quarkus: Quarkus Awt extension doesnt work after upgrading to 3.2.3-Final when using native build

@aylwyne Just use a Quarkus version >=3.4.0. The build adds the necessary files automatically to the function.zip.

Thanks. I somehow missed the comment a few back linking to the specific fix in 3.4.0.

Hello @Karm , ah perfect, thanks for your support.

@Karm I created a small reproducer here which tries to convert some HTML into a PDF. When you compile this natively, upload the function.zip to AWS and run the lambda, you get the above mentioned UnsatisfiedLinkError.

Hello @gefloh, the problem is indeed just the missing libraries. I used your code to create my own AWS Lambda and it fails the way you described:

❌

✔️

When I manually added the .so files and re-uploaded the Lambda, it all went well:

…returning it me a bunch base64 encoded bytes. When I decoded it and jammed it into a .pdf file, it opened just fine for me, showing a caption “Test”:

I’ll proceed and fix this in Quarkus presently.

@gefloh Thx. I’ll take a look with my AWS.

I have managed to solve the bug for our case that @billapepper was asking about.

In our case we had this in our docker native build in a file called .dockerignore

*
!target/*-runner
!target/*-runner.jar
!target/lib/*
!target/quarkus-app/*

When the native build runs it adds the native libraries to the builds /target directory.

When the Dockerfile.native was building the copy command

COPY target/*.so /work

It was ignoring the *.so files due to the * in .dockerignore.

I have updated the .dockerignore file to

*
!target/*.so
!target/*-runner
!target/*-runner.jar
!target/lib/*
!target/quarkus-app/*

Now the native libraries are included in our docker image and the AWT processing for image resizing works.

As a note a lot of the examples in https://github.com/quarkusio/quarkus-quickstarts/tree/main for example https://github.com/quarkusio/quarkus-quickstarts/blob/main/spring-web-quickstart/.dockerignore have the same incorrect setup, as a lot of people possibly copy these examples as a starting point, might be worth checking there to make sure that the *.so files are actually being included in your docker image under /work.

One thing to note the files in the AWT example https://github.com/quarkusio/quarkus-quickstarts/blob/main/awt-graphics-rest-quickstart/.dockerignore actually has the allow in the docker ifgnore for the *.so libraries

@gefloh Could you whip up a small reproducer project I can use with my AWS account? AWS Lambda is a Linux running somewhere and we must copy the needed libs alongside the main Quarkus application executable to it.
