isar
Running in Docker container struggles to find libisar.so
Hey, I'm using isar in my dart project and everything works as expected regarding to initializing isar core on windows. The only issue happens when I try building the app and dockerize it. It looks like the isar lib cannot be loaded or localized. I even tested if the lib file is being downloaded correctly and it is:
Code sample
Future<void> init(InternetAddress ip, int port) async {
print(Platform.operatingSystemVersion);
try {
await Isar.initializeIsarCore(download: true);
} catch (e) {
print(e);
}
final isarlib = File('/app/bin/libisar.so');
print('isar lib exists: ${isarlib.existsSync()}');
...
Output

How is that possible? I manually checked if the file is there. I even tried to copy it to the container in docker-compose but the outcome is the same: File is there, but No such file or directory :/
Details
- Platform: Docker ( Linux 5.10.16.3-microsoft-standard-WSL2 )
- Dart version: 3.0.2

I am having the same issue.
I am using dart_frog and it works fine when I use dart_frog dev.
When I build, create docker image and run it then I get the following error:

Try : RUN apt-get update & apt-get install -y gcc-multilib libgcc1
Would that be as part of the docker file or where would that be inserted?
Dockerfile:
FROM dart:3.2.0-sdk AS build
RUN apt-get update && apt-get install -y
gcc-multilib
libgcc1
WORKDIR /app COPY pubspec.* ./ RUN dart pub get
COPY . . RUN dart compile exe bin/server.dart -o bin/server
FROM ubuntu COPY --from=build /app/bin/server /app/bin/ COPY --from=build /app/bin/libisar.so /app/bin/
EXPOSE 8080 CMD ["/app/bin/server"]
One bad point is that ISAR may not work in all scenarios. For example, it worked on my local wsl, but when I took it to azure, it didn't work. https://github.com/isar/isar/issues/1299 My best choice was to remove it from my project. I would love to use it, but I don't think now is the time.
