llvm 2.9 can not generate doxygen files

I  have solved the problem for the whole night XD.

In fact, it is dissuced in llvm mailing list. What you have to do is to patch the file, reconfigure, recompile and finish the problem. (When I find ethe soluion, I feel I am a stupid guy. Why do I find llvm mailing list first ?)

You can download the path for generating doxygen files from Here.

The following is my personal note for the problem.

---

1. First, you have to install graphviz
   
   
   1. For MacOSX
      
      

       brew install graphviz
      

      
      If you meet some problem with Mac OSX 10.7 Lion, There are some linking library errors (The issuse is dissued in github: homebrew issues 6645). Just type
      
      

       cd /usr/X11/lib
       sudo ln -s libpng12.0.dylib libpng12.dylib
      
      

   2. For Fedora/ CentOS
      
      

       sudo yum install graphviz -y
      
      

2. Patch to support llvm 2.9 can generate the doxygen files
   (The issue is dissued in mailing list)
   
   

    cp doxygen.patch $HOME/usr/src/llvm-2.9
    cd $HOME/usr/src/llvm-2.9
    patch -p1 < doxygen.patch
   
   

3. Add the option in configure command and reconfigure, recompile
   
   

    ./configure --prefix=$HOME/usr --with-clang=$HOME/usr --enable-debug-symbols=yes --enable-debug-runtime=yes --enable-shared --enable-static --with-pic --enable-pic --with-clang=$HOME/usr  --enable-doxygen
    make -j4   # It's upto your computer
    make install
