Hello community

My environment is i.MX6Q and android 4.4.2.

I modified some commands in busybox then I want to compile it,I follow busybox on the i.MX6 sabre sd platform in a few commands ,and these are my steps:

$ cd myandroid/external/busybox

$ export ARCH=arm

$ export CROSS_COMPILE=~/myandroid/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi-

$ make defconfig

$ sed -i.orig 's/^#.*CONFIG_STATIC.*/CONFIG_STATIC=y/' .config

$ make

When I make,I got fail,like below:

CC      applets/applets.o

applets/applets.c:10:20: fatal error: assert.h: No such file or directory

compilation terminated.

make[1]: *** [applets/applets.o] Error 1

make: *** [applets_dir] Error 2

So,please tell me how to compile busybox?

Thank You

Qiulong Li

It's tool-chain issue. Please use ltib (or Yocto) toolchain instead of Android's.

Hello all,

I've downloaded, installed and built YOCTO to compile busybox 1.24.2

I have ran the following steps:

1.- MACHINE=imx6dlsabresd DISTRO=poky source ./setup-environment base

2.- bitbake meta-toolchain

3.- executed fslc-wayland-glibc-x86_64-meta-toolchain-armv7at2hf-neon-toolchain-2.2.2.sh to install the SDK

4.- executed environment-setup-armv7at2hf-neon-fslc-linux-gnueabi from the console in which I am running the make of the busybox.

Hi,Jay

          You are right,use $ make CROSS_COMPILE=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/arm-fsl-linux-gnueabi- ,then it works!

Thank You

Hi,Qiulong

                 I have the same problem now.I use $make menuconfig to selecte the Cross Compiler prefix ,but also report error.

I think the reason is the path for Makefile .but i dont know how to do.

It may be due to incompatibility between the busybox version and the toolchain version used for compiling busybox.

You can try a different version of toolchain and check.

Hello Qiulong,

     Actually, the question is not in our support range, but I can give you some advice.

(1) Downloading new version if busybox from it's source code website.

(2)Adjusting it's Makefile according to the path of cross-compiler in your linux system.

(3)Compiling it by static mode(this mode will compile libs into those commands you want)

(4)After compiling, copy those .bin files in output directory to /system/bin/ of android.

(or, make a subdirectory, such as 'bin' in root directroy)

(5) Adding your commmand path to init.rc ( for example add /bin/ in path prameter)

   Hope above items can help you !

Regards,

Weidong

Hello Weidong

     It’s very kind of you to give me this advice.

     My busybox source code ( located at ~/myandroid/external/busybox ) and the binary file busybox ( located at ~/myandroid/device/fsl-proprietary/test/bin/busybox ) came from android_kk4.4.2_1.0.0-ga_core_source.tar.gz which download from freescale .So , when I patch code for i.MX, I got busybox source code and binary file,but I don't kown how to make the binary file from the source code.

     I'm stuck here for a long time,please help me out.

Thank You

Qiulong Li
