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 Copyright (C) 2006-2007 OpenedHand Ltd.
