+ * Resolution |
+ *
+ *
+ * | Error "relocation truncated to fit: R_AVR_13_PCREL against symbol {X}" shown when compiling. |
+ * Try compiling with the setting LINKER_RELAXATIONS=N in your LUFA Build System 2.0 makefile, or remove the line -Wl,--relax
+ * from other makefiles. 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 aformentioned boolean values, and other values are invalid. Set this option to either Y or N and try again. |
+ *
+ *
+ * | 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. |
+ *
+ *
+ * | Error "Doxygen configuration file {X} does not exist" shown when upgrading a Doxygen configuration file. |
+ * The nominated Doxygen configuration file, specified in the user project's DOXYGEN_CONF parameter, could not be found. 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 "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 "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 micocontroller 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 "error: invalid suffix "x" on integer constant" shown when compiling a bootloader. |
+ * This is usually caused by the bc.exe application not being found in the system's PATH variable. Make sure you have the bc.exe tool
+ * installed correctly (see \ref Sec_Prerequisites). |
+ *
+ *
+ * | 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_SOURCES). |
+ *
