Using Poky generated host SDK
|
||
|
=============================
|
||
|
|
||
|
How to build host SDK
|
||
|
====
|
||
|
|
||
|
You need to setup Poky and then run one command:
|
||
|
|
||
|
$ bitbake meta-toolchain
|
||
|
|
||
|
Result would be tarball in tmp/deploy/sdk/ with everything needed to build for
|
||
|
your target device. Unpack this in / directory - toolchain will reside in
|
||
|
/usr/local/poky/arm/ dir.
|
||
|
|
||
|
Usage of SDK
|
||
|
=====
|
||
|
|
||
|
First add toolchain into PATH:
|
||
|
|
||
|
$ export PATH=/usr/local/poky/arm/bin/:$PATH
|
||
|
|
||
|
Compiler is 'arm-poky-linux-gnueabi-gcc'. Building 'helloworld' example is
|
||
|
simple:
|
||
|
|
||
|
$ arm-poky-linux-gnueabi-gcc hello.c -o hello
|
||
|
$ file hello
|
||
|
hello: ELF 32-bit LSB executable, ARM, version 1 (SYSV), for GNU/Linux 2.6.14, dynamically linked (uses shared libs), not stripped
|
||
|
|
||
|
Autotools and SDK
|
||
|
======
|
||
|
|
||
|
'Configure' scripts allow to specify Host, Target, Build architecture. To build
|
||
|
with Poky SDK you need to specify:
|
||
|
|
||
|
./configure --target=arm-poky-linux-gnueabi --host=arm-poky-linux-gnueabi
|
||
|
|
||
|
|
||
|
Using packages from Poky
|
||
|
========
|
||
|
|
||
|
During development it is often situation that we want to use some libraries
|
||
|
which are available in Poky build. Their packages need to be unpacked to
|
||
|
/usr/local/poky/arm/arm-poky-linux-gnueabi/ directory.
|
||
|
|
||
|
For example to add libiw (from wireless-tools package) you need to unpack two
|
||
|
packages:
|
||
|
|
||
|
libiw29_29-pre20-r0_armv5te.ipk
|
||
|
libiw-dev_29-pre20-r0_armv5te.ipk
