Build error: App built from tarball has GUI broken

[ItachiSan]

Hello,

Creating this as a blank issue since the templates are not really matching this one.
Also, I will replace certain Arch specific terms with more generic ones.

Problem

Users are not able to build Jan from a source tarball, for example:
https://github.com/janhq/jan/archive/refs/tags/v0.8.3.tar.gz

Context

I am an Arch user and use Jan via the AUR.

The "official" package is available here: https://aur.archlinux.org/packages/jan

This build script requires downloading the whole Jan repository that is over 2GB.
This can be heavy if a person clears the Git repo folder.

I've then tried to modify the build script to use the tarball, with a big failure

Expected

1. Modify build script to use tarball rather than Git repo
2. Run build script
3. App is built, install app
4. App works

What happens

The GUI is broken, for some reasons; there is no clear log of broken UI.

Resolution

Investigate why the Git metadata is required for a successful GUI.

Additional informations

I'm attaching the terminal logs of both tarball and regular builds, plus the screenshot of how the GUI looks like.

Tarball build

jan_tarball.log

Git tree build

jan_git.log

This build script requires downloading the whole Jan repository that is over 2GB.

While I take a look at this issue, you can do a shallow clone in order to prevent clone of entire history.

Update: Works when build from tarball

[ItachiSan]

@qnixsynapse can you tell me exactly how you performed the build?
E.g. OS, specific tools versions et cetera, commands

[qnixsynapse]

Just ran make build, it creates a bundle of deb and rpm, you can extract the deb and place it in appropriate place. Make sure to copy all assets otherwise it won't work.

OS: Arch Linux, no specific tools otherwise mentioned in this repo.

[ItachiSan]

If that is so, it means the build script grab some stuff for the Git repo that is not present in the modified PKGBUILD...
Will check later

[ItachiSan]

Hi @qnixsynapse, I still have the issue.

To streamline the build, I have the following build.sh script:

#!/bin/bash

cd $(readlink -f $0 | xargs dirname)

echo "--> Initial setup..."
export NVM_DIR="$PWD/nvm"
export YARN_CACHE_FOLDER="$PWD/yarn-cache"
export RUSTUP_TOOLCHAIN=stable
export COREPACK_HOME="$PWD/corepack"

source /usr/share/nvm/init-nvm.sh
nvm install 20
corepack enable
corepack prepare yarn@4.5.3 --activate

echo "--> Preparing sources"

if [ -n "$GIT_BUILD" ]
then
    echo "-> Build type: Git"
    git clone ../jan jan-git
    cd jan-git
else
    echo "-> Build type: tarball"
    tar xf ../jan-0.8.3.tar.gz
    cd jan-0.8.3
fi

echo "--> Building"
make build

echo "--> Running"
./src-tauri/target/release/Jan
cd ..

In the parent folder of the workdir I have both the tarball and a bare clone of the repository.
The script is executed via: [GIT_BUILD=1] ./build.sh

I then have this result:

Tarball

Git clone

[qnixsynapse]

echo "--> Running"
./src-tauri/target/release/Jan
cd ..

^^^ This is problematic since you are currently in jan-0.8.3 dir

[ItachiSan]

How to run it then?
And why this is fine for Git builds but not tarballs?

[qnixsynapse]

Please try

cd src-tauri/target/release/
./Jan

[ItachiSan]

No change whatsoever:

Here is the log:
