How to update V8 locally? #127

Closed facekapow closed 8 years ago

facekapow commented 8 years ago

I tried following docs/v8_update.txt, but it failed at make x64.release i18nsupport=off with:

make: *** No rule to make target `third_party/icu/icu.gypi', needed by `out/Makefile.x64.release'.  Stop.

I'm guessing that maybe it's outdated? How do I update V8 (I'm trying update to V8 5.4.245 just to try out async/await)? Do I have to use gclient sync?

Also, how do I update the list of source files in deps/SConscript? Manually?

@facekapow async/await should already be in the current v8 behind the flag --harmony-async-await.

Re V8 update: I'm using a separate clean copy of v8 (checkout <tag>) and building it according to https://github.com/v8/v8/wiki/Building%20with%20Gyp. Then I copy generated files into runtime.js tree. Yeah, pretty much updating deps/SConscript manually by searching and filtering all the *.cc files. Or by just compiling/linking and adding undefined references.

Ahh... ok. I was assuming that the flag was --harmony_async_await (since it's always underscore separated in node --v8-options), sorry. Also useful information on how to update it in the future 👍 .
