I am trying to install GraphicsMagick in Xcode4, I am getting this error when i execute command 'make'.

This problem would likely come from mixing LLVM and GCC-compiled code, such as attempting to link GCC-compiled code with the LLVM linker. Regardless, I see several postings on the net related to working-around this issue. This one suggests that building with Clang rather than LLVM-GCC will achieve a successful build:
Hi bfriesen, thanks for your suggestion, i try to follow the link you provided, but i cann't find "graphicsmagick.rb" file in my mac.
I don't know what graphicsmagick.rb is but I assume that it has something to do with the 'brew' or 'homebrew' package builder system for the Mac. I don't have an Intel Mac system here to test with (or knowledge of Xcode) so I suggest finding a forum which caters to building Intel Mac software. Google clearly shows that the problem you encountered has been encountered by others, and successfully resolved. Apparently Xcode4 provides both the Clang and LLVM-GCC compiler drivers..
Since this is first google result, I post my solution here
I works! Solved my problem, i've already given up. Thanks a lot!!!
Although there is one warning generated, but it still successfully installed. Hope this warning won't cause any problems. Anyway thanks for solving my problem again.
coders/png.c:1344:1: warning: function declared 'noreturn' should not return
1 warning generated.
The png.c warning is totally benign. It seems that the trick I used to keep GCC from warning is not working for your version of clang (it does work for other clang).
I can confirm that I also needed to use clang to get GM to build. Thanks kenshao for showing how it is done.
Platform: Mac OS X 10.7.5 (Lion) Xcode version 4.3.3
GM version: Latest head from Mercurial repo as at 24th Jan 2013
It seems that since version 4.2 of Xcode the original GCC is no longer distributed and there seems to be some incompatibility with the default llvm-gcc
This blog post gives a good overview of issues with compiler versions in recent updates to Xcode
