Fixing a makefile to use maxmod

Post by ant512 » Sun May 08, 2011 7:33 pm

I've been fighting with this problem for a while and am getting nowhere. Can anyone tell me how to modify this makefile so that it converts all wav files in the directory "sfx" into a soundbank and includes that in the final ROM? Makefiles really aren't my thing...

Code: Select all

# WoopsiGfx Makefile 										ex:set ts=4 sw=4:
# builds the WoopsiGfx test applications, and should be sufficient for most
# needs - options are switched on/off with USE_ constants.

# set the texts that appear in the loader menus
TEXT1 		:= Earth Shaker DS
TEXT2 		:= Using WoopsiGfx
TEXT3 		:= ant.simianzombie.com

# 4-bit-deep bitmap file to use as icon in loader menus
ICON 		:= $(DEVKITPRO)/libwoopsigfx/icon/logo.bmp

#-------------------------------------------------------------------------------
# TARGET is the name of the output file
# BUILD is the directory where object files & intermediate files will be placed
# RELEASE is where the binary files will be placed
# SOURCES is a list of directories containing source code
# INCLUDES is a list of directories containing extra header files
# DEFINES is a set of -Dsym[=value] settings to pass to the compilers
#-------------------------------------------------------------------------------

TARGET		:=	$(shell basename $(CURDIR))
BUILD		:=	build
RELEASE     :=  Release
SOURCES		:=	src src/bmp data gfx
INCLUDES	:=	include include/bmp include/blocks include/levels
DEFINES		:=

# we do *not* do -o thing - WinterMute points out that this stops our
# resultant .nds from working on some loaders.  By default, ndstool puts boot
# code into the wifi-logospace and since its not visible anywhere else, its
# downright churlish for us to overwrite it.  If you want to, put it back, but
# its not the default.
# LOGO		:= -o $(CURDIR)/../data/logo_wifi.bmp
