Building java

Building java

[Mike Looijmans]

Someone in our project decided he wanted Java on the board, so I just added 
"meta-java" to the layers and attempted to follow the README.

So without a clue as to what I'm really doing (I haven't touched Java in 15 
years) I added these to my local.conf:

# Headless java
PREFERRED_PROVIDER_classpath = "classpath-minimal"
# Possible provider: cacao-initial-native and jamvm-initial-native
PREFERRED_PROVIDER_virtual/java-initial-native = "cacao-initial-native"
# Possible provider: cacao-native and jamvm-native
PREFERRED_PROVIDER_virtual/java-native = "jamvm-native"

And of course added meta-java to bblayers.conf.

I added "openjdk-8" to the image's things to install, and let things build.

While building "openjdk-8-native", things went south, and I get the following 
error message:

ERROR: no configure script found at 
/home/mike/projects/.../build/tmp-glibc/work/x86_64-linux/openjdk-8-native/72b05-r0/jdk8u-e8bed1496ff2/configure


What did I do wrong?



(Note: the board does not have a display, so I don't need/want x11. I tried 
building openjdk-7 instead, but that fails to parse because it requires x11 in 
the distro)

meta-java is master, so you need poky on master, too - or cherry-pick the autotools.bbclass patch

You could port the remove-x11-patches to openjdk-7, since we currently need Java8, I have no "business case" to fix openjdk-7 :/

I was close to master already, but apparently not close enough.

Upgrading everything to current master results in:

ERROR: ParseError at 
/home/mike/projects/.../meta-oe/meta-oe/recipes-extended/sip/sip_4.16.4.bb:19: 
Could not inherit file classes/qmake2.bbclass

I don't care either, I'm happy when "helloworld.java" runs on target.

Current master is borked, it won't parse because about a dozen recipes need 
QT4 things that have been removed.

cherry-pick fe506edd from poky/master

Ran into too much trouble with oe-core, I'll wait until the dust has settled.

For now, I just added x11 to the DISTRO_FEATURES and built version 7 which 
runs okay on the board.

I'm puzzled by this message though:

NOTE: multiple providers are available for runtime java2-runtime (cacao, 
openjre-8, jamvm, openjdk-7-jre, openjdk-8)
NOTE: consider defining a PREFERRED_PROVIDER entry to match java2-runtime

To prevent picking another package, I tried adding:

PREFERRED_PROVIDER_java2-runtime = "openjdk-7-jre"

But that did not make the message go away.
