Codesourcery toolchain
From OK6410 wiki
Codesourcery Lite G++ ARM toolchain
Go to the following website:
http://www.codesourcery.com/sgpp/lite/arm/
And download the Linux installer of the GNU/Linux version. (I used arm-2010q1-202-arm-none-linux-gnueabi.bin)
IMPORTANT: If you want to build U-boot as well using the Codesourcery toolchain, you need to download the (older) 2010q1-202 version because otherwise U-boot will not find the RAM memory of the OK6410 Board and the kernel can't be loaded. You can see it on the bootscreen of U-boot if the RAM is properly loaded.
After downloading the package open a terminal and go to the directory where the file is saved and type:
$ chmod a+x arm-2010.......bin $ sudo ./arm-2010.........bin
64-bit Linux users must make a few changes to their system. You can read them here on the Codesourcery website!
If you get an error message in the terminal, type:
$ sudo dpkg-reconfigure -plow dash
And in the window that appears, choose No, and rerun the ./arm-2010.....bin command.
During the installation select the following options:
- Typical installation
- Install directory, change to: /usr/local/Codesourcery....
- Do not Modify PATH
- Binary Directory, change to: usr/local/Codesourcery....
After the installation is complete you need to add the new location to your PATH. In your home directory type:
$ gedit .bashrc
Add the bottom of the file add the following line:
export PATH=$PATH:/usr/local/CodeSourcery/Sourcery_G++_Lite/bin/
Reload your path by using the command (the command is WITH the dot and space!):
$ . .bashrc
Then you can try if the ARM toolchain works by typing:
$ arm-none-linux-gnueabi-gcc -v
Which results in

And on the last line you can read the used GCC version for the cross-compiler
