           Summary: OpenJdk package installation issues on target
           Product: buildroot
           Version: 2020.02
          Hardware: All
                OS: Linux
            Status: NEW

Hi,

The current openjdk package INSTALL_TARGET_CMD installs only the lib and bin
folder to /usr/lib

the JRE/lib folder contains a modules file which in conflict with modules
directory which has kernel modules

i am doing a x86_64 build , the lib is symlinked to /usr/lib on target and all
kernel modules get installed /lib/modules

Sometimes the overwrite works during copy and kernel modules get replaced by
java modules file

cp -dpfr $(@D)/build/linux-*-release/images/jre/lib/* $(TARGET_DIR)/usr/lib/

Here is the error i have gotten:

>>> openjdk 13.0.2+8 Installing to target
cp -dpfr
/bulk/ajoshi2/nuc-build/build/openjdk-13.0.2+8/build/linux-*-release/images/jre/bin/*
/bulk/ajoshi2/nuc-build/target/usr/bin/
cp -dpfr
/bulk/ajoshi2/nuc-build/build/openjdk-13.0.2+8/build/linux-*-release/images/jre/lib/*
/bulk/ajoshi2/nuc-build/target/usr/lib/
cp: cannot overwrite directory ?/bulk/ajoshi2/nuc-build/target/usr/lib/modules?
with non-directory

Can we update the INSTALL_TARGET_CMDS for openjdk to install the entire JDK
inside /usr/lib/jvm folder and symlink the binaries?

I had "symlink" option selected inside "system configuration" page or maybe the 

pc_x86_64_bios_defconfig has that selected by default.

Unchecking it should solve the buildroot error 

But in our case , i do need the entire JDK on the system ,  and not just the
libs and bin?

can we have a option created in menuconfig to select that?

Hello Ameya!

Sorry for the delay, I will take a look at this today!
If you need the entire JDK I will create the changes necessary to do so.

Thanks again!

Adam

Hello Ameya;

I have created a patch series that should fix your issues.
In addition, I also submitted a patch that will allow building and installing
the full JDK.

If you would be so kind as to test the patches and possibly provide a
"Tested-By" comment if they work for you, I would very much appreciate it.

Fixes for 2020.02.x:
https://patchwork.ozlabs.org/project/buildroot/list/?series=171015

Fixes and JDK support for master:
https://patchwork.ozlabs.org/project/buildroot/list/?series=171014

Thanks!

Adam

Hi Adam,

I get error while applying the patch 

https://patchwork.ozlabs.org/project/buildroot/patch/20200417232922.3762195-4-aduskett at gmail.com/


Also i looked at the patch it replaces the existing build and install commands 
so if a user doesnt want a full JDK it wont work right?

Regards,
Ameya

Hi Ameya;

This patchset does two things:

1) It fixes the originally reported bug.
2) It adds a menu config item that allows you to select if you want to build
the full jdk instead of just the JRE.

If you do not select the option to build the full JDK then the JRE will be
built instead.


If you want the ability to install the full JDK on 2020.02, you will have to
apply all 4 patches to master and then backport the changes yourself to
package/openjdk on 2020.02.

Thanks!

Adam
