Bug ID: 12751
Summary: OpenJdk package installation issues on target
Product: buildroot
Version: 2020.02
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other

Target Milestone: ---

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:

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?

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!

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!

--- Comment #4 from Ameya <[email protected]> --- 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?

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
