only double posting because for some reason it doesnt show my real reply

edit: and it's another one of those infamous need 2 replies to show the next page bugs i have run into with almost every forum software

edit #2: ok apparently you must have the patches from http://tushar.lfsforum.org/files/JavaFromScratch/ otherwise the compile will die quite quickly after you start it. Now all I need to do is wait another couple hours to see if this works.

It seems that no one is having much luck with getting java or any other plugins to work on gentoo 1.4.

I am running gentoo 1.4 in a dual boot with Windows XP. I regularly go into a java-based chat room and find that I am completely unable to get into this with Mozilla, Konquereor or Opera. I am able to get in with the old version of netscape that ebuilds with gentoo.

I wish to run java applets and was wondering what was the best way to go about this. I am willing to be unprincipled and use precompiled binaries if necessary.

Has anyone had any luck with anything except netscape. I tried installing a binary version of netscape 7.0 but this simply crashed

Yes, my install works fine (in mozilla-1.1).
I used (and somewhat wrote/tweaked, I guess) the ebuild posted earlier in this thread.

I've seen a lot of people saying that it (the ebuild) doesn't work for them, but little information that might be helpful in figuring out what might be going wrong. (There were, of course, probably a couple people who didn't feel it was necessary to pay attention to my "notes" section on the how to get it to work...)

I'm willing to tweak that ebuild more (so that at least some of the notes would not be required) but I'm more interested in getting some more people to have success with it first.

If anyone has tried it, or wants to try it, let me know exactly what problems you have, and I can try to help out.

Should this work also for mozilla 1.0.1? 1.1 is still too buggy for my tastes (try surfing around ebay for a little bit w/ 1.1 and you'll find out in short order when you "go back") so I'm trying to get Java working with that version instead.....I managed to get the ebuild to compile and install properly, and it works under konq (but not using the plugin, just pointing konq to the java executable), but mozilla, although it recognizes the plugin, crashes and burns whenever it hits a site with a java applet....

I'm also unable to get flash, arcroread, or realplayer to work properly either. Flash causes a crash and burn, as does acroread, and moz won't even recognize the realplayer plugin, so the problem may be bigger than just java. I tried rebuilding moz 1.01 with -gtk2 in my use to see if that helped to no avail....I'm beginning to start pulling my hair out....maybe I'll build the vanilla moz 1.0.

Ok, further testing reveals that the Java applet support works but it's very quirky... I don't think something is right. In Yahoo chat I can't type more than like 2 char without the entry box somehow losing the focus and needing another click to get back in in (every 2 chars it does this). Clicking the "Send" button does nothing, though hitting enter sends the message.

Dialogs and preferences and stuff SEEM to work, but lots of quirky happenings.

The ebuild now works for me (dumb me forgot step2 - as pointed out to me, I feel dumb now) - but Scott, you might want to remember that zip is a dependency for the sun-j2sdk - at least it failed the first time around for me because I didn't have that installed.

Also could expect be used to answer the overwrite question, so that this would require on interaction ?

My new Java 1.4.0 works beautifully in Konqueror, now to get Flash back on GCC3 (much harder, no source - and I don't want GCC2 stuff installed)

Thank you very much.

I managed to pull all the needed files off the two sites except i couldnt find

j2sdk-1_4_0-mozilla_headers-unix.zip

is this still on the java site? or is it no longer needed or something?

Okay, I got Java working using the shell script. Java applets are now working in Moz 1.0.1. In order to get flash and acrobat reader working I had to follow the instruction in this thread:

https://forums.gentoo.org/viewtopic.php?t=4753

Those instructions don't apply for plugins in Mozilla 1.1.

Now I still cannot get the native RealPlayer plugin to be even recognized by mozilla, and the Crossover plugins, while recognized, are not activated, and their mime types don't get registered in mozilla. Ideally, I would be able to have those plugins working as well.

Hey guys where do I download those file from sun webpage. Their site is so darn hard to get files and stuff ....

j2sdk-1_4_0-src-scsl.zip
- j2sdk-1_4_0-motif-linux-i386.zip
- j2sdk-1_4_0-mozilla_headers-unix.zip

Thanks for the ebuild, it worked flawlessly for me!

The inanity of Sun's website is a royal pain. I wish these companies wouldn't make us jump through so many hoops to get this stuff. Oh well, at least I lied on all my info during registration.

It's handy to remember the zip code for somewhere you USED to live when these sites try to "validate" your address

Oops, I guess I'm in violation of the license agreement. Like I care, especially after they made their website such a pain. They can try to find me

But on a more positive note, the ebuild works great!!! Thanks a lot.
Now, does anyone know why none of the commercial JVMs have started to support gcc3.2 in their binary releases? This makes little sense to me considering that it will soon be the standard for all distros and that at least one major distro (Mandrake?) already uses it.

Hi!

I'm having problems with my own compiled Java (I did it manually as described in the LFS article) and the Math.Pow method... perhaps you all want to have a look at my other post in Portage/Programming...

So I decided to build it again using the ebuild with less optimzations. The ebuild works fine. But: I wanted to compile using "-march=athlon-xp -O2 -pipe". Because I didn't know exactly whether the settings in make.conf are used, I changed the ebuild to use these flags (I directly added the flags to MY_CFLAGS and MY_CXXFLAGS). Everytime I had a look at the compilation, my march=... flag didn't show up, -O3 and a bunch of other flags were used... are my settings ignored? Doing it manually without the ebuild these settings were used... as far as I can remember. And the sad thing... Math.pow doesn't work with the fresh compile, too. Any ideas?

Okay, I spent some time editing the ebuild, but I haven't yet bothered to re-compile my system so I have no idea if it really works or not.
However, there are a couple of simple changes which can make things a little prettier:

1. Change the DEPEND to:

ok Scott, the -o thing works but the openmotif thing doesn't

Here's what it get's me.

/usr/sbin/ebuild.sh: line 95: local: `=': not a valid identifier
/usr/sbin/ebuild.sh: line 95: local: `openmotif-2.2.2-r1': not a valid identifier

Also, might we not also just be able to add the copying of the sun-jdk file in the ebuild?

I played a bit yesterday... obviously the jvm is built using fixed flags. I found them in the file gcc.make somewhere below src/hotspot/... There is no special optimization other than -O3 and no -march flag.
I tried to reduce -O3 to -O2, but therewith it doesn't finish the build... I don't know why. So, I tried adding -march=i686 as it obviously is considered to be stable. Therewith it compiled, but Math.pow again produced wrong results. BTW: If I run the class file compiled with my java using a different jvm (original sun), everything is fine, so only the jvm seems to be affected.

I really don't know what to do next... perhaps I have a look at the used patches...

Also, compile seems to fail on the unstable branch now, I'm guessing Java no likely gcc3.2-r2 or glibc 2.3.1

I went ahead and did some thing foolish

, I switsched to UNSTABLE- at this point everything seems to be working but......now java (my own compiled j2sdk) has bit the dust(reports something about relocation error!). I followed Tushars hints a while back and compiled my own j2sdk- it never worked with the mozilla 1.0-1.1 series, only with 1.2a/b did it work-(i mean the libjavaplugin-the rest worked fine). Now my libjavaplugin doesn't work anymore, again. So I decided to try to compile j2sdk again. I copied the ebuild script and shell script from the first page of this forum and tried both, to no avail...

For the life of me I cannot figure out where all the files go

I have downloaded all of the files(from sun and from tushar)
the ebuild script simply bombs giving a non-meaningful error. the shell script can't figure out where the patches are to be applied....
I trully appreciate the work that many here have offered, but I cannot figure out where I need to put what in order to get either the ebuild or the shell script to function....

I even tried stripping the shell script down to being nothing more than a list of exports- I named it 'build'

okram · Posted: Fri Oct 25, 2002 3:30 am Post subject: openmotif tip from tushar

Well, I keep having the same old problems and got a very nice tip from tushar: don't unmerge openmotif, just rename libXm.a to libXm.a.save, do your work and give it its original name back. That bit works, but for the rest there are still weird problems.
Weirdest of all is that I gave up on compiling my own java, returned to precompiled mozilla with precompiled java (sun-jdk-1.4.1) and the precompiled, binary plugin now only works if libXm.a is not around to mess things up (i.e. renamed). Any ideas why this should now affect precompiled binaries, too?

I wrote this script for compiling and installing java

http://tristan.halo43.com/files/gentoojava1.4.0.tar.bz2

just tar -xvjpf the file, and run install.sh as root.
the rest is done for you

i'd make an ebuild script if i knew how, but this works so eh.

After I ran your script I had to manually fix the mozilla plugin link to the java plugin .. and now Java works great in Mozilla .. thanks .. back to playing Java Euchre :-)

Yeah I had to do the samething and the weird thing is that the symlink was good even if the path to the plugin was wrong... anyways it works now yeah.

Alright. I opted to try this. After a few hours the compile fails with
