就是 kubuntu 中的 kopete 不支持 gtalk 的语音对话功能。。。
是个很遗憾的事情，但原因呢？
下面来看看 #kubuntu-devel 里的开发者是怎样回答的吧~

[21:14] <_StefanS_> Tonio_: since the last version, I cant configure my mouse anymore. It complains about it cant create the input device
[21:17] <nihui> Riddell: Tonio_: Why doesn't the gtalk in kopete have "voice call" function?
[21:17] <Tonio_> _StefanS_: hu ?
[21:17] <nihui> may i have the reason please?
[21:17] <Tonio_> nihui: we don't build it with libjingle I guess....
[21:17] <_StefanS_> Tonio_: I can see my bt mouse, but clicking the "setup" button yields a dialog with the message that It can create the inpu tdevice
[21:18] <Tonio_> _StefanS_: need to test that toonight, no bt mouse here
[21:18] <_StefanS_> oka
[21:18] <Tonio_> nixternal: what is the malone status for "rejected" now ? is that "won't fix" or "invalid" ?
[21:19] <nihui> Tonio_: but why don't you built it with that? i think the "voice call" is really great~
[21:20] <freeflying> Tonio_: won't fix and invalid
[21:20] <Tonio_> freeflying: both ? oki
[21:20] --> viviersf 已经加入此频道 (n=cain@gw.impilinux.co.za)。
[21:20] <Tonio_> nihui: because the lib is in universe, and we try not to get too much lib in main
[21:22] <Tonio_> nihui: btw a "main" package cannot build-depend on a universe one
[21:22] <Tonio_> nihui: too late in the gutsy dev cycle to get that done, but we may consider this for gutsy+1 then
[21:22] <freeflying> Tonio_: both
[21:23] <Hobbsee> nihui: ahh, i know the answer to this.
[21:23] <Tonio_> Hobbsee: ah ? :)
[21:23] <nihui> Hobbsee: ?
[21:23] <Tonio_> nihui: also the voice support in kopete isn't really stable atm
[21:23] <Hobbsee> nihui: because gtalk only works with a particular version of libjingle, and we have a later version in ubuntu, which other things depend on.
[21:24] <Hobbsee> tha'ts the main reason that i havent put it in.
[21:24] <Hobbsee> and getting an obsolete vesrion of a library in main....even the thought of that is painful.
[21:24] <freeflying> Hobbsee: nihui wonders why other distribution supports :)
[21:24] <Tonio_> Hobbsee: interesting
[21:25] <Tonio_> Hobbsee: so the libjingle version we have is incompatible with gtalk ?
[21:25] <Hobbsee> freeflying: because it's not commercial support, and they dont care about having multiple libraries.
[21:25] <Hobbsee> Tonio_: it was when i last checked (when it was first announced), yes
[21:25] <Tonio_> Hobbsee: okay
[21:25] <manchicken> Anybody ever got a webcam working in kubuntu before?
[21:26] <Tonio_> nihui: also according to kopete devs, they will not have a nice and stable gtalk support before kde4/phonon
[21:26] <freeflying> manchicken: webcam is not spcific to kubuntu
[21:26] <Tonio_> Hobbsee: looks like phonon is meant to support jingle, I didn't knew that
[21:26] <manchicken> freeflying: This I know. But system76 claims this guy works under gnome, and I'm having a hard time configuring it in kubuntu.
[21:26] <freeflying> Tonio_: how dose phonon support jingle?
[21:27] <Tonio_> freeflying: no idea that was on the blog of a kopete dev
[21:27] <manchicken> Hmm...
[21:27] <Tonio_> freeflying: he was explaining that the jingle support within libjingle is a bit crackfull, and that this would change with kde4/phonon
[21:28] <freeflying> manchicken: borrow me one, I will configure it for you :)
[21:28] <freeflying> Tonio_: sounds niceTonio_：首先，编译 kopete 的 gtalk 的 voice call 支持，必须依赖 libjingle 这个库的编译。
而 kubuntu 的 kopete 并没有依赖这个库，所以就没有语音功能了。
libjingle 这个库是 universe 的，而开发者并不想引入过多的额外库依赖。
一个 "main" 软件包不能依赖于一个 universe 软件包编译。
kubuntu 7.10 gutsy 的开发周期已经不允许那么大的变动工作了，不过可能 gusty 之后会纳入这个功能支持。
Hobbsee：gtalk 只能在一个特定版本的 libjingle 下运作，而我们在 ubuntu 中只有比较新的版本，其他软件包需要依赖新版本的库。
在 Hobbsee 最新一次核实的时候确认了，当前已有的 libjingle 版本和 gtalk 所需的是冲突的，无法使用。
其他发行版之所以可以有 voice call 功能是因为它们不是商业支持，所以它们不用关心多版本库的重叠。
Tonio_：在 kde4/phonon 之前的 gtalk 支持不是很好且不太稳定。
好了，原因很清楚了：编译语音支持需要一个陈旧版本的 libjingle，而当前是新的。同时使用多个版本可以达到目的，但是商业支持不允许这么做。
