iOS building static libraries independently giving error

[app2011]

I need to add the external static libraries for integrating the linkedIn with my application. When i set build target to one of project (from edit schema and then selecting the build target )then, build tends to fail. My linkedInclientlibrary have issues:

`cc1obj: error: unrecognized command line option "-fno-objc-arc"

(CompileC /Users/k.shinde/Library/Developer/Xcode/DerivedData/the-life-doctor-gmxqpvlwylxoiletpigdjxwgpodv/Build/Intermediates/LinkedInClientLibrary.build/Debug-iphonesimulator/LinkedInClientLibrary.build/Objects-normal/i386/RDLinkedInAuthorizationController.o RDLinkedInAuthorizationController.m normal i386 objective-c com.apple.compilers.gcc.4_2
cd "/Users/k.shinde/Desktop/myexp/LinkedInClientLibrary )"

and OAuthlibrary gives issue:

coCommand /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/libtool failed with exit code 1.
(Libtool /Users/k.shinde/Library/Developer/Xcode/DerivedData/the-life-doctor-gmxqpvlwylxoiletpigdjxwgpodv/Build/Products/Debug-iphonesimulator/libOAuthConsumer_iPhone.a normal i386)

Plz help me solve out these errors.

Try changing the compiler from gcc to clang.

adding multiple header path in project

Try changing the compiler from gcc to clang.

i resolved that errors. i guess the compiler was not getting the header files. I build the project targets independently that are added in my project and observed dependencies, link binary with files in 'build phases'-tab. Now i am getting problem in my controllers , when i add header in my controller it says header not find, but every thing is fine when i build the projects targets of fb, linkedIn separately. how to add multiple header search path in our project.
