sir,
that I followed this procedure.As I followed these steps:-please tell me whered did i go wrong?

    Checkout LLVM:
        cd LLVM
        svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm
    Checkout Clang:
        cd LLVM
        cd llvm/tools
        svn co http://llvm.org/svn/llvm-project/cfe/trunk clang
    Checkout Compiler-RT:
        cd LLVM
        cd llvm/projects
        svn co http://llvm.org/svn/llvm-project/compiler-rt/trunk compiler-rt
    Get the Test Suite Source Code
        cd LLVM
        cd llvm/projects
        svn co http://llvm.org/svn/llvm-project/test-suite/trunk test-suite

      5.Configure and build LLVM and Clang
        mkdir build  (inside LLVM)
        cd build
        ../llvm/configure --prefix =/home/username/LLVM/build  (path of build directory)
           make -j4
           make check-all
      6.now went to Hello folder in lib/Transform/Hello
            make (this create Hello.so in Debug+Asserts

Now I want to apply this hello pass on same Hello.cpp file(that is my file in which pass is written)
so if I compile this Hello.cpp file using command : clang -emit-llvm -c Hello.cpp(Hello.c) than it gives me following errors:-

Hello.c:15:10: fatal error: 'llvm/ADT/Statistic.h' file not found
#include "llvm/ADT/Statistic.h"

###########################now when I gave path using -I like  clang -emit-llvm -c Hello.cpp -o Hello.bc(Hello.c) -I path even then it gives errors.
