Android build failing due to ld.lld being unable to find libraries to link with

[ajaypillay]

Hi, I'm on Fedora 39 and I'm trying to build for Android with pnpm tauri android build. The errors are:

  = note: ld.lld: error: unable to find library -lgobject-2.0
          ld.lld: error: unable to find library -lgdk-3
          ld.lld: error: unable to find library -latk-1.0

          ld.lld: error: too many errors emitted, stopping now (use --error-limit=0 to see all errors)
          clang: error: linker command failed with exit code 1 (use -v to see invocation)

How should I be going about fixing this? My clang version is 17.0.6 and I'm on Tauri 2.0.0-beta.

Thanks to @simonhyll's help on Discord, this has been resolved. The issue was I neglected to omit an import from non-Linux (desktop) targets. As I had to get media sharing working in my app in Fedora 39, I followed what was laid out here: #8426 (reply in thread)

However, the offending line in my codebase was:

use webkit2gtk::{SettingsExt, WebViewExt};

which should've been:

#[cfg(target_os = "linux")]
use webkit2gtk::{SettingsExt, WebViewExt};

This caused the build to attempt to link with the desktop libraries, which caused it to fail.
