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,
Christopher.

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

CODE
# Comment/uncomment these to choose an installation destination
# System wide installation
#PREFIX?=/usr/local
#BINDIR?=$(PREFIX)/bin
#DOCDIR?=$(PREFIX)/share/doc/$(TARGET)
#PACKAGE_DATA_DIR?=$(PREFIX)/share/$(TARGET)

# Local installation within your home folder
#PREFIX?=$(HOME)/Games/$(TARGET)
#BINDIR?=$(PREFIX)
#DOCDIR?=$(PREFIX)/doc
#PACKAGE_DATA_DIR?=$(PREFIX)/data

# Run from current folder i.e. no installation
PREFIX?=.
BINDIR?=$(PREFIX)
DOCDIR?=$(PREFIX)
PACKAGE_DATA_DIR?=$(PREFIX)/data

# For sz81 OSS_SOUND_SUPPORT is now synonymous with SDL_SOUND_SUPPORT.
# Comment this out if you don't want sound support.
SOUNDDEF=-DOSS_SOUND_SUPPORT

# 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)

# These should be ok for most.
# For debugging/profiling uncomment the following two lines:
#CFLAGS=-O0 -g -pg
#LDFLAGS=-pg
SDL_CONFIG?=sdl-config
CFLAGS?=-O3
CFLAGS+=-Wall `$(SDL_CONFIG) --cflags` -DVERSION=\"$(VERSION)\" \
    -DPACKAGE_DATA_DIR=\"$(PACKAGE_DATA_DIR)\" $(SOUNDDEF) -DSZ81
LINK=$(CC)
LDFLAGS=
LIBS=`$(SDL_CONFIG) --libs`

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

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

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

.PHONY: all clean install

open%:
    -@if [ -n "`which pasmo 2> /dev/null`" ]; then \
        pasmo -v open8x/$@.asm open8x/$@.rom; \
        if [ -f open8x/$@.rom -a ! -e data/zx$*.rom ]; then \
            cp open8x/$@.rom data/zx$*.rom; \
        fi \
    else \
        echo "The Pasmo cross-assembler was not found: skipping $@"; \
    fi

clean:
    rm -f *.o

install:
    @if [ "$(PREFIX)" = . ]; then \
        echo "Installing into the current folder is not allowed."; \
        exit 2; \
    fi
    mkdir -p $(BINDIR)
    mkdir -p $(DOCDIR)
    mkdir -p $(PACKAGE_DATA_DIR)
    cp $(TARGET) $(BINDIR)
    cp AUTHORS COPYING ChangeLog NEWS README $(DOCDIR)
    cp data/*.bmp $(PACKAGE_DATA_DIR)
    @if [ -f data/zx80.rom ]; then cp data/zx80.rom $(PACKAGE_DATA_DIR); fi
    @if [ -f data/zx81.rom ]; then cp data/zx81.rom $(PACKAGE_DATA_DIR); fi
    
uninstall:
    @echo "Uninstalling is not currently implemented."
