Compile V8 for Android

[Yann Bonnetain]

Hi 

I am been starting from here to fetch and build V8

Both on Mac and Ubuntu I have the following error when I try to make the target android_arm.release

gyp: Error importing pymod_do_mainmodule (has_valgrind): No module named has_valgrind

However, has_valgrind exists in tools/

Is there a missing configuration I am not aware of ?

Some help would be great :)

Works for me. Which version of V8 do yo have checked out? What does "which gyp" say? If you have /usr/bin/gyp or something installed by your distro, that could interfere; make sure depot_tools is the first thing in your $PATH.

(Also, has_valgrind.py should exist in gypfiles/, I assume "tools/" was just a typo: https://chromium.googlesource.com/v8/v8/+/master/gypfiles/has_valgrind.py)

Hi Jakob and thanks for your help

I have branched of V8 master

which gyp

Does not print anything 

sudo find / -name 'gyp'

~/depot_tools/v8/build/android/gyp

~/depot_tools/v8/tools/gyp

~/depot_tools/v8/tools/gyp/gyp

~/depot_tools/v8/tools/gyp/pylib/gyp

which seems to show that no other gyp is present

depot_tools is in first position in $PATH and points to the actual depot_tools folder

v8/gypfiles/has_valgrind.py is there (sorry for the confusion)

Is there a specific branch for Android?

I cannot figure out what I have missing (the error is the same on a VM running latest Ubuntu and Mac OS)

[Jakob Kummerow]

I'm not sure what else to try, sorry. I haven't seen this error before and can't reproduce it.

That doesn't mean anything; everything is branched off master. Maybe try updating? The gyp files moved recently (from build/ to gypfiles/), maybe there were a few commits where not everything was working correctly.

No, every version should build for Android.

Turns out there was a small update to Makefile.android missing. The build still worked on machines that had an old build/has_valgrind.pyc file lying around from before the files moved...

After https://codereview.chromium.org/2003513002/ it should work again on fresh checkouts.

Oh well spotted !

Again thank you so much for your help.
