I'm try to build to build Clang and LLVM and after download it I want to configure it so when I do that command :

../llvm/configure --prefix=/usr/clang_3_3 --enable-optimized --enable-targets=host

it's show me error configure permission Denied even when I'm root and I try

chmod +x

Note : I download Clang and LLVM from svn and I put it to anthor dir(not the root) in /media one of these dirs

Are these files on an external hard disk? Try putting them in your ~ home directory instead. – minerz029 Sep 18 '13 at 23:04

You need to put it on a Linux file system. Microsoft Windows file-systems do not support setting the executable bit.

Try these workarounds:

  • You could run it like (with bash in front, assuming it opens with bash)

    bash ../llvm/configure --prefix=/usr/clang_3_3 --enable-optimized --enable-targets=host
  • You could create a small ext4 partition on an external hard drive and put the files on there
  • See here: How to 'chmod' on an NTFS ( or FAT32 ) partition?
