libnode.so for 32 bit is missing

[dominictarr]

okay it looks like I got it installed, it says it built successfully, but when I tried to run it on my phone I got this error:

Error:error: '../../../../src/main/jniLibs/armeabi-v7a/libnode.so', needed by '../../../../build/intermediates/cmake/debug/obj/armeabi-v7a/libnative-lib.so', missing and no known rule to make it

I'm trying to figure out where libnode.so comes from?
okay, a bit of searching led me here: nodejs/node#14158

gonna check that out...

btw, I changed line 14 of app/build.gradle to

abiFilters 'armeabi-v7a', 'arm64-v8a'

[dominictarr]

do I have to build libnode.so or can I download it from somewhere?

[dominictarr]

hmm, so node has an android-configure script, with this comment at the top:

# In order to cross-compile node for Android using NDK, run:
#   source android-configure <path_to_ndk> [arch]
#
# By running android-configure with source, will allow environment variables to
# be persistent in current session. This is useful for installing native node
# modules with npm. Also, don't forget to set the arch in npm config using
# 'npm config set arch=<arch>'

so this seemed to work:

./android-configure ~/android-sdk/ndk-bundle/ arm --shared

remember to include "--shared" so that it becomes a shared object

It looks like 32-bit is not supported currently.

It says only ARM64

@dominictarr did it compile? Would be super helpful if you could share the shared lib with me so I can package this up so we dont need android studio. Here is how I compiled in Termux otherwise

Building Node.js as a shared library in Termux

Install deps

pkg install git python2 #and the compilers

Clone the node repo

git clone git://github.com/nodejs/node.git
cd node
git checkout v8.2.1

Configure

python configure --without-snapshot --openssl-no-asm --shared --dest-os=android

Then in deps/cares/config/android/ares_config.h comment out

#define HAVE_GETSERVBYPORT_R 1

And run make (will take a while). Remember to have Termux aquire a wake lock so your phone doesnt go to sleep

Shared lib is out/Release/lib.target/libnode.so.57

[dominictarr]

oh yeah @mafintosh okay i'll try that.

[dominictarr]

wow, node's git repo is 1.9gb!

[dominictarr]

I managed to get it on my phone with 20 something mb to spare... not sure if this will work to be honest...

[ralphtheninja]

Maybe you could use curl instead to skip the complete history, e.g.

$ curl -sL https://github.com/nodejs/node/archive/v8.2.1.tar.gz > node.tar.gz

[ralphtheninja]

Or use --depth with git clone

$ git clone --depth=2 -b v8.x https://github.com/nodejs/node.git

[dominictarr]

@ralphtheninja I tried a shallow clone and it didn't work because first it clones it into .git then it checks it out which uses double. In the end what I did was local clone on my laptop to _node, then tar -c _node | ssh android@... tar -x which extracts it inplace without first placing the tar file on disk! it's now compiling in screen.

[dominictarr]

actually my phone has 20 gb available, but not within the linux container, and not sure how to fix that.

[dominictarr]

I left it going overnight, and it ended with this error:

/usr/bin/ld: cannot find -llog
collect2: error: ld returned 1 exit status
deps/openssl/openssl-cli.target.mk:195: recipe for target '/home/android/_node/out/Release/openssl-cli' failed
make[1]: *** [/home/android/_node/out/Release/openssl-cli] Error 1

Makefile:76: recipe for target 'node' failed
make: *** [node] Error 2

hmm, okay, so it can't find a library... liblog? is this part of node? I'm guessing that there are probably way more errors like this behind it

[aschrijver]

@dominictarr Did you manage to build the 32bit library?

I've been trying many different things with ndk build, but always run into errors somewhere. My latest try is even with a r17 ndk canary build: nodejs/node#14771

[dominictarr]

I didn't get passed that one. @mafintosh said he was gonna try on his rpi, but havn't heard back about that yet.
