use of undeclared identifier 'OFILE_LLVM_BITCODE'

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install clang 3.2-1 from Ubuntu 13.04 or clang 3.4-1 on Debian from LLVM APT.
2. ./configure --target=arm-apple-darwin11 --prefix=/usr && make
3. Get error 

What is the expected output? What do you see instead?
libtool.c:1369:38: error: use of undeclared identifier 'OFILE_LLVM_BITCODE'
                            ofiles[i].arch_type == OFILE_LLVM_BITCODE){
                                                   ^
1 error generated.

What version of the product are you using? On what operating system?
Ubuntu 13.04/Debian 7.0

Please provide any additional information below.

I found definition of OFILE_LLVM_BITCODE in file /include/stuff/ofile.h

enum ofile_type {
    OFILE_UNKNOWN,
    OFILE_FAT,
    OFILE_ARCHIVE,
    OFILE_Mach_O
#ifdef LTO_SUPPORT
    ,
    OFILE_LLVM_BITCODE
#endif /* LTO_SUPPORT */
};

When I remove the LTO_SUPPORT condition and make again I get

lto_file.cpp:47:10: fatal error: 'llvm-c/lto.h' file not found
#include "llvm-c/lto.h"
         ^
1 error generated.

after adding #define LTO_SUPPORT to the beggining of ofile.h I get :

`ofile_specific_member':

 clang: error: linker command failed with exit code 1 (use -v to see invocation)

Any ideas ? I've tryed building under both - Ubuntu and Debian both 64bit in 
newest versions with all updates installed (Clang versions mentioned above).

Even tried on Fedora 19 with Clang 3.4 both 64 bit, still the some.

Same problem in same platform Ubuntu 13.04.

You all need the LLVM development packages installed.

    ubuntu$ sudo apt-get install llvm-dev

    fedora$ sudo yum install llvm-devel

It should probably be mentioned on the how-to page, though.

Yes, just as scottywz said, you need install llvm development package which 
containes lto.h.

LTO is a common feature that llvm provides, It should always be there.

It seems I should change configure script to detect the header and give a hint.

the cctools 1.3 and iphonesdk-utils 2.0 in download sections had been tested 
with ubuntu 13.04 with clang/llvm-3.2. 

Since the clang/llvm-3.2 package shipped with ubuntu use a customized path to 
hold headers and libraries, please refer to "Howto" in wiki sections to setup 
proper Header path for ubuntu.
