I ran ./configure, but when I try to make llvm, I get the following error:

P.S. I tried installing it by following these instructions - Getting Started: Building and Running Clang

    What version are you trying to build? is there a particular reason you are trying to install from source rather than using the version provided in the package repository? – steeldriver Sep 12 '15 at 12:50
  • Honestly, I am new to Linux and the source way showed up when I googled how to install clang. May you tell me with a bit more details what the other way to do it would be? I just followed the tutorial, I may only assume it is the latest version. – frostblooded Sep 12 '15 at 12:51
  • Unless you need particular features that are not supported by the packaged version (which is clang-3.4 in 14.04), I'd recommend that you stick with that - at least for now. You should be able to install it just like any other package i.e. from Software Center or from a terminal using sudo apt-get install clang. – steeldriver Sep 12 '15 at 12:55

I had the same problem and it was solved by installing a newer version of gcc, which is basically an answer in this thread: How do I use the latest GCC on Ubuntu?

I guess a newer version of Ubuntu (15) automatically solves this problem because the default gcc there is 4.9 already.

I had the same problem, I fixed it by clearing the CMake cache. Just delete CMakeCache.txt and try running make again. CMakeCache.txt should be in the same directory you're trying to execute the CMake command in.

  • I edited the answer for clarity. I also had the uint64_t not defined error, I fixed it by clearing the CMake cache. – Adam Mar 06 '17 at 22:56
