I'm trying to get theos working on OSX Mavericks. I recently purchased an iPhone 5s and have since then jailbroken it. Now I am trying to get Theos working so I can start working on some tweaks again. I had it working on OSX Lion and for IOS 5 and 6. I have a very simple program which should display a UIAlert when an application launches. The problem is, when i run the make command in an attempt to compile my code i get this error:
Making all for tweak test...
Preprocessing Tweak.xm...
Compiling Tweak.xm...
Linking tweak test...
Undefined symbols for architecture armv7:
"_OBJC_CLASS_$_UIAlertView", referenced from:
objc-class-ref in Tweak.xm.b0410391.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

make[1]: *** [internal-library-all_] Error 2
make: *** [test.all.tweak.variables] Error 2

Here is my code for Tweak.xm:
%hook SBApplicationIcon
-(void)launch{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"TEST" message:@"message...." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
[alert release];
%orig;
}
%end
And my makefile:
export SDKVERSION=7.0
include theos/makefiles/common.mk
TWEAK_NAME = test
test_FILES = Tweak.xm
ARCHS = armv7 arm64
test_FRAMEWORKS = UIKit
include $(THEOS_MAKE_PATH)/tweak.mk
after-install::
install.exec "killall -9 SpringBoard"
Thanks!
It's an old question, but still I figured I should answer it for people who have the same question. You need to call objc_getClass
for it to work, like this:
UIAlertView *alert = [[objc_getClass("UIAlertView") alloc] initWithTitle:@"TEST" message:@"message...." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
Note that this is not required on the left hand side of the assignment.
