Hi,
I’m building an image from scratch and would like to include java. I just want to make sure that my configuration is fine.
I’m following Toradex tutorial.
But there is no information about 2.6 images , e.g :
repository version known to work with V2.5 images
META_JAVA=0d7ba0ff39a332b0f93c4958370b2c7db9ea0e30
So I´m including the latest from git repository:
META_JAVA=1d820a778c0aa5d1d8bbff9949e77c32a08c8a7b
Added java layer to build/conf/bblayers.conf :
${TOPDIR}/../stuff/meta-java \
Changed local.conf:
#OpenJDK Installation
PREFERRED_PROVIDER_virtual/java-initial = "cacao-initial"
PREFERRED_PROVIDER_virtual/java-native = "jamvm-native"
PREFERRED_PROVIDER_virtual/javac-native = "ecj-bootstrap-native"
IMAGE_INSTALL_append = "openjdk-8-jre \
jamvm \
But at meta-java page it’s suggested to use java-initial-native instead of java-initial
PREFERRED_PROVIDER_virtual/java-initial-native = “cacao-initial-native”
Which one is the right to use?
I saw elsewhere the following options to set. Is it necessary?
#For openjdk7:
PREFERRED_VERSION_openjdk-7-jre = "25b30-2.3.12"
PREFERRED_VERSION_icedtea7-native = "2.1.3"
#Sometimes the following is needed:
#PREFERRED_PROVIDER_openjdk-6-jre = "openjdk-6-jre"
#PREFERRED_PROVIDER_openjdk-7-jre = "openjdk-7-jre"
Regards!

Using sufix “-native”, this produces a recipe that only builds for the build host.
I have a model to use, but when I used was branch dizzy:
PREFERRED_PROVIDER_virtual/java-initial = "cacao-initial"
PREFERRED_PROVIDER_virtual/java-native = "jamvm-native"
PREFERRED_PROVIDER_virtual/javac-native = "ecj-bootstrap-native"
PREFERRED_VERSION_openjdk-7-jre = "25b30-2.3.12"
PREFERRED_VERSION_icetea7-native = "2.1.3"
–
IMAGE_INSTALL_append = "openjdk-7-jre"

Thanks Cleiton! I was using the same config as you but I’m trying to update java. Trying to find these “magic” numbers “25b30-2.3.12” or “2.1.3” for newer java versions.
With our current jethro branch I tested build of openjdk-8 using the master branch of meta-java and had a successful build.

But how to make it work with IMAGE_INSTALL_append ?
For Java, please follow the instruction here. However for META_JAVA use the below,
META_JAVA=33ddb28a6428b02ddcc82d1954ecf27cd426fbb5
In your ~oe-core/build/conf/local.conf add
IMAGE_INSTALL_append = " openjdk-8"
and then execute
MACHINE=apalis-imx6 bitbake angstrom-lxde-image
This should build an image with openjdk-8 support.
