Alternatively, make sure you have the latest version of the Atmel Toolchain installed for your system.
Error "error: ld terminated with signal 11 [Segmentation fault]" shown when compiling.Try compiling with the setting DEBUG_LEVEL=2 in your LUFA Build System 2.0 makefile, or make sure you are using binutils version 2.22 or later.
Error "EMERGENCY ABORT: INFINITE RECURSION DETECTED" shown when compiling.Make sure you are using an up to date version of GNU Make when compiling. This error is a safety system added to the mid-level makefiles, to prevent an issue with + * GNU make or other variants of Make causing an infinitely recursive build.
Error "Unsupported architecture "{X}"" shown when compiling.Ensure your makefile's ARCH setting is set to one of the architecture names (case-sensitive) supported by the version of LUFA you are compiling against.
Error "Makefile {X} value not set" shown when compiling.The specified Makefile value was not configured in your project's makefile or on the command line, and the nominated setting is required by one or more LUFA + * build system modules. Define the value in your project makefile and try again.
Error "Makefile {X} option cannot be blank" shown when compiling.The specified Makefile value was configured in your project's makefile or on the command line, but was set to an empty value. For the nominated configuration + * option, an empty value is not allowed. Define the nominated setting to a correct non-blank value and try again.
Error "Makefile {X} option must be Y or N" shown when compiling.The specified Makefile value was configured in your project's makefile or on the command line, but was set to a value other than a Y (for "Yes") or "N" (for "No"). + * This configuration option is required to be one of the aforementioned boolean values, and other values are invalid.

Error "Unknown input source file formats: {X}" shown when compiling.The nominated source files, specified in your project's makefile in the SRC configuration option, has an extension that the LUFA build system does not + * recognise. The file extensions are case sensitive, and must be one of the supported formats (*.c, *.cpp or *.S).
Error "Cannot build with OBJDIR parameter set - one or more object file name is not unique" shown when compiling.When a project is built with a non-empty OBJDIR object directory name set, all input source files must have unique names, excluding extension and path. + * This means that input files that are named identically and differ only by their path or extension are invalid when this mode is used.
Error "Source file does not exist: {X}" shown when compiling.The nominated input source file, specified in the user project's SRC parameter, could not be found. Ensure the source file exists and the absolute or + * relative path given in the user project makefile is correct and try again.

Ensure the configuration file exists + * and the absolute or relative path given in the user project makefile is correct and try again, or run the appropriate makefile target to generate a new configuration + * file.
Error "avr-gcc: error: unrecognized option '{X}'" shown when compiling.An unrecognised option was supplied to the compiler, usually in the C_FLAGS, CPP_FLAGS, ASM_FLAGS or CC_FLAGS configuration + * options. The nominated compiler switch may be invalid, or unsupported by the version of AVR-GCC on the host system. Remove the unrecognised flag if invalid, or + * upgrade to the latest AVR-GCC. If the option is a valid linker option, use the prefix "-Wl," to ensure it is passed to the linker correctly.
Error "makefile:{X}: {Y}.mk: No such file or directory" shown when make is invoked.The path to the nominated makefile module was incorrect. This usually indicates that the makefile LUFA_PATH option is not set to a valid relative or + * absolute path to the LUFA library core.
Error "fatal error: LUFAConfig.h: No such file or directory" shown when compiling.The USE_LUFA_CONFIG_HEADER compile time option was set in the user project makefile, but the user supplied LUFAConfig.h header could not be + * found. Ensure that the directory that contains this configuration file is correctly passed to the compiler via the -I switch in the makefile CC_FLAGS + * parameter.
Error "ld.exe: section .apitable_trampolines loaded at {X} overlaps section .text" shown when compiling a bootloader.The bootloader is compiling too large for the given FLASH_SIZE_KB and BOOT_SECTION_SIZE_KB parameters set in the bootloader makefile. This + * usually indicates that these values are incorrect for the specified device the bootloader is targeting. If these values are correct, a newer version of the + * compiler may need to be used to ensure that the bootloader is built within the section size constraints of the target device.
Error "unknown MCU '{X}' specified" shown when compiling.The specified microcontroller device model name set in the user application's makefile as the MCU parameter is incorrect, or unsupported by the + * version of the compiler being used. Make sure the model name is correct, or upgrade to the latest Atmel Toolchain to obtain newer device support.
Error "undefined reference to `{X}'" shown when compiling.This is usually caused by a missing source file in the user application's SRC configuration parameter. If the indicated symbol is one from the LUFA + * library, you may be missing a LUFA source makefile module (see \ref Page_BuildModule_LUFA_SOURCES).
