-If you use GCC 5 or higher on Linux, please do not use our LLVM package, but get
-the package for your distribution. Our LLVM package is compiled with GCC 4, so
-you get linking errors, because GCC 5 is using a C++ 11 conforming string
-implementation, which is not used by GCC 4. To sum it up, do not mix GCC 5 and
-GCC 4 binaries. On Ubuntu, you can download the package from
-http://apt.llvm.org/ with:
-
-   wget -O - http://apt.llvm.org/llvm-snapshot.gpg.key | sudo apt-key add -
-   sudo apt-add-repository "deb http://apt.llvm.org/`lsb_release -cs`/ llvm-toolchain-`lsb_release -cs`-8.0 main"
-   sudo apt-get update
-   sudo apt-get install llvm-8.0 libclang-8.0-dev

-to download the package from http://apt.llvm.org/.
