error: failed to run custom build command for `lemmy_utils v0.16.3...

[JohnnyBackflip]

I can't build the Project.

I did this: https://join-lemmy.org/docs/en/contributing/local_development.html

It failed @ "cargo run"

cargo run

Any Help?

[dessalines]

git pull --recurse-submodules

or

git submodule update --init --recursive --remote

[JohnnyBackflip]

git pull --recurse-submodules

or

git submodule update --init --recursive

Fetching submodule crates/utils/translations Already up to date.

Didn't work, same error

edit: https://join-lemmy.org/docs/en/contributing/docker_development.html works tho

[Nutomic]

That uses the same files, so if Docker build works, local build should work as well. Does git status show anything out of date? And does crates/utils/translations/translations/en.json exist?

[JohnnyBackflip]

GIt status:

git status On branch main Your branch is up to date with 'origin/main'. nothing to commit, working tree clean

crates/utils/translations/translations/en.json exists.

[dessalines]

Its clearly missing otherwise you wouldn't be getting a nosuchfilefound excepotion. Show us the output of

head crates/utils/translations/translations/en.json

[JohnnyBackflip]

[Nutomic]

Other files mentioned in the error message also exist? Then that error doesnt really make sense. Maybe try a clean build.

[dessalines]

IE cargo clean

[JohnnyBackflip]

IE cargo clean

didn't work, same error after doing cargo run again

Other files mentioned in the error message also exist?

No, that's the only error

Maybe try a clean build.

I can try again tomorrow

thanks for helping

[SamWhited]

I have the same issue and a clean build does not appear to have fixed anything. Maybe this is some missing dependency for translations? It doesn't say what file is missing.

[dessalines]

Try these commands:

git submodule init
git submodule update --recursive --remote
cargo run

[JohnnyBackflip]

Try these commands:

git submodule init
git submodule update --recursive --remote
cargo run

Thanks but this doesn't solve the problem.

[SamWhited]

I can confirm that I already checked out submodules and all the files are there.

[dessalines]

The CI would be failing if that wasn't working properly, but I'll test it locally in a new folder.

[SamWhited]

This could also be a permissions issue, though I'm just taking a stab in the dark. The error message is the same, IIRC because it doesn't know the difference between a file that doesn't exist and one it doesn't have access to. But again, the error message doesn't list what file it's asking for so the submodule that it's building could be a red herring and this is some dependency that it can't find or similar. Maybe the error message needs to be improved as a starting point?

[dessalines]

I just ran those exact three commands on a fresh clone, and everything worked fine. The only thing I can suspect, if the files are there:

• Old rust version
• Not running cargo clean
• Not using --remote when cloning the submodules.

[dessalines]

I'm not sure how permissions could get messed up, unless you cloned the repo with a different user that you added submodules.

[dessalines]

Almost guaranteed its the rust version, or not properly installing rust using rustup. No other explanation for why a cargo run would fail, but a docker build working on the same files passes.

[SamWhited]

Please don't close this, it is still affecting two people. We are not lying when we say we ran cargo clean, or when we say that we initialized submodules. Here is an exact session starting from scratch that, on my machine at least, reproduces the issue.

error: build failed

[JohnnyBackflip]

The reason is a wrong Rust version. Some repo is out of date.

Here is how to solve it: Rust must be v 1.60.0

rustc --version

rustc 1.60.0

Do this:

sudo apt update sudo apt upgrade curl https://sh.rustup.rs -sSf | sh

Install it.

Then:

source $HOME/.cargo/env

check your Version again:

rustc --version

now it compiles.

[SamWhited]

Ahh, I see, it looks like Rust on Fedora is 1.59.0. I'm stuck with the default fedora packages for <reasons>, so I won't be able to build since it seems to require a very recent version. Oh well, thanks for all the help.

[dessalines]

You're gonna wanna use rustup to install rust.

[SamWhited]

I can't, sadly.

[happysalada]

weirdly enough, I'm hitting this on nixos with rust 1.61. how weird. Also testing on lemmy 0.16.4 when the submodules are not there I hit a different error

Error: FileRead { file: "translations/email/en.json", source: Os { code: 2, kind: NotFound, message: "No such file or directory" } }

which is clear and correct. But when the submodules are there, I hit

Error: Fmt(Os { code: 2, kind: NotFound, message: "No such file or directory" })

I was wondering what the Fmt in front of the error meant. I discovered it's actually just a missing rustfmt binary. Adding the rustfmt dependency to my build, just fixed it. Just in case anyone comes here again.

[Nutomic]

I opened https://github.com/LemmyNet/lemmy/issues/2333 about specifying a minimum supported rust version.

@happysalada There should be no need to install rustfmt for a simple build. Which command did you run to get that second error?

[happysalada]

just cargo build you can see the other people in the thread have exactly the same error (it starts with Fmt). Not sure why, but it looks like rustfmt is required here. I don't think it appears on most machines since people have it by default, however, on some build environments with little dependencies this is where we see the error. (I'm coming here from updating lemmy on nixos).

[Nutomic]

@happysalada Could you test if a toolchain file can solve the problem for you? I suppose it should look something like this, but not sure which components are really needed.

[toolchain]
channel = "stable"
components = [ "rustfmt", "rustc-dev" ]

It would also be nice to show a better error message in case a user forgot to sync the submodule, but i cant think of any good way to do that.

[happysalada]

Depending on the distribution, a toolchain file might not work. On nixos for example, rust doesn't use a toolchain file, you have to pull separately each component manually. Nix won't allow you to download something from the internet without defining how to build it from source or its sha256. I don't know about other distributions. For nixos, we have to add "rustfmt" to the list of build inputs, there is unfortunately no way around it.
