Arm64 build #16

Open mauritslamers opened 7 years ago

mauritslamers commented 7 years ago

I would like to run NW.js on a PineBook (http://pine64.org). While the same processor is used as in the Raspberry PI 3 (ARM Cortex A53) the default distro is a pure 64bits Ubuntu Linux. While it would be theoretically possible to try to run the armv7 version with multilib, it would require quite a bit of extra disk space. Would it be possible to also include a 64bit release (arm64, armv8)? I sadly don't have a system available where I could try to compile it myself.

mauritslamers commented 7 years ago

Update: I managed to find a system where I could attempt to compile the arm64 version. I used the manual from https://github.com/LeonardLaszlo/nw.js-armv7-binaries/blob/master/docs/build-nwjs-v0.23.x.md. I managed to get rather far in the process but didn't manage to get a usable product. I found the following:

Update: I managed to solve the strip problem. I found that the patches such as https://github.com/jtg-gg/node-webkit/commit/73f745bfb7587f38031d4e39a86718b64656bd5a need to be adjusted a bit in order to make things work under arm64. For every mention of arm as platform or current cpu, an additional mention of arm64 should be made. In src/nw/content/nw/tools/package_binaries.py, I added 

                target['input'].append('nacl_irt_arm64.nexe')

under the existing arm line. Also in src/nw/content/nw/BUILD.gn the following should be added:

  else if (target_cpu == "arm64") {
    linux_strip_binary = "aarch64-linux-gnu-strip"
  }

and in src/nw/content/nw/nw.gypi the condition for arm stripping should also include the following:

            'target_arch="arm64"', {
              'variables': {
                'linux_strip_binary': 'aarch64-linux-gnu-strip',
                },
            },

This allows the process to almost finish. As mentioned above, the nacl support seems to be problematic in a similar way. The step gn gen out_gn_arm/nw --args="$GN_ARGS" fails because of missing definitions for arm64. Not including NaCl causes a problem for building the SDK version, as all the configuration scripts seem to automatically include NaCl when building the SDK.

jtg-gg commented 7 years ago

@mauritslamers thats great, nacl might not that important to many people so do you have a working build ?

mauritslamers commented 7 years ago

I think so, but I cannot create an SDK package to test because it requires nacl. I will try today to see whether I can adjust the packaging scripts to make an SDK without nacl.

mauritslamers commented 7 years ago

I managed to get a working arm64 package (added screenshot of a running nw.js on an arm64 platform). I adjusted the packaging script, commenting out all the lines where nacl was mentioned. In hindsight it is strange that the packaging script does not take the environment settings into account: even when explicitly disabling nacl during compilation it still tries to package it. What would be the best spot to upload the working arm64 version? [Edit: spelling]

LeonardLaszlo commented 7 years ago

I granted you collaborator rights. You can add your changes to the existing markdown files and modify the existing releases to include the 64 bit binaries.

plokko commented 7 years ago

Thank you @mauritslamers ! I was also struggling on getting an arm64 build with no results, i can't wait to try it out!

mauritslamers commented 7 years ago

I just updated the v0.23.7 release to include my arm64 build (thanks @LeonardLaszlo to grant me access!). As far as I can see, everything works as intended, but I didn't do test building. Also I assume that it should be renamed to -chrome-branding as I included the ffmpeg support in the build. Please keep me posted about your results.

plokko commented 7 years ago

It works on my Nanopi-k2 (Amlogic s905,on default image ubuntu-core xenial)! i had just to install few dependencies: sudo apt-get install -y libgconf-2-4 libxss1 thanks again!

mauritslamers commented 7 years ago

You're very welcome. In the end it was only possible because of the great building manual made by @LeonardLaszlo and the diffs created by @jtg-gg.

TagLoomis commented 6 years ago

Will we see a arm64 distribution for latest?

LeonardLaszlo commented 6 years ago

maybe one day if I get things done properly. First I'd like to automate the existing build process and use a CI system for the build. It is quite a hassle to do all these builds manually

ubergeek77 commented 5 years ago

In the meantime, would @mauritslamers perhaps be able to provide some arm64 binaries for some of the later NW.js versions? I would be very grateful to get an arm64 binary for something like version 0.30.

mauritslamers commented 5 years ago

@ubergeek77 I tried to see whether I could build 0.30, but that didn't work out because the https://github.com/jtg-gg/chromium.src seems to be missing the 0.30 branch for the arm patches. Will have a go at 0.28

mauritslamers commented 5 years ago

Remarks about the arm64 build of 0.28:

I am not crosscompiling, but compiling on a Pine64 under arm64 linux. This brings some extra challenges.

This gets us to the ninja compile step, which fails at the moment. More updates later.

ubergeek77 commented 5 years ago

You're amazing! Thank you very much for working on this.

mauritslamers commented 5 years ago

Update:

More changes:

The ninja compile step now runs without immediately crashing. More updates later.

mauritslamers commented 5 years ago

The ninja compile step now runs without immediately crashing.

