I have checked out a specific tag in the flutter repo. Thats why the following warnings appear. This has never been a problem.

[!] Flutter (Channel [user-branch], 3.32.5, on openSUSE Leap 16.0 6.12.0-160000.5-default, locale de_DE.UTF-8) [170ms]
    ! Flutter version 3.32.5 on channel [user-branch] at /home/robert/flutter
      Currently on an unknown channel. Run `flutter channel` to switch to an official channel.
      If that doesn't fix the issue, reinstall Flutter by following instructions at https://flutter.dev/setup.
    ! Upstream repository unknown source is not a standard remote.
      Set environment variable "FLUTTER_GIT_URL" to unknown source to dismiss this error.

Version

9.1.0

Steps to Reproduce

• Add sentry_flutter as a dependency
• Use in code (e.g. Sentry.captureException(..))
• Build Linux Desktop
• Error about missing JVM, JAVA_HOME, etc.
• Install open-jdk-21-dev
• Build Linux Desktop again (previous errors not shown anymore)
• Unable to build because of mentioned error

Expected Result

Building for linux desktop continues to work

Actual Result

Building Linux application...
/usr/bin/ld: warning: crashpad_info_note.S.o: missing .note.GNU-stack section implies executable stack

[robertosw]

Other projects had similar issues: MolecularAI/aizynthfinder#194 .

When using execstack to check the executable stack flag for the library, an X is present:

$ execstack -q /home/robert/.../client/build/linux/x64/debug/bundle/lib/libsentry.so
X /home/robert/.../client/build/linux/x64/debug/bundle/lib/libsentry.so

From the man page of execstack:

-q: Query executable stack marking of binaries and shared libraries. For each file it prints either - when executable stack is not required, X when executable stack is required or ? when it is unknown whether the object requires or doesn't require executable stack (the marking is missing).

However, removing the executable flag does not fix the issue:

1. flutter clean
2. flutter pub get
3. flutter build linux --debug

/usr/bin/ld: warning: crashpad_info_note.S.o: missing .note.GNU-stack section implies executable stack
/usr/bin/ld: warning: crashpad_info_note.S.o: missing .note.GNU-stack section implies executable stack

4. execstack -c /home/robert/.../client/build/linux/x64/debug/bundle/lib/libsentry.so (-c removes the flag)
5. flutter run

fails, because the executable stack flag is added again

---

However, the two errors

/usr/bin/ld: warning: crashpad_info_note.S.o: missing .note.GNU-stack section implies executable stack
/usr/bin/ld: warning: crashpad_info_note.S.o: missing .note.GNU-stack section implies executable stack

disappeared after removing the executable stack flag

cc @vaind maybe you have more info here

Not really, looks like some hardening config specific to newer setups. Might necessitate changes upstream, let's move to sentry-native

[robertosw]

I just tried to run our application on windows and ran into issues there as well that were only happening because of the inclusion of the sentry_flutter package. I wanted to make sure I didn't skip on some setup-step thats mentioned in the docs, so I searched around a bit. In the Migration Guide for Flutter Desktop I found that native crash handling is now done with crashpad and can be disabled.

If I disable crashpad everything builds and runs just fine. These errors are only happening because of crashpad.

• linux: SENTRY_NATIVE_BACKEND=none flutter run --debug --device-id linux
• windows powershell: $env:SENTRY_NATIVE_BACKEND="none"; flutter run --debug --device-id windows

Note that flutter run --debug --device-id linux --dart-define=SENTRY_NATIVE_BACKEND=none does not work.

These are the errors I get when trying to run our flutter app for windows with crashpad enabled (flutter run --debug --device-id windows)
