iOS problem when using Makefile for LayerKit framework

Hi experts, I'm newbie for iphone dev, no i'm learning native way to dev, when i'm using the following content in my Makefile as below


DEVICE = 192.168.1.15
APPL = MyApp

DOTH = MyApp.h
OBJS = main.o MyApp.o

SDK = /Developer/Platforms/iPhoneOS.platform/Developer
ARCH = armv6
SYSROOT= $(SDK)/SDKs/iPhoneOS2.2.sdk

CC = $(SDK)/usr/bin/arm-apple-darwin9-gcc-4.0.1 \
-arch $(ARCH) -isysroot $(SYSROOT)
CFLAGS = -std=c99 -Werror -I$(SDK)/usr/include/gcc/darwin/4.0

LD = $(CC)
LDFLAGS =\
-framework UIKit\
-framework CoreFoundation\
-framework Foundation\
-framework CoreGraphics\
-framework LayerKit\
-lobjc\
-bind_at_load

$(APPL): $(OBJS)
$(LD) $(LDFLAGS) -o $@ $^
cp $(APPL) $(APPL).app
@chmod 755 $(APPL).app/$(APPL)
@touch $(APPL).app

%.o: %.m $(DOTH)
$(CC) $(CFLAGS) -c $<


install: $(APPL)
@ssh root@$(DEVICE) /bin/rm -f /Applications/$(APPL).app/$(APPL)
scp -r $(APPL).app root@$(DEVICE):/Applications
ssh root@$(DEVICE) /usr/bin/ldid -S /Applications/$(APPL).app/$(APPL)

i'm getting error as :
ld: framework not found LayerKit
collect2: ld returned 1 exit status

but when i remove '-framework LayerKit\ ' in the LDFLAGS, its working ok, can anyone help me

thanks

thanks bro, ur correct now its using QuartzCore

i try with below code;

the below declare in .h file
-------------------------
UIPushButton *markButton;
CGColorSpaceRef colorSpace;

the below is in .m file
--------------------
markButton = [[UIPushButton alloc] initWithFrame:CGRectMake(60.0,29.0,106.0,30.0)];
[markButton setAutosizesToFit:NO];
[markButton setShowPressFeedback:YES];
[markButton setTitle😡"new game"];
[markButton setTitleColor:CGColorCreate(colorSpace,white) forState:0];


when compile, i'm getting error as below,
