Building with ninja

介绍

如前所述，CMake是一个元构建系统，可用于为许多其他构建工具创建构建文件。 这个例子展示了如何让CMake使用ninja构建工具。

生成器

CMake are responsible for writing the input files (e.g. Makefiles) for the underlying build system. Running cmake --help will show the generators available. For cmake v2.8.12.2 the generators supported on my system include: CMakehttps://cmake.org/cmake/help/v3.0/manual/cmake-generators.7.html[generators]负责为基础构建系统编写输入文件（例如Makefile）。 运行cmake --help将显示可用的生成器。 对于cmake v2.8.12.2，我的系统支持的生成器包括：

Generators

The following generators are available on this platform:
  Unix Makefiles              = Generates standard UNIX makefiles.
  Ninja                       = Generates build.ninja files (experimental).
  CodeBlocks - Ninja          = Generates CodeBlocks project files.
  CodeBlocks - Unix Makefiles = Generates CodeBlocks project files.
  Eclipse CDT4 - Ninja        = Generates Eclipse CDT 4.0 project files.
  Eclipse CDT4 - Unix Makefiles
                              = Generates Eclipse CDT 4.0 project files.
  KDevelop3                   = Generates KDevelop 3 project files.
  KDevelop3 - Unix Makefiles  = Generates KDevelop 3 project files.
  Sublime Text 2 - Ninja      = Generates Sublime Text 2 project files.
  Sublime Text 2 - Unix Makefiles
                              = Generates Sublime Text 2 project files.Generators

As specified in this post, CMake includes different types of generators such as Command-Line, IDE, and Extra generators.如本文所指定，CMake包括不同类型的生成器，例如命令行，IDE和其他生成器。

Command-Line Build Tool Generators命令行编译工具生成器

These generators are for command-line build tools, like Make and Ninja. The chosen tool chain must be configured prior to generating the build system with CMake.这些生成器用于命令行构建工具，例如Make和Ninja。 在使用CMake生成构建系统之前，必须先配置所选的工具链。

The supported generators include:支持的生成器包括：

  • Borland Makefiles

  • MSYS Makefiles

  • MinGW Makefiles

  • NMake Makefiles

  • NMake Makefiles JOM

  • Ninja ninja用的

  • Unix Makefiles make用的

  • Watcom WMake

IDE Build Tool Generators

These generators are for Integrated Development Environments that include their own compiler. Examples are Visual Studio and Xcode which include a compiler natively.这些生成器用于自己有编译器的IDE。 示例是Visual Studio和Xcode。

The supported generators include:

  • Visual Studio 6

  • Visual Studio 7

  • Visual Studio 7 .NET 2003

  • Visual Studio 8 2005

  • Visual Studio 9 2008

  • Visual Studio 10 2010

  • Visual Studio 11 2012

  • Visual Studio 12 2013

  • Xcode

Extra Generators

These are generators create a configuration to work with an alternative IDE tool and must be included with either an IDE or Command-Line generator.这些生成器，用于其他IDE工具一起使用的配置，并且必须包含在IDE或命令行生成器中。

The supported generators include:

  • CodeBlocks

  • CodeLite

  • Eclipse CDT4

  • KDevelop3

  • Kate

  • Sublime Text 2

Note

In this example ninja is installed via the command sudo apt-get install ninja-build安装ninja的命令

Calling a Generator

To call a CMake generator you can use the -G command line switch, for example:使用-G参数来唤醒CMake的生成器

cmake .. -G Ninja

After doing the above CMake will generate the required Ninja build files, which can be run from using the ninja command.完成上述操作后，CMake将生成所需的Ninja构建文件，可以使用ninja命令运行该文件

$ cmake .. -G Ninja

$ ls
build.ninja  CMakeCache.txt  CMakeFiles  cmake_install.cmake  rules.ninja

构建示例

Below is sample output from building this example.

$ mkdir build.ninja

$ cd build.ninja/

$ cmake .. -G Ninja
