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.

g-wrap-config(1)					      General Commands Manual						  g-wrap-config(1)

NAME
g-wrap-config - script to get information about the installed version of G-Wrap SYNOPSIS
g-wrap-config [ --version ] [ --c-compile-args LANG | --c-link-args LANG | --guile-module-directory ] DESCRIPTION
g-wrap-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 G-Wrap. However, since G-Wrap 1.9, this tool has been deprecated in favor of pkg-config(1). New code should use the g-wrap-2.0-guile pkg-config module, g-wrap-config only exists for compatibility reasons. OPTIONS
--c-compile-args LANG Print the compiler flags that are necessary to compile a program or library that uses the G-Wrap language binding for LANG. --c-link-args LANG Print the linker flags that are necessary to link a program that uses the G-Wrap language binding for LANG. --version Prints the currently installed version of G-Wrap on standard output. EXAMPLES
gcc -o main.o $(g-wrap-config --c-compile-args guile) main.c is how you might use g-wrap-config to compile a C source file for an executable program. gcc -o my_app $(g-wrap-config --c-link-args guile) main.o util.o is how you might use g-wrap-config to link compiled objects into an executable program. AUTHOR
G-Wrap has been written by Andreas Rottmann, Rob Browning and Christopher Lee. This manual page was written by Andreas Rottmann, originally for the Debian Project. G-Wrap 1.9 2005-05-01 g-wrap-config(1)
