Question About Compiling Sz81 Options

[ckblackm]

I'm trying to compile SZ81 on beta 3. First off, just doing a simple make works and it compiles, but if I try to use the
Makefile.zaurus, I get an error. The Makefile.zaurus was originally used for the standard sharp rom, but I tried to change
it so that it would match the directory structure for pdaXrom.

Here is the modified Makefile.zaurus I used:

CODE

# You won't need to alter these
TARGET=$(shell cat TARGET)
SOURCES=sdl_main.c common.c sound.c z80.c sdl_engine.c sdl_hotspots.c \
    sdl_input.c sdl_loadsave.c sdl_resources.c sdl_sound.c sdl_video.c
OBJECTS=$(patsubst %.c, %.o, $(SOURCES))
VERSION=$(shell cat VERSION)
#export PREFIX=/opt/QtPalmtop
export PREFIX=/mnt/ide2/usr/local
PACKAGE_DATA_DIR=$(PREFIX)/share/$(TARGET)

# This uses the default cross compiler directory of /opt/Embedix and
# the default QPE directory of /opt/Qtopia
#
#DEVPREFIX=/opt/Qtopia/sharp
#CC=/opt/Embedix/tools/bin/arm-linux-gcc
DEVPREFIX=/opt/native/arm/3.4.6-xscale-softvfp
CC=/opt/native/arm/3.4.6-xscale-softvfp/bin/gcc
CFLAGS=-O3 -Wall -I$(DEVPREFIX)/include \
    `$(DEVPREFIX)/bin/sdl-config --prefix=$(DEVPREFIX) --cflags` \
    -DNO_DEBUG -DQWS -DPLATFORM_ZAURUS -DVERSION=\"$(VERSION)\" \
    -DPACKAGE_DATA_DIR=\"$(PACKAGE_DATA_DIR)\" -DOSS_SOUND_SUPPORT -DSZ81
LINK=$(CC)
LDFLAGS=-L$(DEVPREFIX)/lib
LIBS=`$(DEVPREFIX)/bin/sdl-config --prefix=$(DEVPREFIX) --libs`

# You won't need to alter anything below
all: $(SOURCES) $(TARGET)

$(TARGET): $(OBJECTS)
    $(LINK) $(LDFLAGS) $(OBJECTS) $(LIBS) -o $@
    zaurus/build-$(TARGET)

%.o: %.c
    $(CC) $(CFLAGS) -c $< -o $@

.PHONY: all clean

clean:
    rm -f *.o

Here's the output I get:

CODE

Any suggestions?
If you want to play with it yourself.. you can get it from
SZ81 website

thanks,

It's gotta be something with the make file.... the regular makefile will compile without modification. Here's the regular makefile for comparison:
