To reproduce the build failure on the current master branch you can run

nix build nixpkgs#pkgsCross.riscv64.gn

There is already gn of 2021-08-08 in nixpkgs, and this version already includes risc-v support. https://github.com/NixOS/nixpkgs/blob/b4fc1d4a6f6cfdebf711fd00be7a5f13ace2af1b/pkgs/development/tools/build-managers/gn/rev1924.nix

Bump of default gn version may introduce breakage in dependent packages, as gn provides no guarantees for backwards compatibility. Maybe just explicitly use gn1924 for dependencies needed in RISC-V?

Any news on this happening?

There seem to be four packages, depending on gn, namely skia, v8, oni2 and chromium:

If this bump doesn’t break them, it should be safe to make it. However, I currently don’t know how to do it, I don’t have access to x86 machine with Nix.

@SeTSeR Did ofbrog ever attempt to build?

I don't have much experience with ofborg myself, as I don't run it much, but it seems something was run as we can see from the checks:

However, I can't access logs now, maybe the check is too old and I have to start it again.

I have rebased this PR and changed it to bump to the gn version (2024-01-22) used in the current chromium stable version. Only a handful of packages use gn, and some always override it. The exhaustive list is

non-override uses

• aseprite
• neovide
• libsForQt5.qt5.qtwebengine
• qt6.qtwebengine
• python31XPackages.skia-pathops

override uses

• chromium
• v8

I have successfully built all of them on x86_64-linux. The package oni2 was removed from nixpkgs since opening this PR.

Pinging maintainers of the maintainers of the direct reverse deps: skia-pathops (@barinov274), qt5.qtwebengine (@matthewbauer) and of qt-6 modules (@milahu, @NickCao). Can you take a look at this as well?

Bumped to gn used in chromium 126. I decided not to bump to gn 2024-06-06 (revnum 2174) from chromium 127 because it requires relaxing hardening flags.

I have again successfully built the following direct reverse dependencies on x86_64-linux:

• skia-aseprite
• neovide
• libsForQt5.qt5.qtwebengine
• qt6.qtwebengine
• chromium
• v8
• python31XPackages.skia-pathops
