Install PPStream on 64bit Ubuntu…

PPStream is one of the biggest online TV in China. Now PPStream release a new client software on Linux. The first official release version is packaged as Ubuntu deb package and … only for 32bit system(x86).

As the Ubuntu on my laptop is 64bit release and has be updated to 10.10, install such a 32 bit software is a god damn tough job.

As we know that to install a 32bit software on 64bit OS, the first step is to install 32bit libs :
sudo apt-get install ia32-libs
and force to install without considering the architecture problem:
sudo dpkg -i --force-architecture somename.deb
Then if there is still some missing “lib” problem, use tool “getlibs” to solve:
getlibs -i somelib
And at the most of time, this problem has been solved at this step and we are happy to run the god damn 32bit on our OS.

But thanks to my upgraded Ubuntu 10.10, the tool “getlibs” didn’t work this time. And I tried to copy the missing libs for /usr/lib/ to /usr/lib32/ , only turn out a classical error message:

Library error: wrong ELF class: ELFCLASS64

Familiar? Yup, of course. This message is very common when you do some coding. It tells us that this library is not suitable. The reason is that those file I copied from is 64bit base software and their lib is also not suitable for 32bit software to use.

OK, it’s so suck that I can’t install 32bit lib just by typing apt-get command to fetched. And the stupid time started…

I went to http://packages.ubuntu.com/ to search those packages which contain lib file I needed. Then found the 32bit version to download.
Due to the suck architecture difference, we can’t install those package directly of course. Then how to move the lib file to /usr/lib32?

Use this command:
sudo dpkg -x somepackage.deb

“man” the dpkg command you will found

-x, –extract archive directory
Extract the files contained by package.

This command just extracted to deb file and didn’t do anything after all.
Then you know how to do next:
sudo cp lib*.so.* /usr/lib32
OK, we fixed one lib already. But my nightmare didn’t stop, because the god damn PPStream needs lots of extra libs to run.

Finally, the god damn thing works and I can have a little TV time before went to bed…

As a Linux user for several years, Linux give me another view of the world and lots of Linux lovers share lots of fun with me. Wanna to give thans to Linux, I bought a few stuff from a B2C web site.
The first one is a Tee with Ubuntu Logo:

It’s so awesome. Ubuntu is my using Linux dist.. And I love its logo because it show love and peace to us, Reminding us that we are connected , no matter where we are and whom we are.

The other Tee I bought is a GNOME Tee:

I love this “big paw” very much. GNOME is my favorite Linux Desktop environment. It’s so elegant and effective. There is no more luxuriant decorative odds in Gnome. That make it very friendly to me.

Beside those two Tees above, I also got a mouse pad in Ubuntu theme with half price~~

Do you Love it too ?

Let’s merge our OSs ~ VirtualBox

How many OS do you run simultaneously ? Only one Windows OS? Maybe, but why can’t we set up two, three or more OS at the same time! Maybe if we mention virtualizer software, you will think of Vmware, Virtual tool and so on. But what I want to introduce is the Virtual Box. VirtualBox is a general-purpose full virtualizer for x86 hardware. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software. The first time I use it was when I was searching software in Ubuntu. Before that I had used Vmware several times. To me, Virtual Box is more simple and comfortable. For an example, the seamless mode will make you desktop so cool ~. Can you imagine that Windows from Linux and Windows XP appear within the some desktop? Or run two or three online games which could not run on one physical machine before ? That’s so fantastic ! All you have to do is to download the Virtual Box software(if you are using Ubuntu , you can install via apt )and install whatever OS you want~ (使用教程请点此处)

Ubuntu is an African word meaning ‘Humanity to others’, or ‘I am what I
am because of who we all are’. The Ubuntu distribution brings the
spirit of Ubuntu to the software world.

Ubuntu 8.10 will be released at the end of October. And I am a Ubuntu user for almost two years now. Thanks to Ubuntu for giving us so fantasy experience of Linux.

Though I am not preparing to upgrade my Ubuntu 8.04 to 8.10. But I will put an eye on it. Hope Ubuntu will go further and further in the future.
As Mark said, Let’s fix the first bug that MS take the most park of OS market share.
