What is the recommended way to install LLVM 3.8 on Ubuntu 14.04? The generic apt-get thinks 3.4 is the latest version. I found instructions at http://llvm.org/apt/ but they don’t work; deb and deb-src are not recognised commands, and the suggested apt-get variants are unable to locate the package.
You want to look at the apt-add-repository command, basically you provide that command like:
- sudo add-apt-repository ‘deb llvm-toolchain-trusty-3.8 main’
- sudo apt-get update
- sudo apt-get install clang-3.8

Still doesn’t work:
a@a-VirtualBox:~$ sudo add-apt-repository ‘deb http://llvm.org/apt/trusty/ llvm-toolchain-trusty-3.8 main’
a@a-VirtualBox:~$ sudo apt-get update

Install from source. I built LLVM+clang+LLDB last night on my Ubuntu 14.04 system. It just works.
I managed to get some time to have a look at this on a clean VM, and yup - the llvm 3.8 folder is missing from the server. It seems you can get the 3.8 packages if you use the ‘deb llvm-toolchain-trusty main’ line though. Can someone who maintains the LLVM apt repos have a look at this? I think that the 3.8 folder needs to be restored with the LLVM 3.8 release. Cheers, -Neil.
