You start with, say, a Linux system. Put the sources there and use the Linux compiler - gcc to compile the sources. You should start with the compiler suite itself, (some) standard libraries, the linker, etc.. This is what hicksd8 means by "toolchain". Now you have a SysV-C-compiler that is compiled fo Linux. This is called "seeding", because ideally a compiler should be able to compile its own sources. That is: when you write a C-compiler in C you write it, then take another C-compiler and compile it, take that executable and use it to compile it again the original sources, then use that executable to compile it again. You then have a code that is compiled by the executable resulting from the very code its source has produced. From then on you use (the compiled) version X-1 to compile version X, etc.. Here you do basically the same for the whole OS.

Of course you build from scratch. You start with the sources for the OS and you want to have a compiled, running and installed OS. That is as much "from scratch" as it can get.

I hope this helps.

freealut-config

freealut-config(1)					      General Commands Manual						freealut-config(1)

NAME

       freealut-config - script to get information about the installed version of freealut

SYNOPSIS

       freealut-config [ --prefix= DIR] [ --exec-prefix= DIR] [ --version ] [ --libs ] [ --cflags ]

DESCRIPTION

       freealut-config	is  a  tool  that is used to configure and determine the compiler and linker flags that should be used to compile and link
       progams, libraries, and plugins that use freealut.

       The use of freealut-config is deprecated. The more generic tool pkg-config should be used instead.

OPTIONS

       --cflags
	      Print the compiler flags that are necessary to compile a program or library that uses freealut.

       --exec-prefix=DIR
	      If specified, use DIR instead of the installation exec prefix that freealut was  build  with  when  computing  the  output  for  the
	      --cflags and --libs options.  This option must be specified before any of the --cflags and --libs options.

       --libs Print the linker flags that are necessary to link a program or library that uses freealut.

       --prefix=DIR
	      If  specified, use PREFIX instead of the installation prefix that freealut was built with when computing the output for the --cflags
	      and --libs options.  This option is also used for the exec prefix if --exec-prefix was not specified.  This option must be specified
	      before any of the --cflags and --libs options.

       --version
	      Prints the currently installed version of freealut on standard output.

EXAMPLES

       gcc -o main.o $(freealut-config --cflags) -c main.c
	      is how you might use freealut-config to compile a C source file for an executable program.

       gcc -o my_app $(freealut-config --libs) main.o util.o
	      is how you might use freealut-config to link compiled objects into an executable program.

SEE ALSO

       pkg-config(1)

       This manual page was written for sdl-config by Branden Robinson, originally for Progeny Linux Systems, Inc., and the Debian Project. It was
       adapted to freealut by Sam Hocevar.