After rather a while the compilation process fails because of a missing library, libXcursor.so.1 which it is searching for in the debian sysroot in build/linux/debian_stretch_arm64-sysroot/lib/aarch64-linux-gnu. The library is present on the system usually, in my case in /usr/lib/aarch64-linux-gnu. Symlinking libXcursor.so.1 in the debian sysroot, allows the compilation process to continue. More updates later.

mauritslamers commented 5 years ago

Update:

mauritslamers commented 5 years ago

Update: Getting step 3 to compile is rather complex

mauritslamers commented 5 years ago

Update: trying a few things in order to get libnw.so compiled. The only output currently is a directory full of libs, on which the 3rd compilation fails as it tries to link to libnw.so (through -lnw) which it cannot find as it does not exist.

mauritslamers commented 5 years ago

Update: I am still working on this, as compiling (and recompiling) on the Pine64 is very slow (only 2GB memory, and currently using usb-hdd for swap and storage. It also turns out that formatting an ext4 disk on ubuntu 18.04 and then using it under 16.04 causes issues, as ext4 under 18.04 uses checksums, which are not completely supported under 16.04. Once in a while it causes 16.04 to fail because of input/output errors, which can be solved by mounting it under 18.04, run fsck, then return it to the pine64 to continue. This might have to do with the pine64 running on an older kernel (3.10.104). I still have issues with getting libnw.so compiled. The out_gn_arm/nw/lib folder contains a libnw_base.so, but that obviously doesn't satisfy the node-nw compilation process.

Also working on an automated cross-compile build, using self hosted gitlab and gitlab-ci, as the entire compilation process takes multiple hours on modern hardware and services like Travis and AppVeyor only allow a maximum running time of one hour.

aspect commented 5 years ago

@mauritslamers what is your status on this? have you been successful with a cross-compile build? would trying to set up an arm64 VM help? https://wiki.ubuntu.com/ARM64/QEMU I can provide computing resources with SSH access (i.e. set up a VM on SSD and lots of RAM and provide SSH access) ... if this would help.

janrinze commented 4 years ago

Icestudio has migrated to nw.js 0.35. Any chance we will see nw.js 0.35 for armhf and aarch64? (i'd like both versions)

LeonardLaszlo commented 4 years ago

Unfortunately I don't have the time needed to tweak the builds.

k1r0s commented 3 years ago

sorry but TL;DR where I can download the bin in order to run it on arm64 systems?

jrd261 commented 3 years ago

I just managed to cross-compile 0.51.3 for arm64 (no sdk, no nacl). Starts up on my Jetson ARM64 device but I haven't really tested much. I'll work on documenting the steps and providing a Dockerfile.

LeonardLaszlo commented 3 years ago

@jrd261 please update the building scripts and open a PR.

jrd261 commented 3 years ago

It might take me a little to adapt my scripts as I used docker layer cache for the whole thing. Here's a synopsis on how I got it to work and maybe you guys will have some pointers (I don't know a whole lot about building with these tools). I'll work on getting this into a PR. I'll probably see if I can get an SDK version working first.

Installed sysroot with ./build/linux/sysroot_scripts/install-sysroot.py --arch=arm64

Great work! I also would like to run nwjs on my Jetson Nano. Can you provide binaries or instruction how to build? Thank you.

jrd261 commented 3 years ago

@pakimov2 I should have instructions PR'ed in a day or two, still cleaning it up.

You should be able to follow the build for arm7 in this repo with those two patches and extra build flags.

janrinze commented 3 years ago

@jrd261 your repository is still empty. I would like to try a native build on my NVIDIA AGX since it has plenty disk space left (200GB) and 8 cores with 32GB memory. It is running Debian Sid. So far my attempts have failed due to too many manual steps that are prone to errors.

jrd261 commented 3 years ago

@janrinze I opened a PR to this repo with the build steps. Please note my steps are for cross compiling from amd64.

NemoAlex commented 3 years ago

Any updates?

LeonardLaszlo commented 3 years ago

I integrated @jrd261's work into the building script. The non-SDK versions are built fine.

For the SDK build I am getting this error:

ERROR at //ppapi/native_client/src/untrusted/pnacl_support_extension/BUILD.gn:64:5: Assertion failed.
    assert(false, "unhandled target_cpu")

If you manage to fix this please send me the patch so I can integrate it to the building script.

LeonardLaszlo commented 3 years ago

You can find the artifacts under the Relaese tab.

janrinze commented 3 years ago

Quick update: icestudio is running with the aarch64 binaries. Not for the faint of heart: aarch64 is not a 'fully supported' platform for APIO thus bumping into various issues once icestudio is running. So far it's working and i will add info on the icestudio github issues for aarch64 related problems.

Does anyone here know how long it takes to run the complete build of the aarch64 binary? I'm willing to try it on my system but would like to know beforehand :-)
