Building kcov From Source

As of this writing, the recommended way to get kcov is to build from upstream sources from GitHub. Ubuntu Xenial (for example) has packaged versions, but they have known problems not evident when using upstream.

Ubuntu-only Preparation

On Ubuntu, install the build dependencies:

sudo apt install binutils-dev libdw-dev libelf-dev libiberty-dev

macOS and Ubuntu Build Steps

To build from source, follow these steps:

git clone git@github.com:SimonKagstrom/kcov.git
cd kcov
mkdir build
cd build
cmake ..
cmake --build .

The resulting binary will be in kcov/build/src/kcov. Create a symbolic link to the binary from some directory on your $PATH.

macOS Run-time Requirements

On macOS, be sure that your account has developer mode enabled, which gives you the privileges necessary to run debuggers and similar tools. If you are an administrator, use this command:

sudo /usr/sbin/DevToolsSecurity --enable
