The GnuCash project uses several different tools to build the program, the docs, and OS specific packages.
Basic Tools
These control the build process at a low level.
Make
Make is a build automation tool that builds targets from source by interpreting recipe files called Makefiles which specify how to transform the source file(s) into the target file(s). Many "Integrated Development Environments" or "IDEs" use make (or its Microsoft cousin nmake) to perform the build.
Makefiles can be written by hand (as is the case for gnucash-htdocs.git) or generated by Autotools or CMake.
Ninja
Ninja is a small build system with a focus on speed. It is designed to have its input files generated by a higher-level build system, and it is designed to run builds as fast as possible.
- Note
- The commands change then from
make [target]toninja [target]. - Note
- Some Linux distributions name the command
ninja-buildto distinguish it from another program calledninja.
CMake is commonly used to build ninja build files: To do so pass -G Ninja among the cmake arguments.
Tool Chains
In addition, GnuCash uses different tool chains to control the basic tools mentioned above. The program makes use of the CMake tool chain, while the documentation uses the Autotools tool chain. The website is compiled directly using Make.
CMake
To build the program, we use CMake.It is a cross-platform free and open-source software application for managing the build process of software using a compiler-independent method. It supports directory hierarchies and applications that depend on multiple libraries. It is used in conjunction with native build environments such as make, Apple's Xcode, and Microsoft Visual Studio. It has minimal dependencies, requiring only a C++ compiler on its own build system.
Autotools
To build the Gnucash-docs, we use the GNU Build System, often referred to as "autotools". It's a complex and capable system for configuring and building a wide range of projects on a wide range of platforms. The Autotools Mythbuster provides an excellent tutorial and reference for those wishing to learn about creating and building projects using the system.
For those who simply need to build the documentation from source, the following three commands will suffice:
autogen.sh: Checks that all required parts of the build system are installed, then builds theconfigureprogram from its source,configure.acand the intermediate MakefilesMakefile.infrom their sourceMakefile.am. You'll runautogen.shafter you first clonegnucash-docs.git, any time you edit aMakefile.amorconfigure.ac, and any time you pull commits with changes to those files. Since it does no harm to run it unnecessarily we recommend that you run it after anygit pull.configure: This shell script, generated byautogen.shas described above, examines your system and its arguments to convert the intermediateMakefile.in<code> to <code>Makefilethat themakecommand will use to actually generate the documentation product files. One can get a listing of the arguments and environment variables that any particularconfigureunderstands by runningconfigure --help.make: UsingMakefileas a template,makeruns the various programs and scripts needed to perform the build. Its arguments are the targets to be built; there are two special targets,checkruns tests to ensure that the project has been built correctly andinstallmoves the build products to the locations from which they may be used.
