Sega Genesis Dev Kit (SGDK)

Yeah, I don't use no Code::blocks nor Eclipse IDE's. I was looking for more general solution.

fun...it's because I was looking for a 'general' solution than I tried (with success) to use Eclipse...
I thought it was a very common IDE, more than PN(?)

By the term "general" I meant something more IDE independent. Eclipse is a good IDE (made some PHP development with it), a little too heavy and has too much features (probably a good thing ).
I'm looking for (MS Visual Studio) auto completion and xml code documentation, that would be some neat features, if we could agree on one widely used IDE.

I wonder if somebody could describe how is debugging possible on emulators? (Kaneda, where is part 3? )

[KanedaFr]

NM= $(GDK)bin/nm
NM2WCH= $(GDK)bin/nm2wch

rom.bin: rom.out
$(NM) -n -S -t x rom.out >rom.nm
$(NM2WCH) rom.nm rom.wch
$(OBJC) --pad-to 131072 -O binary rom.out rom.bin



then in KMod, check Options>Debug... Auto load watchers & structures
nm2wch create a watcher file from variables in your code

you're only problem will be to make >rom.nm to work
sh or cmd.exe ?

Why I can't find out some key like"fix16,u8",by press search button[/img]

I don't know why but, trying to (re)use GenDevKit, I now have a

'pearl' not recognized

and talk about not being a batch command nor an executable

any idea ? I'm under XP, same problem call direclty gcc with file and params

ps: and don't forget I updated part 3 and part 4 on my eclipse tut!

sounds like a parameter not correctly spelled. Did you tried GCC alone ? then adding parameter one by one ?

[TascoDLX]

'pearl' not recognized

Is it 'pearl' or 'perl'?

[KanedaFr]

ah ah! sorry for the mistake, it's perl, the language
it's why I don't understand.....

[Stef]

Making genesis dev in perl ? wow ! nice challenge

[KanedaFr]

ok..I figured it out....
I must say having AVR, Java, MS & Genny dev kit on the same computer IS NOT a good idea

Stef, other problem I found is make doesn't like full path (since the ':' in c:/projectpath/file.. is seen as a dependency)....
I lost my evening on this one yesterday !!!!

hop, back to coding (hard time switching from my devkit to this better one!)

Yeah GCC is very picky about what you installed on your system
About the absolute path, i'm using environnement variable as it's also more convenient. How did you fixed it ?

Glad to see you use the devkit by the way, the next version will add some news Z80 drivers and some others various stuff ^^

I use it because it's a more advanced one...

It would be could to not include the driver on a C file...and hardcoded their size...
I plan to update my MVST and I would like to easily update it.

oh, and also put the logo call out of the start().
I am not again it but I assume a lot of people desactive it (like I did myself) so call Logo_init() from our main is better than use a defined var.

Please please, don't change functions' names! I'm having a hard time learning the current ones!!

Afaik the drivers aren't included as C files, only the MVST driver is in this format because i don't have the original source :-/
Drivers are provided in .s80 file, then the makefile automatically generate C and H files

The logo is there because it's sort of "devkit" signature, as these "powered by" logo
As i know it can be annoying i added a quick way of desactivating it :p

Please please, don't change functions' names! I'm having a hard time learning the current ones!!

I'm trying to avoid that as much i can but it can happen sometime :-/
Generally new names are better

I made a makefile for the functions, and made a library out of it. That makes it much easier to handle.

