Hi,


I also tried it on Ubuntu, but got same problems, so it shouldn't be result from OS, I think

     Never seen this error. No idea.
     
                                    And if I remove the llvm-symbolizer directory and                 build again:
           
         
     
     You should never need to do that. Probably a bad idea.

     Yup. Bad idea. :)
     
                       So what is the problem there? What should I do to fix it?
         
     
     Good question. If you figure it out let us know.



I am not sure but I would guess that this is related to your CMake version. Try to get the lasted one.
 
      
     Just to get things working you might want to just concentrate on the     toolchain. For the moment it means no need for a config file either     if you do this and that makes it less effort for now.
     
     $ cd toolchain/clang
     $ make
     
     You'll see the following warning, but it's fine:
     
 ---------------------------------------------------------------------
     I: Convenience Makefile. Normally this is run from one of the target     directories
 ---------------------------------------------------------------------
     
                       And if I ran $ make CONFIG=config.mk sync-all again, following information               was displayed:                     … 
                     Unpacking                 objects: 100% (6/6), done.
              From git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux
                               7171511..68986c9  master     -> master
              make[2]: arm-linux-androideabi-gcc:                 Command not found
           
         
     
     This isn't an issue. The cross android toolchain just hasn't been     downloaded yet. It tends to happen after building clang.
     
     You can force all things to download with a:
     
     $ make CONFIG=config.mk fetch-all
     
     But this "Command not found" isn't an issue for now. It would be if     you were in the middle of compiling the kernel when it happened.
