What is the RBuild ?

RBuild is a Linux kernel kbuild like software configure/build system written by Ruby language. It's small, simple, easy to use and even powerful !

Project host:

http://www.sourceforge.net/projects/rbuild/

How does RBuild work ?

RBuild take the 'RConfig' files as it's input, exports C/C++ header files, Makefiles or others by plug-ins.

RConfig files ===> RBuild ===> C/C++ header, Makefiles ....

How to use RBuild ?

Step 1: create your RConfig file. RConfig file's syntax is inherited from Linux kernel's KConfig.

example:

#
# RConfig file for ubase 4 kernel
#
gen_c_header 'config.h' # generate c header file
title "Welcom to uBase 4 kernel configuration system !"

menu "Kernel schedule configuration" do
    group "Kernel context switch hooks" do
        config :SWITCH_CONTEXT_HOOK_IN do
            bool "context switch in hook"
        end
        config :SWITCH_CONTEXT_HOOK_OUT do
            bool "context switch out hook"
        end
    end
end

menu "ARCH and CPU configuration" do
    choice :ARCH, "Choice CPU core" do
        # default :ARCH_ARM
        config :ARCH_ARM do
            bool "ARM core"
        end
        config :ARCH_MIPS do
            bool "MIPS core"
        end
    end

    choice :CPU, "Choice CPU" do
        depends :ARCH # need to select 'ARCH' before select 'CPU'

        config :CPU_EP7XXX do
            bool "Cirrus Logic EP7xxx CPU"
            depends :ARCH_ARM
        end
        config :CPU_PXA27X do
            bool "Intel XScale PXA27x CPU"
            depends :ARCH_ARM
        end
    end
end

choice :BSP, "Platform" do
    depends :CPU # need to select 'CPU' before select 'BSP'

    config :PT8XX do
        bool "PT8XX"
        depends :CPU_EP7XXX
    end
    config :PT98X do
        bool "PT98X"
        depends :CPU_PXA27X
    end
end

Step 2: create your rake file :

require 'path_to_rbuild/rbuild'

task :menuconfig do
rconf = RBuild::RConfig.new('RConfig')
rconf.menuconfig()
end

Step 3: start to configure your project !

# rake menuconfig

... do your configuration ....

Press 'X' to export to C/C++ header file, press 'Q' to quit.

now check your config header file:

# cat config.h

Wow, Done !
