    how can i change the xcode from 32 bit to 64 bit. I am getting a error in running a program :

    (5209) malloc: *** mmap(size=2097152) failed (error code=12)
    *** error: can't allocate region
    *** set a breakpoint in malloc_error_break to debug

    How can i solve this error..

    First, you shouldn't double post.
    Second, your error looks like a memory allocation error in your program, not in XCode.
    Third, if you actually want to run XCode in 64-bit (this is not a good idea!), go to /Developer/Applications, Get Info on XCode and uncheck open in 32 bit mode.