Code: Select all

CC = $(GENDEV)/m68k/bin/gcc
AR = $(GENDEV)/m68k/bin/ar
RANLIB = $(GENDEV)/m68k/bin/ranlib
RM = rm -f
OBJC = $(GENDEV)/m68k/bin/objcopy
ASMZ80 = $(GENDEV)/bin/zasm
BINTOC = $(GENDEV)/bin/bin2c

#OPTION= -Dnologo_

libmd.a_OBJS = base.o tools.o vdp.o font.o vdp_bg.o vdp_dma.o \
	vdp_pal.o vdp_spr.o vdp_tile.o bitmap.o bitmapx.o z80_ctrl.o \
	tab_sin.o tab_log2.o tab_pow2.o maths.o maths3D.o ym2612.o \
	psg.o audio.o joy.o timer.o logo_lib.o z80_drv1.o z80_drv2.o \
	z80_mvst.o

INCS = -I./include
FLAGS = $(OPTION) -m68000 -Wall -O1 -c -fomit-frame-pointer $(INCS)
FLAGSZ80 = -vb2

all: z80_drv1.o80 z80_drv1.c z80_drv2.o80 z80_drv2.c md.o $(libmd.a_OBJS) libmd.a

%.a: $(libmd.a_OBJS)
	$(RM) $@
	$(AR) cru $@ $($@_OBJS)
	$(RANLIB) $@

%.o80: %.s80
	$(ASMZ80) $(FLAGSZ80) -o $@ -i $<

%.c: %.o80
	$(BINTOC) $<

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

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

clean:
	$(RM) -rf *.o *.a *.o80 *.log
	$(RM) -f z80_drv1.c z80_drv1.h z80_drv2.c z80_drv2.h

install: all
	mkdir -p $(GENDEV)/m68k/sdk
	mkdir -p $(GENDEV)/m68k/sdk/include
	mkdir -p $(GENDEV)/m68k/sdk/lib
	cp include/*.h $(GENDEV)/m68k/sdk/include
	cp libmd.a $(GENDEV)/m68k/sdk/lib
	cp md.o $(GENDEV)/m68k/sdk/lib

Then you get a simple makefile for 68K projects. Here's the one I made for the particle example:

Code: Select all

CC = $(GENDEV)/m68k/bin/gcc
RM = rm -f
OBJC = $(GENDEV)/m68k/bin/objcopy
ASMZ80 = $(GENDEV)/bin/zasm
BINTOC = $(GENDEV)/bin/bin2c

#OPTION= -Dnologo_

OBJS = main.o tranceS.o vangelisS.o

INCS = -I$(GENDEV)/m68k/include -I$(GENDEV)/m68k/sdk/include -I.
FLAGS = $(OPTION) -m68000 -Wall -O1 -c -fomit-frame-pointer $(INCS)
FLAGSZ80 = -vb2
LIBS = -L$(GENDEV)/m68k/lib -L$(GENDEV)/m68k/sdk/lib -lmd -lgcc

all: rom.bin

rom.bin: rom.out
	$(OBJC) --pad-to 3145728 -O binary rom.out rom.bin

rom.out: $(OBJS)
	$(CC) -T $(GENDEV)/m68k/lib/md.ld -nostdlib $(GENDEV)/m68k/sdk/lib/md.o $(OBJS) $(LIBS) -o rom.out

%.o80: %.s80
	$(ASMZ80) $(FLAGSZ80) -o$@ $<

%.c: %.o80
	$(BINTOC) $<

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

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

clean:
	$(RM) -rf *.o *.a *.o80 *.out *.bin

COOOOL!! I was about to make it

I just need to confirm something...I know it could be some kind of newbie question, but I never worked with my own lib :
with a lib, will the linker include ONLY used functions or the full lib ?

only the MVST driver is in this format because i don't have the original source

Like everything I made, the source is available Look http://gendev.spritesmind.net/page-mvst.html

The logo is there because it's sort of "devkit" signature

I would be ok if it was a "Powered by GenesisDevKit" but flemteam means nothing...
When I mean "nothing", I mean people won't find genesis dev searching flemteam on google.
I have no problem using the powered by MVST logo when I used Pascal version since I knew MVST search will result in Pascal's or Ivan's website.

Else we have to make a flemteam website.
I could make a subdomain with last version and demos of everyone but it won't be fair : flemteam isn't spritesmind.

Sorry it's my "genesis dev for everyone" syndrom

ps: for the people who could think that : no, I don't mean I want the Spritesmind logo !
