Either i'm an idiot (Highly likely) or I missed it in the docs somewhere that when writing code that uses the SDL framework one must pass the -noixemul flag to gcc otherwise running the compiled binary locks up MorphOS completely.

Justy thought I'd mention it here to save anyone else a similar headache.

Two more points:

1. to compile a SDL source, the usage it to put `sdl-config --cflags` on the gcc commande line. This will add the -noixemul switch and the right include path. And use `sdl-config --libs` to link.

2. -noixemul should pretty much be used for... everything. As soon as you make something doing any non-ixemul library call, use -noixemul. Always. An OpenGL call? An exec.library call? A z.library call? Anything not being part of ixemul's libc API? Use -noixemul.

Thanks for the tips Henes.

I generally use -noixemul but I left it off the command line by accident and spent the next half an hour convinced I was going mad. :)

Will make sure to use sdl-config in future.

A noob question. How do I include the SDLconfig file in the command line to compile properly?

The same way as on other systems:
gcc -O3 `sdl-config --cflags` -c foo.c -o foo.o
gcc `sdl-config --libs` foo.o -o foo

Please notice the backtick usage.

Thanks Henes. I've never used the config file. Time to do thing right. ;)

Thanks Intuition! It will be useful when I repair my two macs.
I was doing some SDL stuff.

Code:

CXX = ppc-morphos-g++
STRIP = ppc-morphos-strip

CFLAGS = -O3 -Wall `sdl-config --cflags`
LDFLAGS = `sdl-config --libs`

SOURCES = image.cpp
OBJECTS = $(SOURCES:.cpp=.o)
EXECUTABLE	= image

all: $(SOURCES) $(EXECUTABLE)
	
$(EXECUTABLE): $(OBJECTS)
	@echo "Linking object code and creating executable...."
	@$(CXX) $(CFLAGS) $(OBJECTS) -o $@ $(LDFLAGS)
	
	@echo "Stripping extraneous data from executable...."
	@$(STRIP) --strip-all $(EXECUTABLE)
	
	@echo LZMA-packing executable....
	@copy C:lzmaLoader $(EXECUTABLE).packed
	@lzma e $(EXECUTABLE) -so >>$(EXECUTABLE).packed
	@echo
	@echo "All done!"
	@echo
	@echo "Executable filename is: '$(EXECUTABLE)'"
	@echo "Packed executable filename is: '$(EXECUTABLE).packed'"
	@echo

.cpp.o:
	@echo "Compiling object code...."
	@$(CXX) $(CFLAGS) -c $< -o $@
	
clean:
	@rm -f $(OBJECTS) $(EXECUTABLE) $(EXECUTABLE).packed
	@echo "All objects and executables have been cleaned."
	@echo

You can delete the LZMA-loader lines if you want, or just copy lzma, lzmaLoader and lzmaLoader_shared to C:
