Buildroot is a set of Makefiles and patches that makes it easy to generate a complete embedded Linux system. Buildroot can generate any or all of a cross-compilation toolchain, a root filesystem, a kernel image and a bootloader image. Buildroot is useful mainly for people working with small or embedded systems, using various CPU architectures (x86, ARM, MIPS, PowerPC, etc.) : it automates the building process of your embedded system and eases the cross-compilation process.

See also cross-compiling.

To enable a serial support in tcl [1 ] a workaround is necessary... by setting the environment variable tcl_cv_api_serial to "termios".

A special fork of the main buildroot is available with the latest Tcl/Tk (8.6) and an update Tcllib, as well as several other extensions. That fork is maintained by sdw available on github at [2 ]
