Could NOT find JNI #21

Not sure if this is a Bug or me not knowing enough about Cmake and Java. When I add the extension

sdk-extensions:
  - org.freedesktop.Sdk.Extension.openjdk1

I run into this error while building a CMAKE module:

INFO RT-extension not found. glTF import/export will be built without Open3DGC-compression.

Is JNI part of this extension or is there a way of adding it? Sorry for using the issue tracker for support question.

Using this in the manifest I could get the number of errors down:

build-options:
  env:
    PATH: /app/bin:/usr/bin:/usr/lib/sdk/openjdk11/bin
    JAVA_HOME: /app/jre
    CMAKE_JAVA_INCLUDE_PATH: /usr/lib/sdk/openjdk11/
    JAVA_AWT_LIBRARY: /usr/lib/sdk/openjdk11/jvm/openjdk-11/lib/libawt.so
    JAVA_JVM_LIBRARY: /app/jre/lib/server/libjvm.so
    JAVA_INCLUDE_PATH: /usr/lib/sdk/openjdk11/jvm/openjdk-11/include
    JAVA_INCLUDE_PATH2: /usr/lib/sdk/openjdk11/jvm/openjdk-11/include/linux
    JAVA_AWT_INCLUDE_PATH: /app/jre/lib

Now it is only complaining about 3 env variables:

Could NOT find JNI (missing: JAVA_INCLUDE_PATH JAVA_INCLUDE_PATH2 JAVA_AWT_INCLUDE_PATH)

Perhaps all is solved by setting:

build-options:
  env:
    JAVA_HOME: /usr/lib/sdk/openjdk11/jvm/openjdk-11/

Yes JNI is shipped as part of this extension.

The extension also ships a "enable.sh" script to set up your environment if needed.

Sourcing it will set up your JAVA_HOME and PATH variables appropriately. E.g. you should be able to do:

source /usr/lib/sdk/openjdk11/enable.sh && my_build_command

Hope that helps
