Can't install on arm64

[babolivier]

Hi there,

As there seems to be no binary for the arm64 architecture, leveldown won't install on my Pine64 with a simple npm install (so as a dependencie, which is how I want to use it).

Here's some of my Node.js process variables:

[brendan@pine64 data-system]# node
> process.arch
'arm64'
> process.platform
'linux'
> process.versions
{ http_parser: '2.5.2',
  node: '4.4.7',
  v8: '4.5.103.36',
  uv: '1.8.0',
  zlib: '1.2.8',
  ares: '1.10.1-DEV',
  icu: '56.1',
  modules: '46',
  openssl: '1.0.2h' }
> 

Would it be possible to have binaries built and released for this architecture?

@babolivier Since it's linux it should be trivial to build during npm install. If there are no prebuilt binaries it will fallback to compiling leveldb and leveldown .cc files.

@babolivier What kind of error message do you get? Please post the results of npm i leveldown --verbose to a gist and share that link.

Hi @ralphtheninja, here's the gist: https://gist.github.com/babolivier/441ad19444d66fc4e9b3038066ad3e9f

Well, sorry for reading the NPM log too quickly, this doesn't seem to happen because of the lack of a binary, but because of this:

../deps/leveldb/leveldb-1.18.0/port/atomic_pointer.h:211:2: error: #error Please implement AtomicPointer for this platform.

Ok, so it's having problems while compiling. Unfortunately this seems to be related to the LevelDB c++ lib. You might want to dig around there to see if that has been fixed or not.

[babolivier]

So I looked around a bit and came accross this issue I didn't see in my first search: #268

As I can guess, support for my architecture will be added in 1.19, which hasn't been released yet. As the last version dates from 2014, I think I'll have better chances at trying to compile leveldb on my platform, so that's what I'm gonna do.

[babolivier]

No success here (LevelDB having not a single build instruction doesn't help). However, I saw this commit on a fork and wondered if that wouldn't be a nice idea to have it in leveldown, as a quickfix for people using an arm64 architecture while waiting for 1.19?

@babolivier So @juliangruber has landed 1.19 #299 (edit wrong link)
If you want to validate this bug against it and feedback we would be delighted to hear from you

Confirmed compile & test are 👍 on ARM64 for the leveldb-1.19 branch.

Hi all, thanks @rvagg for testing, I just didn't have the time to test if everything was OK in the last few days.
If it works on ARM64, then I guess I can close this issue 😄
