platform_tools/adb` binary which will be used later; put it in your `PATH` or remember where it is
|
|
|
|
|
|
# Set up your device
|
|
* Enable USB debugging (Gingerbread: Settings > Applications > Development > USB debugging; Ice Cream Sandwich: Settings > Developer Options > USB debugging)
|
|
* connect your device to your workstation
|
|
* make sure `adb devices` shows it; you may have to edit `udev` rules to give yourself proper permissions
|
|
* run `adb shell` to get an ssh-like shell on the device. In that shell, do:
|
|
```
|
|
cd /data/local/tmp
|
|
mkdir v8
|
|
cd v8
|
|
```
|
|
|
|
|
|
# Push stuff onto the device
|
|
* make sure your device is connected
|
|
* from your workstation's shell:
|
|
```
|
|
adb push /file/you/want/to/push /data/local/tmp/v8/
|
|
```
|
|
|
|
|
|
# Compile V8 for Android
|
|
Currently two architectures (`android_arm` and `android_ia32`) are supported, each in `debug` or `release` mode. The following steps work equally well for both ARM and ia32, on either the emulator or real devices.
|
|
* compile:
|
|
```
|
|
make android_arm.release -j16
|
|
```
|
|
* push the resulting binary to the device:
|
|
```
|
|
adb push out/android_arm.release/d8 /data/local/tmp/v8/d8
|
|
```
|
|
* the most comfortable way to run it is from your workstation's shell as a one-off command (rather than starting an interactive shell session on the device), that way you can use pipes or whatever to process the output as necessary:
|
|
```
|
|
adb shell /data/local/tmp/v8/d8 <parameters>
|
|
```
|
|
* warning: when you cancel such an "adb shell whatever" command using Ctrl+C, the process on the phone will sometimes keep running.
|
|
* Alternatively, use the `.check` suffix to automatically push test binaries and test cases onto the device and run them.
|
|
```
|
|
make android_arm.release.check
|
|
```
|
|
|
|
|
|
# Profile
|
|
* compile a binary, push it to the device, keep a copy of it on the host
|
|
```
|
|
make android_arm.release -j16
|
|
adb push out/android_arm.release/d8 /data/local/tmp/v8/d8-version.under.test
|
|
cp out/android_arm.release/d8 ./d8-version.under.test
|
|
```
|
|
* get a profiling log and copy it to the host:
|
|
```
|
|
adb shell /data/local/tmp/v8/d8-version.under.test benchmark.js --prof
|
|
adb pull /data/local/tmp/v8/v8.log ./
|
|
```
|
|
* open `v8.log` in your favorite editor and edit the first line to match the full path of the `d8-version.under.test` binary on your workstation (instead of the `/data/local/tmp/v8/` path it had on the device)
|
|
* run the tick processor with the host's `d8` and an appropriate `nm` binary:
|
|
```
|
|
cp out/ia32.release/d8 ./d8 # only required once
|
|
tools/linux-tick-processor --nm=$ANDROID_NDK_ROOT/toolchain/bin/arm-linux-androideabi-nm
|
|
```
|
