We have learned a little about running this software, its installation and how to run it. Today we are going to execute a virtual machine and some programs.
What is the best way to install an application in Debian?... Exactly!, through apt-get:
sudo apt-get update
In the screenshot above we can clearly see how the system is updating from 386 repositories. Not all commands are supported, for example, you can not use apt-get dist-upgrade.
As I said, both host and guest, shared user folder, and you can copy files from one machine to another.
In Raspbian, the best is modifying the file /etc/apt/sources.list that comes on the guest system, so you will have a broader catalog and updated software for testing :
deb http://ftp.fr.debian.org/debian/ wheezy non-free contrib main deb http://ftp.fr.debian.org/debian/ wheezy-updates main contrib non-free deb http://ftp.fr.debian.org/debian/ wheezy-backports main contrib non-free deb http://security.debian.org/ wheezy/updates main contrib non-free deb http://www.deb-multimedia.org/ wheezy main non-free deb http://www.deb-multimedia.org/ wheezy-backports main
On ODROID boards, I'm going to install an application using PPA that I use in my daily life: The file manager Double Commander:
sudo add-apt-repository ppa:alexx2000/doublecmd -y && sudo apt-get update && sudo apt-get install -y doublecmd-gtk
Fantastic!. The program behaves as it should, and now I can manage all my file operations with this Total Commander's clone. It have been easy, haven't it?, How about trying a game?. In this case, I opted for one that you can find in the official repository: Armagetron Advanced.
sudo apt-get install -y armagetronad
The game has not recognized me the GPU in ODROID, perhaps due to a conflict and only reach 6 fps. On Raspberry Pi 2, I get a black screen and does not start, as you can see in the capture.
I'll try VideoLan:
sudo apt-get install -y vlc
After a while installing dependencies, and execute on both boards where I've tested (ODROID-C1 and Raspberry Pi 2), the display is shown in black when I play a .mp4 file. I have tried several video codec, but none of the supported work. Anyway, I had to try.
Since I'm a person with habits, my development tool is Sublime Text. Let's try to install & run:
wget http://c758482.r82.cf2.rackcdn.com/Sublime%20Text%202.0.2.tar.bz2 tar xvf Sublime\ Text\ 2.0.2.tar.bz2 ./sublime_text
It works flawlessly, which is appreciated if you are a developer.
Let's do the real test and that surely will be willing to try: I'm going to test Wine. As you all know, Wine (Wine Is Not an Emulator) allows the execution of programs to almost all versions of Microsoft Windows under Linux.
On ODROID: sudo add-apt-repository ppa:ubuntu-wine/ppa -y && sudo apt-get update && sudo apt-get install wine1.7 winetricks -y On Raspberry Pi (Older version): sudo apt-get install wine winetricks -y
After installing a few dependencies. The first thing that occurred to me to install is a SNES emulator called zsnes, which has always been and will be my favorite.
The result, it works almost perfectly. It is playable, but I can not put the emulator in full screen.
I dont test much apps, only a few works. I guess my failures with wine are mainly due to each application requires a series of internal settings (native dll, optional parameters, ..), and there are some applications under Wine that does not work, such as Media Player HC, Internet Explorer 8/9, iTunes 10... My advice is that if you need to run a particular software, make sure it works on your PC with Linux before.
Ill try more apps and expand this section in a future.
Exagear Desktop does what it promises: Run x86 Linux applications on ARMv7 processors. When you see that an application works with another architecture on your board, it looks like magic. It's common to run emulators of other machines and older consoles in this kind of systems. The same is done here. A curious fact is that I thought the processor would be 100% loaded whenever running a virtualized application, and barely reached 60% load. After spending several days trying it, I can draw the following conclusions:
If you have an application that you use on your PC and you don't want/know to compile it, or It is not available, this is the ideal solution.
Faster than other solutions on the market.
Very easy to install and use.
Almost all software I find, can be compiled natively on your board.
I hope you have a good Micro SD card and that contains at least 16 GB.
Don't you expect miracles or run PC games requiring 3D.
Obviously, in the Raspberry Pi 1, does not go as smooth as the Pi 2. I notice that, with a ODROID-C1, all the job is done smoother and faster, it perhaps due a more powerful CPU. Perhaps with the ODROID U3, we can't notice the difference between a native application or another virtualized.
That's all, folks. I'd like to make a video so you can see the load times or other aspects that may interest you more than me, but I could not because of time, but it's pending.
If you want to express your impressions or you want that I try some software in particular, use the comments below.
I hope it helps you.
