Compiling on the device. RPM of Group Development/Tools. that automates the process of building a cross­compiling toolchain and a root filesystem for an embedded system. I am attempting to build Valgrind for the MIPS64-based Cavium. 1°) Obtaining a cross-toolchain for ARM architecture. These are instructions to take a Linaro build for 96Boards and cross compile applications to run in that build. In case you want to take a shortcut here are the modified makefiles. 1 to OpenWRT Barrier libnuma is not available in OpenWrt you have to create a package in buildroot or compile it with the SDK. It is comparable to Yocto in spirit, but much simpler. The concept sounds pretty cool. Building a cross compiling toolchain is a good exercise, but if you need to have a suite of tools/libs, check out llnl's spack. uClibc is an alternate C library, which features a much smaller footprint. x uses the waf build system which isn't very cross-compile friendly, and also some tests are formulated in a way that isn't cross-build friendly either by needing to run them. Then you need to download the OpenWRT source code and configure it for the Yun (I think it defaults to the right settings).

For this and as the original author stated, buildroot will be used. Buildroot has been initially developed by uClibc developers. Tools such as Scratchbox can provide a simulated SH-Mobile environment, or alternatively tools such as Buildroot or OpenEmbedded provide a better environment for cross-compilation. Buildroot is a fine build system, which makes deploying Linux on embedded platforms really easy. Cross compiler tools are used to generate executables for embedded system or multiple platforms. Having a working cross toolchain is the starting point of a journey, not the end of it. Buildroot is useful mainly for people working with small or embedded systems. In the embedded Linux unfortunately the things are a bit different. Most likely, you need to go in make menuconfig , and change the option in which you declare the version of the kernel headers (under the Toolchain menu). Without rely on the C.
