Facing error while cross-compiling Chromium for RISC-V64.

[Sharath]

Hi Team,

I am attempting to build the Chromium browser for a RISC-V64 architecture board running Ubuntu 22.04 with a Wayland desktop environment.
I am cross-compiling from an Ubuntu 22.04 x86-64 platform.

Below are the steps I have followed:

# Update package lists
sudo apt-get update

# Install depot-tools and add to PATH
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
export PATH=$PWD/depot_tools:$PATH
source ~/.bashrc

# Fetch the Chromium source code
mkdir chromium && cd chromium
fetch --nohooks chromium
cd src/

# Install build dependencies
./build/install-build-deps.sh

# Configure build arguments for RISC-V64 with Wayland
gn args out/riscv64-wayland

The build arguments I'm using are:

target_os = "linux"
target_cpu = "riscv64"
use_ozone = true
ozone_platform_wayland = true
angle_use_wayland = true
is_debug = false
symbol_level = 0
is_component_build = false
ffmpeg_branding = "Chromium"
proprietary_codecs = false
cflags_cc = [ "-Wno-error=deprecated-declarations" ]
use_siso = false

# Install sysroot for RISC-V64
./build/linux/sysroot_scripts/install-sysroot.py --arch=riscv64

# Sync dependencies and generate build files
gclient sync
gn gen out/riscv64-wayland

# Build Chromium
autoninja -C out/riscv64-wayland chrome

During the ninja build step, I'm encountering the following error:

ninja: Entering directory `out/riscv64-wayland'

Could someone please assist me in resolving this issue during the cross-compilation of Chromium for the RISC-V64 architecture?
It would be really helpful if you share some build steps for chromium for riscv64.

Thank you in advance for your assistance.

Best regards,

Hi,

The short answer is that riscv generally isn't a supported build configuration. (We might have a bot that builds cronet for riscv, but not the whole browser.) So you're likely to run into all kinds of issues.

For this particular problem, https://issues.chromium.org/issues/40177365 has some background.

This here https://source.chromium.org/chromium/chromium/src/+/main:base/process/process_metrics_posix.cc;l=115?q=mallinfo2%20f:base%2F%20f:process_me attempts to use mallinfo2 if the glibc in your sysroot is new enough (>= 2.33). It looks like you're using the Debian Trixie sysroot, which according to https://packages.debian.org/source/trixie/glibc should be 2.41, so it should work. You'd have to figure out why mallinfo2 isn't being used in that file.

(Or, if you'd prefer to paper over the problem, you could also set `treat_warnings_as_errors = false` in your args.gn. That's not recommended, of course. It looks like you tried this with `cflags_cc = [ "-Wno-error=deprecated-declarations" ]`, but cflags_cc can't be set in args.gn.)

Good luck,

Nico

Hi,

Please add treat_warnings_as_errors=false to your GN args as the unofficial chromium RISC-V port is currently not warning-free.
Here is the configuration I use in my downstream CI:  https://github.com/riscv-forks/chromium-riscv/blob/main/.github/workflows/ci.yml 

Some of the RISC-V support patches haven't made it into the Chromium source tree, so you will need to apply them manually.

For reference, here is the current two patches necessary for passing the build:

 # Sandbox
 git fetch https://chromium.googlesource.com/chromium/src refs/changes/20/4935120/11 && git cherry-pick FETCH_HEAD
 # Swiftshader
 git -C third_party/swiftshader fetch https://swiftshader.googlesource.com/SwiftShader refs/changes/29/75929/2 && git -C third_party/swiftshader cherry-pick FETCH_HEAD

Hi Nico Weber and Levi Zim,

Thank you for your replies.

Following your recommended steps, I successfully applied the Git patches and cross-compiled Chromium for riscv64. I then transferred the build directory to the riscv64 board and launched the browser. While Chromium starts successfully, I encounter issues loading websites, receiving "can't open this page" and "Aw, Snap!" errors. Additionally, the Customize and Control menu is non-functional.

         
For reference, here are the terminal logs from the browser launch:

Could you please advise on the specific steps required to resolve these runtime issues?

Thank you for your continued support.

Hi Nico Weber and Levi Zim,

Thank you for your replies.

Following your recommended steps, I successfully applied the Git patches and cross-compiled Chromium for riscv64. I then transferred the build directory to the riscv64 board and launched the browser. While Chromium starts successfully, I encounter issues loading websites, receiving "can't open this page" and "Aw, Snap!" errors. Additionally, the Customize and Control menu is non-functional.

         

Note that the SIGILL here does not necessarily mean an illegal instruction, it could also be a failing assertion or an unreachable assertion.

Just in case the SIGILL is real, you may need to check the RISC-V ISA string of your board.
Currently the build targets rv64gc.

 

For reference, here are the terminal logs from the browser launch:

It appears that chromium crashed in V8 code. Since riscv64 V8 support is seperated maintained, it can lag behind sometimes.
So such breakage or even failing the compilation is not completely unexpected.
You can search riscv related CLs in https://chromium-review.googlesource.com that may address it.

Alternatively, you may try to debug it by lanuching chromium with gdb.

The seccomp-bpf failures can be safely ignored. It is not related to the crash but actually a crash nested inside a crash.
