How do I install Clang Version 3 in 10.10?

  • 772

How would I go about installing version 3 of Clang/LLVM in Ubuntu 10.10? Ubuntu 10.10 installs version 2.8 by default. Version 3 has more extensive/up to date support for C++ and possibly C (I am not totally sure about C). I know that I could possibly compile from source but was wondering if there is a ppa or other method to avoid compiling it from source.

If I compile from source do I have to tell it where to find the std c library etc. or is that automatically done.

    I haven't found a PPA for maverick - you will need a later version of ubuntu to get v3.

    However, to compile is very straightforward. Clang themselves have the instructions well written. A few pointers:

    You will need the following packages to be installed before you compile

    sudo apt-get install build-essential subversion

    Start at the second instruction "2. Checkout LLVM"

    At step 4 there is a mistake - it should read cd ../projects

    I didnt need to specify my C/C++ headers - configure worked this out by itself.

    Word of warning - it takes hours to compile - best to leave this as an overnight job!
