[Z88dk-users] R: Z88dk-users digest, Vol 1 #64 - 3 msgs

Hi,

Looking around some forums says that sdcc is quite large to fit in a zx
spectrum so i used z88dk.

This is a primary test, if it's work a bit I'll work seriously to the
porting.

The bad thing is that I do know how to use a generic "make" command to
manage the sources.

Thak you for the interest.

vittorio

Subject: [Z88dk-users] Symbol <_P> redefined in module 'CTK' error

Hi,

this is my problem.

i have 2 sources:

ctk.c
program-handler.c

and i try to compile with this cmdline:

zcc +zx -O3 -no-cleanup -lndos -oprogram.bin main.c ek.c arg.c
program-handler.c ctk.c ctk-draw.c timer.c ek-service.c

but this is the output:

The problem seems to be in EV_EVENTHANDLER

Any suggestions???

Hi,

this is my problem.

i have 2 sources:

ctk.c
program-handler.c

and i try to compile with this cmdline:

zcc +zx -O3 -no-cleanup -lndos -oprogram.bin main.c ek.c arg.c
program-handler.c ctk.c ctk-draw.c timer.c ek-service.c

[snip]

you are trying to compile/port contiki right? i'd give sdcc a try then,
z88dk
isnt quite capable of compiling contiki (even sdcc, which is quite a bit
more
standard compliant, needs a few hacks)

This is my source code:


Program-handler.c

#include <string.h>

Some include stuff....


extern unsigned char ctk_menuitem_add(struct ctk_menu *menu, char *name);
extern void ctk_icon_add(struct ctk_widget *icon, ek_id_t id);
extern void ctk_menu_new(struct ctk_menu *menu, char *title);
extern void ctk_menu_add(struct ctk_menu *menu);
extern ek_id_t ek_start(struct ek_proc *p);


...code...


EK_EVENTHANDLER(program_handler_eventhandler, ev, data);
EK_PROCESS(p, "Program handler", EK_PRIO_NORMAL,
program_handler_eventhandler, NULL, NULL);

/*-------------------------------------------------------------------------

-

---------*/


Ctk.c


...include stuff...

EK_POLLHANDLER(ctk_poll);
EK_EVENTHANDLER(ctk_eventhandler, ev, data);
EK_PROCESS(p, "CTK Contiki GUI", EK_PRIO_NORMAL, ctk_eventhandler,
ctk_poll, NULL);


The problem seems to be in EV_EVENTHANDLER

Actually I think it's in EK_PROCESS.  Is that a macro that creates
a data structure named "p"?  It looks like it is...

If there is supposed to be one such data structure per file (with
one process per c file) -- again I am not familiar with contiki --
is there maybe missing a static declaration so that the "p"
data structure isn't made global?

Have a look at your two asm files again; if either one of them
have an "XDEF _p" in them then the local "_p" data structures
are being made global and you have two different p data structures
being referenced with the same name...

From what I remember long ago, contiki needed function pointer

typedefing and mulit-dimensional array support which z88dk is
missing.  it's possible to work around, of course, but that would
involve changing the source quite a bit.  Maybe that's what
you're doing? :-)
