I know that there are similar questions for installation of clang-lower versions. But, I am trying to follow them to install clang-3.9 or 4.0 , but I am unable to do so on my Linux Mint 18.

First, I was only getting options upto clang-3.8 using

sudo apt-get install clang

followed by pressing tab twice.

Then, I followed this link and followed whatever is there in the first answer.

Now, I can see clang-3.9 and clang-4.0 when I press tab after typing sudo apt-get install clang.

Now, when I do

sudo apt-get install clang-4.0

I get the following error:-

 The following packages have unmet dependencies:
 clang-4.0 : Depends: libjsoncpp0 (>= 0.6.0~rc2) but it is not installable
E: Unable to correct problems, you have held broken packages.

Your version of Mint is based on Ubuntu 16.04, so you should use the sources for that (as documented on the repository's main page):

deb http://apt.llvm.org/xenial/ llvm-toolchain-xenial main
deb-src http://apt.llvm.org/xenial/ llvm-toolchain-xenial main
# 3.8
deb http://apt.llvm.org/xenial/ llvm-toolchain-xenial-3.8 main
deb-src http://apt.llvm.org/xenial/ llvm-toolchain-xenial-3.8 main
# 3.9
deb http://apt.llvm.org/xenial/ llvm-toolchain-xenial-3.9 main
deb-src http://apt.llvm.org/xenial/ llvm-toolchain-xenial-3.9 main

You shouldn't need the ubuntu-toolchain-r/test PPA.

  • Now, I have replaced the lines in the sources.txt file with the ones you mentioned. But, now I am getting another error similar to the previous one, but now it says :- > The following packages have unmet dependencies: > clang-4.0:i386 : Depends: binutils:i386 but it is not going to be installed >E: Unable to correct problems, you have held broken packages. And please forgive my unformatted comment, whenever I am pressing <Enter> , the comment is getting posted. Also tell me if I should edit my question to have a further question like this?

  • Looking at the repositories, it appears that clang-4.0 isn't currently being built for amd64 for some reason. You should be able to install clang-3.9, but you'll have to wait for LLVM to make amd64 binaries available to install clang-4.0. Jan 4, 2017 at 17:08
