[bug] `cargo tauri build` fails to build appimage with "error running appimage.sh"

[malaire]

Describe the bug

When running cargo tauri build the deb is built successfully but building appimage fails with following error:

...
   Compiling app v0.1.0 (/y/projects/A-Z/D/dioxus-testing/tauri-bug/src-tauri)
   Compiling webkit2gtk v0.18.0
   Compiling tauri-runtime v0.10.2
   Compiling tauri-runtime-wry v0.10.2
    Finished release [optimized] target(s) in 5m 23s
    Bundling my-app_0.1.0_amd64.deb (target/release/bundle/deb/my-app_0.1.0_amd64.deb)
    Bundling my-app_0.1.0_amd64.AppImage (target/release/bundle/appimage/my-app_0.1.0_amd64.AppImage)
       Error failed to bundle project: error running appimage.sh: error running appimage.sh: `No such file or directory (os error 2)`: No such file or directory (os error 2)

Reproduction

$ cargo install tauri-cli
$ mkdir tauri-bug
$ cd tauri-bug
- create `ui/index.html` with contents given in https://tauri.app/v1/guides/getting-started/setup/html-css-js/
$ cargo tauri init
App name           : My App
Window title       : My Window
Web assets location: ../ui
Dev server URL     : ../ui
$ mkdir src-tauri/.cargo
$ echo "build.target-dir = \"target\"" > src-tauri/.cargo/config
$ cargo tauri dev
; succeeds
- change bundle identified in `tauri.conf.json` to "my.test"
$ cargo tauri build
; fails

Note: .cargo/config is because of #4632 to override the global value I have.

Expected behavior

Build should succeed and create appimage file.

Can you re-run it with the verbose flag so that we hopefully can see where it fails exactly? cargo tauri build --verbose

Log after deleting targetand running cargo tauri build --verbose 2>&1 | tee log:

Full log attached.

btw, there is no appimage.sh file anywhere under target directory, but there is release/bundle/appimage/build_appimage.sh

Meh, hoped for a more helpful log/error x) Thanks nonetheless!

but there is release/bundle/appimage/build_appimage.sh

Sounds like a side effect of the target-dir setting to me. Gonna double check asap.

[malaire]

Problem was that I had missed installing librsvg2-dev.

After disabling my global and local target-dir setting, cargo tauri build --verbose gave a lot of debug info, ending with:

...
[gtk/stderr] No package 'librsvg-2.0' found
[gtk/stderr] /home/malaire/.cache/tauri/linuxdeploy-plugin-gtk.sh: there is no 'libdir' variable for 'librsvg-2.0' library.
[gtk/stderr] Please check the 'librsvg-2.0.pc' file is present in $PKG_CONFIG_PATH (you may need to install the appropriate -dev/-devel package).
ERROR: Failed to run plugin: gtk (exit code: 1) 
       Error [tauri_cli] failed to bundle project: error running appimage.sh: error running appimage.sh: `failed to run /y/projects/A-Z/D/dioxus-testing/tauri-bug/src-tauri/target/release/bundle/appimage/build_appimage.sh`

I have no idea why target-dir setting would hide debug info, but looks like it does.

[FabianLars]

Well, actually there are 2 issues. The first one (the one you initially posted) is indeed because of target-dir, and you need to remove both the global and local settings for it to work again (which you did).
The second one was like you said a missing dependency, but this happens way after the first issue.

[malaire]

Yes, I just noticed that if I don't have any target-dir setting build now succeeds.

But if I then add local build.target-dir = "target" (which should be no-op without global setting) build then fails.

[FabianLars]

Yeah, super weird. i'm looking into it right now and gonna try to fix 4632 while i'm at it.
