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:

http://martinusadyh.web.id/2011/05/2...-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

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.

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.

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.

Cool. Thanks for clarification!

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