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:
# 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))

Here's the output I get:

Any suggestions?
If you want to play with it yourself.. you can get it from
SZ81 website (http://sz81.sourceforge.net/)
thanks,

It looks to me like you don't have a main function. All C programs must have one function called main(). I vaguely recall that SDL does something weird with main, perhaps using #defines ? I don't know but I would check your SDL set up and then take a look at sdl_main.c

It's gotta be something with the make file.... the regular makefile will compile without modification. Here's the regular makefile for comparison:
# Comment/uncomment these to choose an installation destination
# System wide installation

Edit: Scratch what I said.
Wait, why are you trying to compile with the Zaurus makefile if you can compile with the standard makefile ?
-
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.
