Build target app in host machine

If you want to build your target application in host machine just by command line, you can refer to the following example:

1. Create a file, named setup-cross-environment

This file can be got by "bitbake meta-ide-support", or you can refer to the following as an example. You should modify "/sda1/poky-20100903/build-qemuppc-gcc" to your own poky build path, besides you should modify the sysroot path to fit your own cross architecture. The example is for powerpc. 

export PATH=/sda1/poky-20100903/build-qemuppc-gcc/tmp/sysroots/i686-linux/usr/bin/ppc603e-poky-linux:/sda1/poky-20100903/build-
qemuppc-gcc/tmp/sysroots/ppc603e-poky-linux/usr/bin/crossscripts:/sda1/poky-20100903/build-qemuppc-gcc/tmp/sysroots/i686-
linux/usr/sbin:/sda1/poky-20100903/build-qemuppc-gcc/tmp/sysroots/i686-linux/usr/bin:/sda1/poky-20100903/build-qemuppc-
gcc/tmp/sysroots/i686-linux/sbin:/sda1/poky-20100903/build-qemuppc-gcc/tmp/sysroots/i686-
linux//bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

export PKG_CONFIG_SYSROOT_DIR=/sda1/poky-20100903/build-qemuppc-gcc/tmp/sysroots/ppc603e-poky-linux
export PKG_CONFIG_PATH=/sda1/poky-20100903/build-qemuppc-gcc/tmp/sysroots/ppc603e-poky-linux/usr/lib/pkgconfig
export CONFIG_SITE="/sda1/poky-20100903/meta/site/endian-little /sda1/poky-20100903/meta/site/common-glibc /sda1/poky-
20100903/meta/site/ix86-common /sda1/poky-20100903/meta/site/common"
export CC=powerpc-poky-linux-gcc
export CXX=powerpc-poky-linux-g++
export CONFIGURE_FLAGS="--target=powerpc-poky-linux --host=powerpc-poky-linux --build=i686-linux"

2. Source the file

# source setup-cross-environment

3. Configure the target application

If your target application is autotool based, you should run configure like: 

# ./configure --target=powerpc-poky-linux --host=powerpc-poky-linux --build=i686-linux

4. Build the target application

# make

5. Copy the application binary into target system
