Issues building for void-linux

[shizonic]

After unpacking a release tarball (e.g. 1.4.6) the third_party folder is empty. Guess the step https://github.com/denoland/deno/blob/master/.github/workflows/ci.yml#L61 needs to be updated...

[lucacasonato]

Actually, why do you want the third_party folder? It shouldn't be required for building Deno.

[shizonic]

In this case I don't need it. Thought it is required because my build always failes.

Background: Try to package it for the Void linux distribution.

May you help me whats going wrong? Here is the Travis CI build log: https://travis-ci.org/github/void-linux/void-packages/builds/735400951

[lucacasonato]

I think this distro only ships with musl right? Deno requires glibc right now. See #3711

Also Deno does not support i686.

[shizonic]

Not it ships with glibc too! This isn't the problem becsuse I can skip the musl builds. But it even doesn't build on glibc.

[lucacasonato]

The minimum supported rust version is 1.46.0. It seems your release is older. Also you need a very recent version of clang: https://github.com/denoland/rusty_v8#build-v8-from-source

[shizonic]

Oh okay this may be the cause. I will give it a try. Thanks for your help!

[shizonic]

As far as I see void

The minimum supported rust version is 1.46.0.

Where did you see that? As far as I see Voidlinux uses version 1.46.0: https://github.com/void-linux/void-packages/blob/master/srcpkgs/rust/template#L7

Also you need a very recent version of clang.

LLVM 10.0 works too, right? (https://github.com/void-linux/void-packages/blob/master/srcpkgs/llvm/template#L3)

[lucacasonato]

LLVM 10.0 works too, right? (https://github.com/void-linux/void-packages/blob/master/srcpkgs/llvm/template#L3)

LLVM is a compiler backend, and not the same as something like gcc or clang (which is the compiler frontend that parses c / c++ and translates it LLVM IR). rusty_v8 hasnt been built with anything other than recent clang for a long time, so anything else (like gcc) likely won't work.

[piscisaureus]

Note that rusty_v8 will actually download clang automatically so it should "just work".
But we don't test on void-linux so I'm sure there will be some surprises.

[shizonic]

Thanks @lucacasonato and @piscisaureus for your great explanations and help. I really appreciate it!

Actually I guess the problem has something to do with gn because of this error log:

  is `gn gen` not installed?

I gonna investigate further. Love deno and want it be packaged on Voidlinux.

[piscisaureus]

gn should also be automatically installed though.

I wonder if you’re on a 32 bit system. We don’t support 32 bit builds.

hmm okay

I wonder if you’re on a 32 bit system. We don’t support 32 bit builds.

Voidlinux supports many archs: x86_64, i686, aarch64, armv7l, armv6l and all for glibc and musl libc. I can't build deno on any... even x86_64 glibc. Have a look at: https://travis-ci.org/github/void-linux/void-packages/builds/735400951

Gn is typically downloaded by the cargo_gn crate somewhere into the build directory.
You can bring your own, but then you need to set the GN environment variable to point at it.
We download it from here btw - https://github.com/denoland/ninja_gn_binaries/tags

Oh okay I used https://gn.googlesource.com/gn

[shizonic]

How can I prevent fetching precompiled binaries during build process? See: void-linux/void-packages#22043 (comment) and void-linux/void-packages#25436 (comment)

Any progress on this?
