[meta-java] OpneJDK nativesdk recipe

[meta-java] OpneJDK nativesdk recipe

[Akira Shibakawa]

Hi
I want to let my customer compile java code on Yocto SDK.
But, there is no nativesdk recipe of OpenJDK in meta-java.
Is there any reason to it ?
Or, is there any plan to add it ?

thanks

I guess no one submitted a patch to enhance the recipe to do nativesdk
builds so far.

It's Java - write once debug everywhere - so I guess the use case you 
want is not frequently needed.

A quick grep shows this:

bitbake-layers show-recipes | grep -B 1 meta-java | grep native
ant-contrib-native:
ant-native:
cacao-initial-native:
classpath-initial-native:
classpath-native:
ecj-bootstrap-native:
ecj-initial-native:
icedtea7-native:
jamvm-initial-native:
jikes-initial-native:
libecj-bootstrap-native:
openjdk-8-native:

meaning there is no nativesdk- recipe in meta-java

There are -native recipes like openjdk-8-native but they are only 
accessible to your customer in "cooker mode" after bitbaking everything.

something like:

bitbake openjdk-8-native -c addto_recipe_sysroot
oe-run-native openjdk-8-native <whatever you want to call from there>

As a workaround you could build an extensible SDK, write a recipe and 
let your customer compile like that.
