HOWTO: Compiling TUN/TAP Driver for HTC Hero

[Guest pupadi]

Setting up Android Development Environment ->

* Download HTC Kernel Source 2.6.29 from HTC Developere Site (hero-2.6.29-5f74b252.tar.gz)

* Download Android NDK from Android Developer Site (android-ndk-r4-linux-x86.zip)

* Download Android SDK from Android Developer Site (android-sdk_r06-linux_86.tgz)

* Extract the Kernel Source and Android NDK/SDK to a folder (say android) in home directory.

Preparing for Compiling TUN/TAP Driver ->

* Copy the confing file from the HTC Hero Device-

adb pull /proc/config.gz .

gunzip config.gz

mv config .config

* Copy the config file .config file to the kernel root folder -

cp .config ~/android/hero-2.6.29-5f74b252/

* CD to kernel source folder -

cd ~/android/hero-2.6.29-5f74b252/

gedit .config

* Edit the .config file to include tun.ko as module -

# CONFIG_TUN in not included

to

CONFIG_TUN=m

* Launch adb shell from the Android SDK folder and run uname -

cd ~/android/android-sdk-linux_86/tools

./adb shell

# uname -a

Linux localhost 2.6.29-063c4d24 #1 PREEMPT Thu May 27 00:21:28 CST 2010 armv6l GNU/Linux

* CD to kernel source folder and edit the Makefile -

cd ~/android/hero-2.6.29-5f74b252/

gedit Makefile

* Modify the following line to correspond with the kernel version -

EXTRAVERSION =

to

EXTRAVERSION = -063c4d24

* Set Environment Variables -

export ARCH=arm

export CROSS_COMPILE=arm-eabi-

export PATH=$PATH:~/android/android-ndk-r4/build/prebuilt/linux-x86/arm-eabi-4.4.0/bin/

* Now, make sure you can run arm-eabi-gcc from your Command Line * Perform make modules from the kernel source folder -

cd ~/android/hero-2.6.29-5f74b252/

make modules

* That's all, you should be able to find the tun.ko under ~/android/hero-2.6.29-5f74b252/drivers/net/
