Buildroot is a set of Makefiles and patches that makes it easy to generate a complete embedded Linux system, from the cross-compilation toolchain to the complete image for flashing.

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.

Whenever you post a question about a Buildroot build failure, please always specify the Buildroot version you're using, and attach the complete Buildroot .config file. Without these details, there is absolutely nothing that the Buildroot developers can do to help you.
