 Posted: Fri Apr 06, 2007 2:21 pm Post subject: Some questions on AMD64 |
 |
|
Hi,
I'm installing gentoo on my brothers 64 bit dual core machine and I'm running into some issues.
Since I'm on x86 myself (athlon) I wasn't really conscious of some of the 32/64 bit problems before.
* Is it possible to have a java 1.5+ runtime plugin for 64 bit firefox? (No, blackdown 1.4 won't do) How? The various howtos I've browsed seem to be dated.
* Will I be able to use win32codecs on a 64 bit mplayer built from source?
* How about transgaming cedega for amd64. Any hints?
* Are there any more gotchas I should look out for?
TIA! |

For the Java runtime, look into nspluginwrapper, which lets you use 32-bit plugins in a 64-bit browser. Alternatively, try Konqueror, which interacts with Java directly without the aid of plugins.
You will not be able to use win32codecs, but you will be able to use win64codecs  In practice, I don't find much anymore that isn't natively supported by mplayer or xine anyway.
Haven't tried Cedega myself, but I'm under the impression it's not supported on amd64. Regular Wine works as well as it does on other platforms, though it has to be compiled as a 32-bit executable (ebuild takes care of this). |

Okay, I have the jre1.5.0.11 javaplugin in /opt/sun-jre-bin-1.5.0.11-i586/plugin/i386/ns7/libjavaplugin_oji.so
When I do /usr/lib/nspluginwrapper/x86_64/linux/npconfig -i on it I get
| Quote: | localhost ~ # /usr/lib/nspluginwrapper/x86_64/linux/npconfig -i /opt/sun-jre-bin-1.5.0.11-i586/plugin/i386/ns7/libjavaplugin_oji.so
nspluginwrapper: /opt/sun-jre-bin-1.5.0.11-i586/plugin/i386/ns7/libjavaplugin_oji.so is not a valid NPAPI plugin

What gives? |

Something is: look at that path. The ebuild is for 32-bit Java. |

well, i am @ ~amd64, now see here:
| Code: |
[ebuild N ] dev-java/sun-jre-bin-1.6.0-r1 USE="X alsa (-nsplugin)" 22,094 kB
[...]
http://distfiles.gentoo.org/distfiles/jdk-6-dlj-linux-amd64.bin
|
as you can see, this is a amd64 binary. why is nsplugin disabled (hardcoded) 
i dont think this is correct? |

Because SUN haven't released a 64 bit version of their Web Start (browser plugin) for the jre, as far as I can tell. |

well, if you look at the link i quoted above:
http://www.java.com/en/download/help/5000011400.xml
it looks like they did? and this is 1.5.0, hmm..
if so, nspluginwrapper is not needed, and the hardcodec "-nsplugin" should be removed from the amd64 profile.
well, maybe i miss something, but if the sun website tells it works using mozilla 1.5x.. hmm.. |

You're right, I remember reading about the Web Start on amd64 issue. Web Start != browser plug-in, rather, it lets you download and install Java applications from a remote repository. Essentially, it's a package manager for Java. And even on platforms where it exists (not amd64 linux) and where it works (not linux at all), it seldom knows what it's doing (windows). I seem to remember somewhere that you can just make a symbolic link from javaws to java and retain all the functionality without the UI, but that's not the issue here.
(EDITed for clarity.)
