Twitter OAuth iPhone problem

I'm adding a twitter module on my program for both iPhone and iPad. And I have met two problems.

1st, on iPhone. After I merged my twitter module to my iPhone program, build fails only in Debug mode. It's ok in Release mode.

The error message is simply 

Libxml/xmlreader.h: No such file or directory

Yes, it is because gcc can't locate it. But I have added -lxml2 for Other Linker Flags, and /usr/include/libxml2/** for Header Search Paths in project build settings on Release and Debug mode both.

2nd, on iPad. After I merged twitter module to iPad program, build fails with the message below.

ld: duplicate symbol _OBJC_METACLASS_$_MGTwitterEngine in 
/Users/eddy/Documents/iOS/workspace/.../i386/MGTwitterEngine-3460BD6C4381A3AC.o and  
/Users/eddy/Documents/iOS/workspace/.../i386/MGTwitterEngine-CC42501E82512F61.o

Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2 
failed with exit code 1

I can't figure out the reason why this message comes. Is the readymade module only for iPhone? Or how can I fix it?

  1. Add "/usr/include/libxml2" in the header search path field of your project settings.

  2. You have added the 2 files of same name(here MGTwitterEngine) to the same target.
