How to install Infer from source

Pre-compiled clang versions

We provide a source release of Infer packaged with pre-build binaries for clang and facebook-clang-plugins for Linux and MacOS. We encourage you to use this release as compiling clang is time-consuming. Install the dependencies as explained in the next section, then follow the instructions in our Getting Started page to compile and install Infer.

Infer dependencies for MacOSX

Here are the prerequisites to be able to compile Infer on MacOSX. This is required to be able to use the release (faster), or to compile everything from source (see the end of this document).

  • opam 1.2.2 (instructions here)
  • Python 2.7
  • sqlite
  • pkg-config
  • Java (only needed for the Java analysis)
  • cmake (only needed for the C/Objective-C analysis)
  • clang in Xcode command line tools. You can install them with the command xcode-select --install (only needed for the C/Objective-C analysis)
  • Xcode >= 6.1 (only needed for the C/Objective-C analysis)
  • autoconf >= 2.63 and automake >= 1.11.1 (if building from git)

You can install some of these dependencies using Homebrew:

brew install autoconf automake cmake opam pkg-config sqlite
brew cask install java

Infer dependencies for Linux

Here are the prerequisites to be able to compile Infer on Linux. This is required to be able to use the release (faster), or to compile everything from source (see the end of this document).

  • opam 1.2.2
  • Python 2.7
  • pkg-config
  • Java (only needed for the Java analysis)
  • gcc >= 4.7.2 or clang >= 3.1 (only needed for the C/Objective-C analysis)
  • autoconf >= 2.63 and automake >= 1.11.1 (if building from git)

See also the distro-specific instructions for Ubuntu and Debian below.

Install Infer from source

Run the following commands to get Infer up and running:

# Checkout Infer
git clone https://github.com/facebook/infer.git
cd infer
# Compile Infer
./build-infer.sh java
# Install Infer into your PATH
export PATH=`pwd`/infer/bin:$PATH

Replace ./build-infer.sh java with ./build-infer.sh clang to build the C and Objective-C analyzer from source. Beware that this command may take a really long time because it will compile a custom version of clang. This custom version is used by Infer to parse C and Objective-C source code. We encourage you to use a release instead, which ship with clang already compiled.

See ./build-infer.sh --help for more options, eg ./build-infer.sh on its own will build the analyzers for both Java and C/ObjC.

Install Infer from source without opam

If for some reason you prefer to install Infer's OCaml dependencies by some means other than opam, you can still compile Infer by running:

./autogen.sh
./configure # Disable Java or C/C++/ObjC analyzers with --disable-java-analyzers or --disable-c-analyzers
make
# Install Infer into your PATH...
export PATH=`pwd`/infer/bin:$PATH
# ...or, alternatively, install Infer system-wide
sudo make install

How to install the dependencies on Linux

See the Dockerfile in docker/ for inspiration. It includes the dependencies needed to build infer on Debian 9 (stretch).

Setting up opam

Get opam from your distribution, or from the opam website.

The OCaml dependencies needed by Infer are automatically handled by opam when running ./build-infer.sh.
