Ubuntu – How to Clang static analyzer (scan-build) be installed on Ubuntu 18.04

18.04aptclang

In Ubuntu 16.04, I could:

$ sudo apt install clang
$ scan-build --help
USAGE: scan-build [options] <build command> [build options]
...

But in Ubuntu 18.04, after installing clang, the scan-build executable is not installed.

How can I use apt to install the Clang static analyzer on Ubuntu 18.04?

Best Answer

Based on a search at packages.ubuntu.com, it appears that scan-build has been split into a separate clang-tools package.

More precisely, clang is a dependency package that, on 18.04, installs clang-6.0, while clang-tools depends on the corresponding clang-tools-6.0 - which is the actual package that provides scan-tools for the current version of clang.

Ubuntu – How to install clang 3.9 on Ubuntu 12.04

It seems you can install clang 3.9 on Ubuntu 12.04.

1 - You need to add these repository to your sources.list file.

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

2- Then you need to add ubuntu-toolchain-r/test ppa. Because it provides updated libstdc++ required by clang 3.9

sudo add-apt-repository ppa:ubuntu-toolchain-r/test

3 - Now update the repository index

sudo apt-get update

4 - You should now be able to install clang 3.9

sudo apt-get install clang-3.9

Ubuntu – Installing clang 5.0 and using C++17

Install clang-5 from llvm.org repositores

First, we should add the llvm.org repositories to our sources lists, the line that we should add is:

deb http://apt.llvm.org/xenial/ llvm-toolchain-xenial-5.0 main

Open nano and add the above line to this file:

sudo nano /etc/apt/sources.list.d/llvm.list

Add the repository key, it will make apt able to verify the downloaded packages.

 wget -O - http://apt.llvm.org/llvm-snapshot.gpg.key | sudo apt-key add -

After that, update your lists:

sudo apt-get update

Then install clang-5:

sudo apt-get install clang-5.0 lldb-5.0 lld-5.0

It should work.

If you want to get a list of all available packages from this newly added repository:

grep -i package: /var/lib/apt/lists/apt.llvm* | cut -f3 -d: | sort | uniq

It will give you a list like:

clang-5.0 
clang-5.0-doc 
clang-5.0-examples 
libclang-common-5.0-dev
...

You can then install whatever of them you want.

It may help your compile problem

The header file that has been mentioned does not exist in your error: stdarg.h is a part of libstdc++-5-dev package.

I've got this package on my machine, so if I run:

aptitude why libstdc++-5-dev

I will get:

i   build-essential Depends g++ (>= 4:5.2)                            
i A g++             Depends g++-5 (>= 5.3.1-3~)                       
i A g++-5           Depends libstdc++-5-dev (= 5.4.0-6ubuntu1~16.04.4)

So it seems that installing the build-essential package should solve this error of yours, cause I'm not sure what you've done.
