The following is a HowTo describing the setup of OCLint for any C/C++ project using autotools.

1. OCLint Setup

First step is downloading OCLint, as there are no package so far, it's just extracting the tarball somewhere in $HOME. Check out the latest release link on http://archives.oclint.org/releases/. 
cd
wget "http://archives.oclint.org/releases/0.8/oclint-0.8.1-x86_64-linux-3.13.0-35-generic.tar.gz"
tar zxvf oclint-0.8.1-x86_64-linux-3.13.0-35-generic.tar.gz
This should leave you with a copy of OCLint in ~/oclint-0.8.1

2. Bear Setup

As project usually consist of a lot of source files in different subdirectories it is hard for a linter to know where to look for files. While "cmake" has support for dumping a list of source files it processes during a run "make" doesn't. This is where the "Bear" wrapper comes to play: instead of 
make
you run 
bear make
so "bear" can track all files being compiled. It will dump a JSON file "compile_commands.json" which OCLint can use to do analysis of all files. To setup Bear do the following 
cd
git clone https://github.com/rizsotto/Bear.git
cd Bear
cmake .
make

3. Analyzing Code

Now we have all the tools we need. Let's download some autotools project like Liferea. Before doing code analysis it should be downloaded and build at least once: 
git clone https://github.com/lwindolf/liferea.git
cd liferea
sh autogen.sh
make
Now we collect all code file compilation instructions with bear: 
make clean
bear make
And if this succeed we can start a complete analysis with 
~/oclint-0.8.1/bin/oclint-json-compilation-database
which will run OCLint with the input from "compile_commands.json" produced by "bear". Don't call "oclint" directly as you'd need to pass all compile flags manually. If all went well you could see code analysis lines like those:
