[gentoo-dev] Mozilla "patch" for flash/linux/GCC3.1

Hi,

I've not gotten around to learning how to create/modify ebuilds myself yet, so 
I'm submitting this here in the hope that some worthy sould will take this and 
run with it.

Problem:
If mozilla is built with GCC3.x then loading flash or java plugins causes it to 
crash. Bummer. This is bug 124006 in mozillas bug database.

Solution:
Write a small patch library to supply the reuired missing functions and preload 
it (e.g. LD_PRELOAD=libmozhack.so). The required code is attached to this, mail. 
See, it's really trivial, build it with "gcc -shared -fPIC -o libmozhack.so 
libmozhack.c && strip libmozhack.so"

So I suggest that a revision of the mozilla ebuild includes the following logic:

do-usual-stuff;
if (gcc-3-based-build) {
   copy mozhack.c from ebuild-files-dir to work-dir;
   build libmozhack.so
   copy libmozhack.so to /usr/lib/mozilla
   patch mozilla shell script to preload libmozhack.so
}

What do people think?

Ian.

jdk/jre as such works well with gentoo-1.3/gcc-3.1 (I use 
blackdown-jdk-1.3.1-r7 - the latest as of this point of time) but Mozilla 
again seems to be having some problems with the java plugin provided by 
blackdown. The plugin doesn't get "registered" (doesn't show up on 
entering about:plugins). I tried remerging blackdown-jdk and 
setting java-config --set-system-vm=blackdown-jdk-1.3.1 to no avail. I am 
still trying. Perhaps this is a problem with blackdown and not gentoo-1.3?

Alrighty.. 

Will this fix this issue for all browsers out there?
I mean Mozilla/konqueror/galeon/.... ?
I don't want a half solution on this.

On another note, karltk, how's java support for gentoo 1.3?
Is there a working java jre/jdk for use with gcc 3.1?

See ya & Thanks!

I'm using sun-jdk-1.4.0 without any problems.

Starting mozilla in the console gives me this (plugin doesn't work obviously):

cxvx@luke cxvx $ mozilla
LoadPlugin: failed to initialize shared library 
/opt/sun-jdk-1.4.0/jre/plugin/i386/ns610/libjavaplugin_oji.so 
[/opt/sun-jdk-1.4.0/jre/plugin/i386/ns610/libjavaplugin_oji.so: undefined

Unless you want to go through JNI, it works nicely. If you do, you will
need to use kaffe.

The browser plugins do not work, nor will they until the up-stream
commercial vendors recompile their binary JDKs.

I just tried it for galeon on my gcc3.1 box. It fixes the same problem
perfectly. Definitely worth putting into portage IMO.

Yeah, but galeon uses mozilla... i meant systems _without_ mozilla, 
and only konqueror (like mine).. How could this be fixed then?
Can't we just let the flash ebuild install the workaround as well?
