Reproduction Steps

I've tried three times to build and it happens every time.

Additional information

I'm running up to date Fedora. I'm very eager to get the build working because this software would allow me to daily-drive Linux.

Thanks for the detailed report. I just made the switch to Linux like 4 months ago. I totally get the excitement. Let me see if I can help you.

Could you share which branch/tag you cloned from?

The root cause is that the V8 build patch (gclient_paths.patch) no longer applies cleanly to the version of gclient_paths.py that gclient pulls down — this happens when upstream V8/depot_tools updates the file and the patch context no longer matches line 20.

A few things worth noting:

1. This is a known fragility in builds that depend on patching depot_tools internals. The fix is to regenerate gclient_paths.patch against the current upstream file, which is a maintainer-side task.
2. Your environment is not the cause. The Fedora/x86_64 combination is fine; the Docker layer isolates the build from your host OS.

If you want to try fixing it locally while we address this properly, here's how:

Step 1 — Find the patch file in the repo

find . -name "gclient_paths.patch"

Step 2 — Find the depot_tools version being pulled

Search for depot_tools or gclient in the CMake scripts to find the specific commit or branch being checked out during the build.

Step 3 — Regenerate the patch

git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
cd depot_tools
git checkout <commit-used-by-build>
# Apply the same logical change manually, then:
git diff gclient_paths.py > gclient_paths.patch

Replace the patch file in the repo with the regenerated one and rebuild.

If you're not comfortable editing patches, paste the output of cat <path>/gclient_paths.patch here, and I can try generating a corrected version for you.

I was able to build past this point using the following gclient_paths.patch file:

I also successfully installed it via sudo dnf install deploy/packages/euro-office-desktopeditors-9.3.1-dev.0.x86_64.rpm

I only replaced the x86 patch file, as I'm not building for arm. I'm unsure if it'd be the same for arm, though I'd imagine it is.

Thank you for tracking this down and sharing the corrected patch — that saved us a lot of time. We've incorporated your fix (covering both x64 and arm64) and opened a PR here: Euro-Office/core#129

Once it's merged and picked up in a build, this should work out of the box for anyone hitting the same issue.

[pjahelka]

I confirm that the updated patch works and results in a installable, working package on Fedora x86. Thank you!

[Duckle29]

Cool!
I just followed your instructions @pplupo, so thanks for those! :D

[Bristolian1962]

Sadly, I'm a total newcomer to all of this, and haven't the foggiest on how to build a desktop app - the Instructions are like pie in the sky to me!

No worries — you don't need to build it yourself. If you let me know which Linux distribution you're on (Ubuntu, Fedora, Debian, etc.) and whether it's x86_64 or ARM, I can TRY building a pre-built installer and share it for you to try directly.

Note that it'll be a development build rather than a formal release, but it should be fully functional for daily use.

[Bristolian1962]

Thank you - I'm on Windows 11 though, not Linux!

It can be built for Windows too. Unfortunately, I don't have a Windows machine anymore, so I can't do it for you. :-( Maybe someone else can. Or you may have to wait a little longer for the official first release.

[Bristolian1962]

Thank you anyway :).
