GPU access using engine built with --disable-desktop-embeddings #153196
Description
Steps to reproduce
- switch to main channel
- Build flutter engine (main) using
--runtime-mode=debug --embedder-for-target --enable-fontconfig --disable-desktop-embeddings --no-build-embedder-examples --enable-impeller-3d --no-lto --no-goma --no-rbe --no-stripped --no-enable-unittests - Follow steps in this article to create and run app: https://medium.com/flutter/getting-started-with-flutter-gpu-f33d497b7c11
Expected results
Expect symbols to be exported by engine build
Actual results
══╡ EXCEPTION CAUGHT BY RENDERING LIBRARY ╞═════════════════════════════════════════════════════════
The following ArgumentError was thrown during paint():
Invalid argument(s): Couldn't resolve native function 'InternalFlutterGpu_Context_InitializeDefault'
in 'package:flutter_gpu/gpu.dart' : No asset with id 'package:flutter_gpu/gpu.dart' found. No
available native assets. Attempted to fallback to process lookup.
.desktop-homescreen/lib/libflutter_engine.so: undefined symbol:
InternalFlutterGpu_Context_InitializeDefault.
Indicates the build is not exporting the symbols even though
#define FLUTTER_GPU_EXPORT __attribute__((visibility("default")))
...
FLUTTER_GPU_EXPORT
extern Dart_Handle InternalFlutterGpu_Context_InitializeDefault(
Dart_Handle wrapper);
flutter_test is correctly exporting the GPU symbols.
I'm using this to list symbols
nm -S flutter_tester | c++filt |grep InternalFlutterGpu
nm -S libflutter_engine.so | c++filt |grep InternalFlutterGpu
