Environment:
- MacBook Pro (Retina, 15-inch, Mid 2014)
- OSX Yosemite (10.10.4)
- Xcode 6.4
- Android Studio 1.3 RC 1 (141.2071668)
My intent is to compile V8 as a shared library so I can include it in my new
project as a standalone Javascript engine.
These are the steps I followed starting July 16, 2015 in order to accomplish
that task:
1) Used SourceTree to clone depot_tools into ~/Projects/depot_tools
2) Started Terminal, then:
export PATH=~/Projects/depot_tools:$PATH
cd Projects
fetch v8 (took about 15 min.)
3) As suggested in https://code.google.com/p/v8-wiki/wiki/D8OnAndroid
<https://code.google.com/p/v8-wiki/wiki/D8OnAndroid> , opened
~/Projects/.gclient and added:
target_os = [‘android’]
And then, on Terminal:
cd v8
gclient sync —nohooks (15:20 hrs - very slow connection)
4) Terminal again, then:
make android_arm -j16 library=shared
The process aborts with the following errors:
make[1]: *** No rule to make target ‘android_arm.optdebug’. Stop.
/bin/sh:
~/Projects/v8/third_party/android_tools/ndk//toolchains/arm-linux-androideabi-4.9/prebuilt/mac-x86_64/bin/*-gcc:
No such file or directory
make[1]: *** [out/Makefile.android_arm.debug] Error 1
make[1]: *** [out/Makefile.android_arm.release] Error 1
No idea what is “optdebug”, so I didn’t pursue any further. The missing folder,
however, was really missing. There was no prebuilt/mac-x86_64/, just one
prebuilt/linux-x86_64/. Renamed the latter to the former, and then tried again.
The new error message is:
/bin/sh:
~/Projects/v8/third_party/android_tools/ndk//toolchains/arm-linux-androideabi-4.9/prebuilt/mac-x86_64/bin/arm-linux-androideabi-gcc:
cannot execute binary file
Renamed directories to what they were before (that is, prebuilt/mac-x86_64/ ->
prebuilt/linux-x86_64 ).
Checked my Android Studio NDK folder in ~/Library/Android/sdk/ndk-bundle, found
folder prebuilt/darwin-x86_64. Copied it to V8’s /prebuilt folder, renamed it
to mac-x86-64. Tried again.
The compile step failed with these errors:

At this point, I don’t know what else to do.
Can you please tell me what am I doing wrong, and how to fix it? Being able to
include V8 as a standalone Javascript engine is vital for my project, so any
help will be greatly appreciated. Thanks in advance!
