First of all, you need to have a recent Linux distribution, Fedora 20/21, Ubuntu 14.04, ARCH Linux, SuSE Linux) and at least 15 GB of free space.
The heart of the OpenELEC project is our software build system. It supports a software building technique called cross-compiling; the process of creating executable code that runs on one hardware platform from something other than that platform. Cross compiling is a crucial function for the OpenELEC project for the following reasons:
Start by updating your system (on Ubuntu or other Debian-based distribution):
Note: Debian does not need "sudo" however the commands are identical once sudo is removed.
Note: at least gcc-4.7 is required.
sudo apt-get update sudo apt-get upgrade sudo apt-get install make
Reconfigure to bash so we have best possible script compatibility
sudo dpkg-reconfigure dash
and select no, to install bash as the default
Then, install build tools
you will need libxml-parser-perl
sudo apt-get install libxml-parser-perl
yum install autoconf automake binutils cpp cvs gcc gcc-c++ glibc-devel glibc-headers glibc-static kernel-devel kernel-headers libmpc libstdc++-devel libstdc++-static ncurses-devel perl-libintl perl-Test-Harness perl-Text-Unidecode perl-Thread-Queue texinfo
git clone https://github.com/OpenELEC/OpenELEC.tv.git
A new folder called OpenELEC.tv will be created.
Be sure to have lot of free space - at least 15 GB. Better more than less.
In a terminal go to the folder that was just created.
Option 1: To build a bootable disk and update image for 64bit computer with AMD or modern Nvidia cards that are not listed here http://www.nvidia.com/object/IO_32667.html
PROJECT=Generic ARCH=x86_64 make image
Option 2: To build a bootable disk and update image for 64bit computer with old Nvidia GPU that are listed under secion 304.xx and few newer ones here http://www.nvidia.com/object/IO_32667.html
PROJECT=Nvidia_Legacy ARCH=x86_64 make image
Option 3: To build a bootable disk and update image for raspberry pi/zero:
PROJECT=RPi ARCH=arm make image
Option 4: To build a bootable disk and update image for raspberry pi2/pi3:
PROJECT=RPi2 ARCH=arm make image
Option 5: To build a bootable disk and update image for WeTek Play:
PROJECT=WeTek_Play ARCH=arm make image
PROJECT=imx6 ARCH=arm make image
Take a break after hitting return.
When the build completes, you will find the fresh build in the target directory of your build directory OpenELEC.tv/target/
If you need to clean and start over do a
make clean and then start the build process again.
