I'm trying to create an app with Theos on my iPhone 6, but when I type "make package install" in MobileTerminal, it always says the same error:

`theos/makefiles/common.mk:115: *** The "iphone" target is not supported on the "" platform. Stop.`

I used "Theos Tutorials" by ReverseEffect, and it shows that error every time no matter what I do. I have iOS 8.1 sdks downloaded and I'm running iOS 8.4 on the TaiG jailbreak.

Here is my makefile:

```
include theos/makefiles/common.mk

APPLICATION_NAME = Hello
Hello_FILES = main.m HelloApplication.mm RootViewController.mm
Hello_FRAMEWORKS = UIKit Foundation

include $(THEOS_MAKE_PATH)/application.mk

```
