Convert from Debian/Ubuntu to Gentoo
Recently after having doubts and confusions after all I made my switch to Gentoo. Previously I was using Ubuntu/Debian on my laptop. I still have to learn a lot. Gentoo’s awesome wiki helps me a lot, particularly TIP_Converting_from_or_to_Debian very much.
How to embedd Linux Applications
Are you a software vendor looking for embedded linux appliances for your softwares? Or just another geek to see how embedded linux operates? Well, here’s your chance to try it out!
FOX Board, a complete Linux system in just 66 x 72 mm
FOX Board runs a real Linux operating system (not a uC Linux) on an ETRAX 100LX microprocessor, a 100MIPS RISC CPU made by Axis.
FOX Board has two main field applications:
- As a stand alone device to build a micro web server or other network devices as proxy, router, firewall, etc.
- As a core engine to plug onto the PCB of a user application board instead of a simple microcontroller.
Two USB 1.1 host interfaces can be connected to USB memory stick, hard disk, webcam, modem, Wi-Fi or Bluetooth dongle, ADSL adapter, Serial converter, etc.
Through the 10/100 ethernet interface it is possible to have access to the internal Web server, FTP server, SSH, Telnetd and the complete TCP/IP stack.
Hardware Features
Size: 66 x 72 mm (2.6 x 2.8 inches)
Weight : 37 gr
Cpu: Axis ETRAX 100LX 32 bit, RISC, 100MHz (100MIPS)
Memory: FOXLX816: 8MB FLASH 16MB RAM FOXLX832: 8MB FLASH 32MB RAM
Power: Single power supply 5 Volt 280mA (1 watt)
Ports: 1 Ethernet (10/100 Mb/s), 2 USB 1.1, 1 serial console port
Extension: 2 extension sockets with IDE, SCSI, serial lines, parallel ports, I/O lines, I2C bus interface
Temperature range: 0-70 °C
KDEV developed SMS FoxBox - SMS Gateway Solution with this board and Linux embedded inside.
Acme Systems provides various kinds of APIs and documentations on how to do things with the boards, which I find very useful indeed. This item is already in my must have list!
How to switch between gcc versions and install QEMU
I recently migrated my laptop to Gentoo Linux. I think it will serve me well as in introduction to inside of Linux and explore how things operate and build in there. But sometimes I have to work in Windows, for that I used QEMU.
It’s a great tool, however it needs to be compiled with gcc 3 while in the recent Gentoo Linux it comes with gcc-4.1.2.
So, first install gcc 3, type:
emerge =sys-devel/gcc-3.4.6* -av
You can take a look at your gcc config file and see your correct gcc 3 version and architecture in /etc/env.d/gcc folder
My laptop has i686-pc-linux-gnu-3.4.6 So I type:
gcc-config i686-pc-linux-gnu-3.4.6
Then update my profile:
source /etc/profile
Now, you might need to unmask these stuff, type in:
echo “app-emulation/qemu” >> /etc/portage/package.keywords
echo “app-emulation/qemu-user” >> /etc/portage/package.keywords
echo “app-emulation/qemu-softmmu” >> /etc/portage/package.keywords
echo “app-emulation/kqemu” >> /etc/portage/package.keywords
echo “>=app-emulation/qemu-0.8.2″ >> /etc/portage/package.mask
echo “>=app-emulation/qemu-user-0.8.2″ >> /etc/portage/package.mask
echo “>=app-emulation/qemu-softmmu-0.8.2″ >> /etc/portage/package.mask
If you want graphical output, enter the following in /etc/portage/package.use
app-emulation/qemu-softmmu sdl
So when you are ready, install QEMU by typing:
emerge qemu -av
QEMU is also helpful for Windows users to get to know Linux without really installing it on their PCs. It will run Linux inside your Windows. It gives you a chance to use Linux before migrating.

As in life, in computers we throw away all the unwanted files, softwares and sometimes partitions, but there are times when we think it wasn’t unwanted things at all. Later when we remember, we regret we had thrown them to the recycle bin, have emptied it afterwards.
