when do you update this android-jsc to support es6?

builds-nightly.webkit.org returns 'permanently moved' response. With response save with WebKit-r174650.tar.bz2 name, so it's failed to extract.

Replacing http to https fixes the issue.

why not support armeabi? React Native used this, but not support armeabi, i guess depend on this.

How to support armeabi?

React Native The current license is MIT, but it depends on android-jsc indeed BSD+PATENTS, no one cares about this?

I'm probably doing something weird, but when I run buck build :android-jsc I get the following errors

BUILD FAILED: Couldn't get dependency '//jsc:jscoffsetextractor#android-x86,static' of target '//jsc:LLIntAssembly.android-x86.h':
Unrecognized flavor in target //jsc:jscoffsetextractor#android-x86,static while parsing //jsc/BUCK.

Any ideas? Thanks :)

how can i exclude x86 .so by edit ndk gradle or any config when i use React Native for Android,thks

becase , the .so [4M] is too large for us，and in china machine base on x86 is very rare,so we decide to cut down the x86 support, thanks for tell me how to deal with this project

I want to create a build with symbols for debugging. any help?

Recently encountered the jsc issue, which big guy can help solve it, thanks!

in abjectively case , another maven GAV also has Nullable which the package is also javax.annotation.
even i can exclude an dependence a GAV ,bug i can't exclude all the files in an exist package,opps!

I cloned the repo and ran ./fetch_sources.sh and got the following error when extracting JSC:

According to this page, WebKit nightlies are no longer supported, so seems this script needs to be updated. They have a build archive here but it doesn't seem to have source code, just compiled code.

Can someone link me an example project in use since I am using Adrnoid Studio and when link my .so by cmake this shows the following message "Application stopped work"

Tried this on my macOS machine, which failed.

Turns out it was this line:

Baggerss-MBP:android-jsc Baggers$ tar -jxf WebKit-r174650.tar.bz2 -C jsc --strip 2 WebKit-r174650/Source/JavaScriptCore WebKit-r174650/Source/WTF

tar: WebKit-r174650/Source/JavaScriptCore: Not found in archive

Also tried on a fresh ubuntu install in a vm. Fails on same line

baggers@bbuntu:~/Code/android-jsc$ tar -jxf WebKit-r174650.tar.bz2 -C jsc --strip 2 WebKit-r174650/Source/JavaScriptCore WebKit-r174650/Source/WTF
bzip2: (stdin) is not a bzip2 file.
tar: Child returned status 2

Any advice would be very welcome

We should take advantage of the JIT if we can. Opening this issue so we don't forget about it. cc @kmagiera @astreet

It looks like JSC Android hasn't been updated since 2015. Are there any plans to update android-jsc?

There are bugs in the Android version of JSC which result in different behavior compared to iOS. A more modern version of JSC on Android would help minimize differences.

I've updated .buckconfig to use ndk_version = r15c NDK is installed and environment variables are setup.

export ANDROID_HOME="$HOME/Library/Android/sdk"
export ANDROID_NDK_REPOSITORY="$HOME/code/android_ndk/android-ndk-r15c"
export ANDROID_SDK="$ANDROID_HOME"

It'd be nice to at least have Travis CI enabled to verify the code builds.
