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
# make -f Makefile.zaurus

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

thanks,

I would have thought that you should be able to use the regular makefile if you are compiling on pdaXrom just make sure that make can find gcc etc.

If you want to use the Zaurus makefile then you probably want to remove the -DPLATFORM_ZAURUS from CFLAGS as well as the changes you made. It would be worth grepping the code to find what is changed when PLATFORM_ZAURUS is defined.
