If you wish to persist any # information pertaining to the build process, it is recomended that you # utilize the BSP settings mechanism to do so. # # Note that most variable assignments in this section have a corresponding BSP # setting that can be changed by using the nios2-bsp-create-settings or # nios2-bsp-update-settings command before nios2-bsp-generate-files; if you # want any variable set to a specific value when this Makefile is re-generated # (to prevent hand-edits from being over-written), use the BSP settings # facilities above. #------------------------------------------------------------------------------ #START MANAGED # The following TYPE comment allows tools to identify the 'type' of target this # makefile is associated with. # TYPE: BSP_PRIVATE_MAKEFILE # This following VERSION comment indicates the version of the tool used to # generate this makefile. A makefile variable is provided for VERSION as well. # ACDS_VERSION: 22.1 ACDS_VERSION := 22.1 # This following BUILD_NUMBER comment indicates the build number of the tool # used to generate this makefile. # BUILD_NUMBER: 917 SETTINGS_FILE := settings.bsp SOPC_FILE := ../../niosII.sopcinfo #------------------------------------------------------------------------------- # TOOL & COMMAND DEFINITIONS # # The base command for each build operation are expressed here.

This content of this variable is # directly passed to the archiver rather than the more standard "ARFLAGS". The # reason for this is that GNU Make assumes some default content in ARFLAGS. # This setting defines the value of BSP_ARFLAGS in Makefile. BSP_ARFLAGS = -src # Custom flags only passed to the assembler. This setting defines the value of # BSP_ASFLAGS in Makefile. BSP_ASFLAGS = -Wa,-gdwarf2 # C/C++ compiler debug level. '-g' provides the default set of debug symbols # typically required to debug a typical application. Omitting '-g' removes # debug symbols from the ELF. This setting defines the value of # BSP_CFLAGS_DEBUG in Makefile. BSP_CFLAGS_DEBUG = -g # C/C++ compiler optimization level. "-O0" = no optimization,"-O2" = "normal" # optimization, etc. "-O0" is recommended for code that you want to debug since # compiler optimization can remove variables and produce non-sequential # execution of code while debugging. This setting defines the value of # BSP_CFLAGS_OPTIMIZATION in Makefile. BSP_CFLAGS_OPTIMIZATION = -O0 # C/C++ compiler warning level. "-Wall" is commonly used.This setting defines # the value of BSP_CFLAGS_WARNINGS in Makefile. BSP_CFLAGS_WARNINGS = -Wall # C compiler command. CC = nios2-elf-gcc$(WINDOWS_EXE) -xc # C++ compiler command. CXX = nios2-elf-gcc$(WINDOWS_EXE) -xc++ # Command used to remove files during 'clean' target. RM = rm -f #------------------------------------------------------------------------------- # BUILD PRE & POST PROCESS COMMANDS # # The following variables are treated as shell commands in the rule # definitions for each file-type associated with the BSP build, as well as # commands run at the beginning and end of the entire BSP build operation. # Pre-process commands are executed before the relevant command (for example, # a command defined in the "CC_PRE_PROCESS" variable executes before the C # compiler for building .c files), while post-process commands are executed # immediately afterwards. # # You can view each pre/post-process command in the "Build Rules: All & # Clean", "Pattern Rules to Build Objects", and "Library Rules" sections of # this Makefile. #------------------------------------------------------------------------------- #------------------------------------------------------------------------------- # BSP SOURCE BUILD SETTINGS (FLAG GENERATION) # # Software build settings such as compiler optimization, debug level, warning # flags, etc., may be defined in the following variables. The variables below # are concatenated together in the 'Flags' section of this Makefile to form # final variables of flags passed to the build tools. # # These settings are considered private to the BSP and apply to all library & # driver files in it; they do NOT automatically propagate to, for example, the # build settings for an application. # # For additional detail and syntax requirements, please refer to GCC help # (example: "nios2-elf-gcc --help --verbose"). # # Unless indicated otherwise, multiple entries in each variable should be # space-separated. #------------------------------------------------------------------------------- # Altera HAL alt_sys_init.c generated source file GENERATED_C_FILES := $(ABS_BSP_ROOT)/alt_sys_init.c GENERATED_C_LIB_SRCS += alt_sys_init.c #------------------------------------------------------------------------------- # BSP SOURCE FILE LISTING # # All source files that comprise the BSP are listed here, along with path # information to each file expressed relative to the BSP root.
