2. Initializinga Build Environment
Attention: Demonstration is in Ubuntu 12.04(32bit).
2.1 Installingthe JDK
The
Sun JDK is no longer in Ubuntu's mainpackage repository. In order to download it, you need to add the appropriaterepository and indicate to the system which JDK should be used.
Inputthe following command in the Terminal:
$ sudo gedit /etc/apt/sources.list
Add:
$ deb http://us.archive.ubuntu.com/ubuntu/ hardy multiverse
Inputin terminal:
$ sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"
$ sudo apt-get update
$ sudo apt-get install sun-java6-jdk
2.2 Installingthe Android SDK
Downloadthe SDK from Web Browser:
http://developer.android.com/sdk/index.html
Choosethe
adt-bundle-linux-x86-20130219.zip.
Inputin the terminal:
$ sudo mkdir ~/sdk
Copythe
adt-bundle-linux-x86-20130219.zipto the
/root/sdk and extract the zip.
Enterthe folder
/root/sdk/adt-bundle-linux-x86-20130219/sdk/tools.
Doubleclick the script file
android.
It willshow the
Android SDK Manager. Choosethe package with ticks.
Thenclick the
Install XX packages buttonon the right. It will start download the required packages.
Afterthe installation, add the SDK tools to
PATHEnvironment Variable.
Inputin the terminal:
$ gedit/etc/profile
Inputin the “profile”
$ exportANDROID_SDK_PATH=/root/sdk/adt-bundle-linux-x86-20130219/sdk
$ export PATH=.:$ANDROID_SDK_PATH/platform-tools:$PATH
Saveand close the
profile.
Inputin the terminal:
$ source/etc/profile
2.2 Installingthe Eclipse
Withthe download of
adt-bundle-linux-x86-20130219.zip,we can find the
Eclipse in the
/root/sdk/adt-bundle-linux-x86-20130219/eclipse.
Doubleclick the
eclipse can run it.
2.2.1Installing the ADT online
AndroidDevelopment Tools (ADT) is a plugin for the Eclipse IDEthat is designed to give you a powerful, integrated environment in which tobuild Android applications.
ADTextends the capabilities of Eclipse to let you quickly set up new Androidprojects, create an application UI, add packages based on the
Android Framework API, debug yourapplications using the Android SDK tools, and even export signed (or unsigned).apk files in order to distribute your application.
Run theeclipse and click the
help>Install NewSoftware.
Then clickthe
Add button.
Input the Name
ADT.
Input the Location
https://dl-ssl.google.com/android/eclipse.
Click
OK. Then it will show the choice for installation.
Click
Select All and
Next.
2.2.2Installing the NDK
The NDKis a toolset that allows you to implement parts of your app using native-codelanguages such as C and C++. For certain types of apps, this can be helpful soyou can reuse existing code libraries written in these languages, but most appsdo not need the Android NDK.
Downloadthe NDK from Web Browser:
http://developer.android.com/sdk/ndk/index.html
Choosethe
android-ndk-r8e-linux-x86.tar.bz2.
Inputin the terminal:
$ sudo mkdir ~/ndk
Copythe
android-ndk-r8e-linux-x86.tar.bz2to the
/root/sdk and extract the zip.
Inputin the terminal:
$tar –xvf android-ndk-r8e-linux-x86.tar.bz2
Finally,add the NDK folder to
PATH EnvironmentVariable.
2.2.3 Installing the CDT
TheCDT Project provides a fully functional C and C++ Integrated DevelopmentEnvironment based on the Eclipse platform. Features include: support forproject creation and managed build for various toolchains, standard make build,source navigation, various source knowledge tools, such as type hierarchy, callgraph, include browser, macro definition browser, code editor with syntaxhighlighting, folding and hyperlink navigation, source code refactoring andcode generation, visual debugging tools, including memory, registers, anddisassembly viewers.
Theinstallation of CDT is the same as ADT.
But theLocation of CDT is:
http://download.eclipse.org/tools/cdt/releases/indigo
2.3Installing the Cross Compiling Environment
TheCPU X86 is using the CISC, while the ARM processor is RISO. Therefore, thecross compiling environment should be installed.
TheCodeSourcery is an good choice for the cross compiling. It can be download fromthe following website.
http://www.mentor.com/embedded-software/sourcery-tools/sourcery-codebench/editions/lite-edition/
Choosethe
ARM Processor GNU/Linux release.
It willneed your personal information. Finally, system will send you an Email with thedownload URL.
Click the
Download Sourcery CodeBench Lite 2012.09-64.
Choose the
IA32 GNU/Linux Installer.
Afterdownload, enter the folder in terminal and use the following command:
$ ln –s/lib/i386-linux-gnu/libc.so.6 /lib
$ dpkg-reconfigure dash
Choose
NO.
$ sh arm-2012.09-64-arm-none-linux-gnueabi.bin
Add theCodeSourvery to PATH.
Inputin the terminal:
$ gedit/etc/profile
Inputin the
profile.
$export PATH=.:$/root/CodeSourcery/Sourcery_CodeBench_Lite_for_ARM_GNU_LIinux/bin:$PATH
Saveand close the
profile.
Inputin the terminal:
$ source/etc/profile
3. Test thefirst cross compiling environment
Programa simple first.c file.
#include
int main()
{
printf(“Hello world\n”);
return 0;
}
Inputin the terminal:
$ arm-none-linux-gnueabi-gcc–static –o first first.c
$ adb push first /data/local
$ adb shell
$ cd /data/local
$ ./first
