Building and Installing Cgreen

Here are your alternatives for installing Cgreen.

Install using your distro package manager

Cgreen is available for [some Linux distros] (https://repology.org/project/cgreen/versions). If you are on one of those you can do

$ sudo apt install cgreen1

or equivalent. Not all distros have an up-to-date version.

Install pre-built binary

There are occassionally pre-built binaries available from the GitHub repo. You can download and install these using an appropriate package manager.

Build from source

Get source and build

Clone the Cgreen repo

$ git clone https://github.com/cgreen-devs/cgreen

or get the source from the same place.

Then build it

$ cd cgreen
$ make

The Makefile is mainly for convenience as Cgreen is actually built using CMake. So you can tweak the build using normal CMake settings.

You can run some tests using

$ make unit
$ make test

NOTE: to also build the dynamically auto-discovering runner cgreen-runner, which make unit uses, you need binutils as per the description in the README.md.

Build options

You also have some extra options available

  • build with static libraries
  • build HTML or PDF documentation

To enable any of these use the CMake graphical user interface (CMakeSetup on Windows or ccmake on UNIX) to turn these options on or off.

Note on CYGWIN: Cygwin is not a WIN32 platform, but it is a DLL-platform where libraries normally goes in the bin directory. Running the self-tests handles this automatically but if you want to use the binaries in the 'build'-tree you can either:

  1. install before running the tests and also set your PATH to include "/usr/local/lib"

  2. setting the PATH to include the build directory where the libraries are there is a sh-compatible command script to do that for you. From the top of the Cgreen source directory do:

    . cygwin-setup.sh

Use directly

You can use Cgreen from the source tree without actually installing. Just set your compilation includes to include <path_to_cgreen>/include and link with the built library by pointing the linker to <path_to_cgreen>/build/src/ and use -lcgreen. E.g.

$ cc ... -I/home/me/cgreen/include ...
$ cc ... -L/home/me/cgreen/build/src -lcgreen ...

Install

You can also install Cgreen with

$ make install

which will install Cgreen in what CMake considers standard locations for your environment. Assuming that is /usr/local you should now be able to compile and link using

$ cc ... -I/usr/local/include ...
$ cc ... -L/usr/local/lib -lcgreen ...
