Howto compile Node android arm shared with NDK r17 canary and libc++?

[aschrijver]

I am trying to compile NodeJS as native library for Android (arm) on Ubuntu 16.04 (4.4.0-59-generic) with the latest NDK continuous build

I am using canary NDK because of earlier node-matchers.h error 'nearbyint' is not a member of 'std' with stable r15 ndk and this github issue: android/ndk#82 (comment)

Procedure:

• git clone --depth=2 -b v8.x https://github.com/nodejs/node.git
• Edit android-configure: add --force to make_toolchain, add --without-intl --shared to configure
• ./android-configure /home/arnold/Android/android-ndk-r17-canary arm
• LDFLAGS=-shared make

And the resulting output was:

In file included from ../deps/v8/src/compiler/ast-graph-builder.cc:16:0:
../deps/v8/src/compiler/node-matchers.h: In member function 'bool v8::internal::compiler::FloatMatcher<T, kOpcode>::IsInteger() const':

I thought this was fixed in latest NDK. Any ideas?

@DanAlbert was kind enough to point out I am still using gnustl and not 'libc++ which leads to this error.

The only issue is, I do not know how to configure libc++. There is no Application.mk and I tried adding --stl=libc++ to the toolchain cmd in android-configure but that does not do it. How can I pass this setting?

FYI:

I've tried many different ways to get NodeJS running on Android and spent yesterday all-day compiling without success.
I am investigating some viable-seeming approaches to use NodeJS in an android project. I have documented my findings on stackoverflow - Viable options to running NodeJS on Android (Aug 2017).

Is this a duplicate of #14783? If so we should probably close it so any discussion happens in one place.

[DanAlbert]

Looks like it.

[gibfahn]

I'll close. @aschrijver I'm happy to reopen this if you think it should be reopened, let me know.

No problem. I will transfer my findings there and add a descriptive title :)
