OpenJDK 7 Install
 

Hi all,
So I tried to compile OpenJDK 7 with the following:
I was then given the following error:
So I unset my $JAVA_HOME using the unset command. When I tried to compile again, I was given this error:

Where have I gone wrong. I have Googled this with no success. I have unset the environment variable as asked. Scratching my head a little now.

Regards,
Jack

This is the only person who has ever claimed to have succeeded in building OpenJDK on Slackware:

Hmm, that looks like its pretty hit and miss. Are there any binaries or SlackBuilds that you know of?

Thanks,
Jack.

I've nearly finished a SlackBuild for OpenJDK, and I don't want to put you off, but you're in for a few more challenges.

The primary documentation is here: http://hg.openjdk.java.net/jdk7/buil...ME-builds.html

You may also benefit from reading this: http://translate.googleusercontent.c...YFwrj8YIQRNyzQ [note that the translation process garbles the actual commands and output, so refer also to the original web page]

Your proximate problem is caused by not setting ALT_BOOTDIR. If you want solutions for your next three problems [1][2][3], try this:

... where LIBDIRSUFFIX has its conventional meaning. You'll need jaxp and jaxws sources in the current directory from http://download.java.net/jaxp/1.4.5/jaxp145_01.zip and
http://download.java.net/glassfish/c...2011_05_27.zip and
https://java.net/downloads/jax-ws/JD...2010_08_19.zip

[1] The build doesn't parallelize properly, see http://mail.openjdk.java.net/piperma...er/016062.html
[2] When README-builds.html says "NOTE: The Complete OpenJDK Source Bundles will contain the JAXP and JAX-WS sources", it's lying
[3] If you're running kernel 3.0 or 3.1, the build fails -- towards the end -- with "This OS is not supported"

I have packages for OpenJDK (a jdk and a jre package) which I created for Slackware-current. It took a while because I wanted OpenJDK to compile against the GCC java compiler after removing all traces of the Oracle java packages.

That "bootstrapping" of OpenJDK is quite complicated and it also required that I modified Slackware's gcc and seamonkey packages.
The reason for wanting to bootstrap the compilation is that I want to see if I can get OpenJDK built for ARMedslack. That does not yet have a JRE or JDK package at all (apart from "gcc-java").

I hope (once I re-built them from scratch to test the script and added a browser plugin for Java) that Pat Volkerding will accept all of this so that we can have a free JDK in Slackware (Oracle no longer allows for the new releases of their JDK and JRE to be bundled with distros).

Also, I have not even tried the packages to see if they actually work :-) I literally just finished compiling them. Today's post reminded me that I had a failed attempt at building OpenJDK sitting on my computer (I promised Pat early november that I would come up with a package to replace the Oracle stuff). And today I saw the flaw in my SlackBuild which prevented me from bootstrapping it against gnu java.

Great news Eric -- I'll use tomorrow for something else then :D

OpenJDK built for ARMedslack would be truly awesome, at least one model railway could use that straight away ;-)

I can confirm that the OpenJDK package works on my Slackware-current laptop - including the separate browser plugin package (icedtea-web) which I also created.
I have uploaded the sources and scripts to Pat Volkerding's server so he can have a look at the required changes to gcc and seamonkey.

Let's hope we'll see movement in slackware-current soon.

Eric

But, would it still be allowed for an end user to download the official Oracle binaries and install them by repackaging them using a local SlackBuild? eg: what we do for Google Chrome or Google Earth?

Is there room for a third-party developed SlackBuild (SBo, for instance) that simply downloads the official Oracle binaries and converts them into a Slackware package?

Will the OpenJDK be full compliant with the official Oracle java binaries? I ask this because I've happened to use OpenJDK browser plugin on an Ubuntu distribution some months ago, and some specific applet did not work correctly until I removed the OpenJDK packages and installed the official ones.

Of course. There will definitely be a Sun JDK7 SlackBuild on SBo.

If you want to have Sun JDK 7 *now*, btw, you can use Pat's Sun JDK6 SlackBuild to build it.

The slackbuild of OpenJDK is available somewhere?
If not it is possible to make it public?

Thanks for your effort :)

I have uploaded all sources, patches and scripts as well as 64bit packages to Pat Volkerding's server. I hope he approves those and adds them as updates to slackware-current soon.
Otherwise, if Pat does not show signs of activity, I will make all of that stuff public and create 32bit packages as well.

Eric

Thanks.

Is there any advantage or disadvantage on using OpenJDK instead of JDK?

I have no idea. My guess is that Oracle adds stuff to its own JDK which is not part of OpenJDK. The OpenJDK packages which I built are my first attempt and there are several variations in the choice of VM's and JIT compilers. I picked the defaults and it remains to be seen if that is the optimal choice. Also, the open source java webbbrowser plugin (icedtea-web) is not as good as the plugin which is included with the binary builds from Oracle. It will be a matter of choice and/or principle which version you choose to install.

The good thing is that this choice exists of course. I presume that Slackware will be shipping OpenJDK/JRE packages in future and http://slackbuilds.org/ would be a good place to provide a version of Slackware's current jdk.SlackBuild script which simply re-packages the Oracle binaries. It is absolutely allowed to download the Oracle binaries for private use. Oracle's binary license just no longer allows 3rd parties to re-distribute those. A shame, and illustrative of Oracle's view of the Open Source community and Free Software, but that's how it is.

Eric

Cool. Thanks for clarification!

Oh great. Thanks, I shall have a look on your site.

Hi I found out that the version of openJDK was a know bug (https://netbeans.org/bugzilla/show_bug.cgi?id=205348) that is resolved in newer version of openJDK.

Is it possible to build new packages with the new version?

Hi, sorry to open this topic again.
I have installed alien bob openJDK packages.
Until now it work very well, I mostly develop command line programs.

But when I run a graphical program, the graphic is broken as show in the image.

Is it a problem of the openJDK or mine?

I used 2 Java programs on a regular basis.

1. josm (Open Street Map editor)
2. psm (PlayStation Media Server)

Neither of those 2 applications show any issues with their displays, so if you want to test one of them out on your system and see if you have problems with them or not, to rule out your system setup.

I run several GUI applications which are programmed in Java, using web start or the browser plugin, and never had issues. It looks like yours is a local issue.

Eric

I have AlienBob's openJDK on several boxes and it works perfect so far.
One program I run gives an error about it not being tested on openJDK but it still runs perfect.
