This article mainly introduces how Ubuntu14.04 cross-compiles busybox to the ARM target board of Android system. The article is very detailed and has certain reference value. Interested friends must read it!

Get a RK3288 development board, but I have to say that adb shell is not very easy to use, like the following is too filthy.

So I wanted to compile busybox into it.

1. Prepare the compilation environment

In fact, cross-compilation on Ubuntu is much easier now than it was before.

1.1 install the JDK 6:sudo add-apt-repository ppa:webupd8team/javasudo apt-get updatesudo apt-get install oracle-java6-installer1.2 dependency package:

Ubuntu 12.04 package installation:

Sudo apt-get install git gnupg flex bison gperf build-essential\ zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev\ libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386\ g++-multilib mingw32 tofrodos gcc-multilib ia32-libs\ python-markdown libxml2-utils xsltproc zlib1g-dev:i386

Installation of the Ubuntu 13.10 Lex14.04 package:

Sudo apt-get install git-core gnupg flex bison gperf libsdl1.2-dev\ libesd0-dev libwxgtk2.8-dev squashfs-tools build-essential zip curl\ libncurses5-dev zlib1g-dev pngcrush schedtool libxml2 libxml2-utils\ xsltproc lzop libc6-dev schedtool g++-multilib lib32z1-dev lib32ncurses5-dev\ lib32readline-gplv2-dev gcc-multilib libswitch-perl1.3 install the ARM cross-compilation tool chain and compile kernel-related software packages: sudo apt-get install gcc-arm-linux-gnueabihf\ lzop libncurses5-dev\ libssl1.0.0 libssl-dev

As for gcc-arm-linux-gnueabihf or gcc-arm-linux-gnueabi, it depends on your chip. It should be hard float.

2.busybox source code

Download the latest version of busybox source code at http://www.busybox.net/downloads/.

$mkdir ~ / busybox # create a working directory $cp busybox-1.22.1.tar.bz2 ~ / busybox # copy the source package $cd ~ / busybox/ # enter the working directory $tar-jxvf busybox-1.22.1.tar.bz2 # extract $cd busybox-1.22.1/ # into package 3. Compile ready 3.1 environment variable dpkg-L gcc-arm-linux-gnueabihf

See where the installation, apt-get installation is good, generally / usr/bin, no need to add to the environment variable

3.2.Create the installation folder mkdir busybox-install4. Meke menuconfig

According to your personal preference, use menuconfig or modify .config directly. Here are a few things to note:

4.1 Select Cross Compiler prefix

Here is the prefix, without gcc, to-end, as my: arm-linux-gnueabihf-; Busybox Settings-- > Build Options-- > Cross compiler prefix-Set this option equal to "arm-linux-gnueabihf-"

4.2 static compilation

Static compilation is recommended; Busybox Settings-- > Build Options-- > Build Busybox as a static binary (no shared libs)-Enable this option by pressing "Y"

4.3 does not include / usr directory

Busybox Settings-- > Installation Options-- > Don't use / usr-Enable this option by pressing "Y"

4.4 installation directory

For the install directory in the previous step, use the absolute path.

4.5 finally press [ESC] and prompt to save when saving. 5. Make & & make install$ make # compilation, if it is a multi-core CPU, such as quad-core, using make-J4 can improve the compilation speed $make install # installation 6. Send

Or use Root Explore to make / mount it readable and writable

Adb shell mkdir busyboxadb push. / bin / busybox/binadb push. / sbin / busybox/sbinexport PATH=/busybox/bin:/busybox/sbin:$PATH:7. It's over.

Take a look at the effect, and the previous adb shell is not very different. If coupled with the installation of a SSH SERVER with more fun, completely separated from adb, mainly there is VI, you can edit the keyboard remotely.
