F6ehp: /* A procedure for newbies to build their own Odroid system or to download ready to work images for -X or -U2 */

= How to install on U2 a custom built stable kernel =

Alas till today (2013, Jan 7) the official images for X2 and U2, as found on the HardKernel site, suffer from a fatal flaw that locks the whole system under heavy ethernet load.

Several users signaled the issue ( [http://odroid.foros-phpbb.com/t2086-u2-running-ubuntu-last-image-freezes-repeatedly-under-heavy-load see this thread] ).

The Hardkernel guys are actively investigating the problem; in the meanwhile a forum user (zehome) developed a patch of kernel config and provided on his web site a package for a new kernel that fixes the above problem.

The install procedure is as follows:

cd
wget http://odroid.zehome.com/odroidu2_ed_kernel_rel3.tar.gz
tar xzf odroidu2_ed_kernel_rel3.tar.gz
cd odroidu2_ed_kernel_rel3 && ./install.sh

sha1sum: b3e86718f69b9801097819a7250876cd0053b9cd odroidu2_ed_kernel_rel3.tar.gz
md5sum: ba0088cb23e0be5a11012cd4acf3c844 odroidu2_ed_kernel_rel3.tar.gz

= How to compile Qt5 =

In order to compile Qt5, is mandatory to start from a clean system, especially if you are using a 8 GB SD card.
Moreover, you have to install the mesa packages:

sudo apt-get install mesa-utils mesa-common-dev libgl1-mesa-dev x11proto-xext-dev libxrender-dev

missing this step, the build will fail on unknown OpenGL symbols, '''even if the OpenGL build has been explicitly disabled'''.

Append to ~/.bashrc the following lines:

export CPPFLAGS='-O2 -fPIC'
export CXXFLAGS='-O2 -fPIC'
export CFLAGS='-O2 -fPIC'

[https://bugs.launchpad.net/gcc-linaro/+bug/924726 See the bug #924726]

Clone the base repository:

cd
git clone git://gitorious.org/qt/qt5.git qt5

this is only a template repository, it is almost empty, we need to download the whole code using the initialization script

cd qt5
perl init-repository --no-webkit

Next we have to configure, avoiding to compile examples and test programs, in order to shorten the build time:

./configure -developer-build -opensource -nomake examples -nomake tests -no-pch -qt-xcb
'''make -j8'''

If the build ends successfully, there is no need to install the package, it is enough use includes and libraries as found in ~/qt5/qtbase directory.

export PATH=~/qt5/qtbase/bin:$PATH
