Redux: AUTHOR: William Immendorf DATE: 2008-12-20 LICENSE: Creative Commons Attribution-Noncommercial-Share Alike 3.0 United States License http://creativecommons.org/licenses/by-nc-sa/3.0/us/ SYNOPSIS: Installing all the GCC compilers while building LFS DESCRIPTION: This hint will guide you through the installation of any or all the GCC compilers while building an LFS system. These instructions target the 4.x.x series of GCC as there have been significant changes since the 3.x.x series. Prior to the 4.x.x series, only the Ada compiler could not be installed during Chapter 6 of an LFS build. See Randy's http://www.linuxfromscratch.org/hints/downloads/files/ada_install_during_lfs.txt hint for instructions to install the Ada compiler during an LFS build if you are using a version of GCC prior to 4.x.x. ATTACHMENTS: None REQUIRED DOWNLOADS: 1. The GCC tarball for whatever version of GCC called for in LFS. This will be a file named something similar to gcc-4.3.2.tar.bz2 2. The 2005 version of the GNAT compiler found on the AdaCore site. The download location (https://libre.adacore.com/dynamic/download_page) requires that you create an account on the AdaCore site before you can download the package. Nothing is required other than a valid email address. Ensure you download the 2005 version of the GNAT compiler. The 2006 version will not work. The file name you need is: gnat-gpl-2005-i686-gnu-linux-gnu-libc2.3-bin.tar.gz. (not required if your host system has an existing Ada compiler, or you don't plan on installing the GCC Ada compiler) 3. A Zip tarball if you are building the Java comp. See http://www.info-zip.org/Zip.html#Sources for download locations. 4. An Unzip tarball if you are building the Java comp. See http://www.info-zip.org/UnZip.html#Downloads for download locations.

INTRODUCTION: The default installation during LFS only installs a C and C++ compiler. If you know that you'll need additional compilers after LFS is built, it is easier to just build the additional compilers during LFS. So, you say to yourself, when I get to the GCC installation in Chapter 6 of LFS, I'll just add additional compilers to the configure script command and I'll build them then. This won't work for the Ada, Fortran or Treelang compilers. For these three compilers, you cannot wait until the GCC installation in Chapter 6 to decide you want/need to install them (Fortran is a slight exception to this). At this point of Chapter 6, you are in a chroot environment working with whatever is installed in the /tools directory you created in Chapter 5 and there are not adequate tools, nor any real way to add them, to compile Ada and Treelang. In summary, if you need to install the Ada, Fortran or Treelang compilers during Chapter 6 of an LFS build, you'll need to do some extra work. The Java and Objective C compilers can be installed by simply adding them to the list of compilers in the configure script parameter, --enable-languages=... In order to install the GCC Ada compiler, you must have an existing Ada compiler available so GCC can boostrap its version of Ada. If your host has an existing Ada compiler, you can omit some of this hint and simply use the updated Chapter 5 and Chapter 6 GCC installation instructions. More on this in the appropriate sections later in the hint. = 2. THE TREELANG COMPILER: = You probably don't need the Treelang compiler. It is only good for developers who are developing a new compiler for GCC. However, if you wish to build it during a build of LFS, you'll need to install the Bison and Flex packages before starting the Chapter 6 build of GCC. = 3. THE JAVA COMPILER = gjar, a part of gcj, needs Zip and Unzip to build. Use BLFS instructions for both. 4. THE ADA COMPILER: Starting with version 4.x.x of GCC, the Ada installation is simpler, but it still requires an initial boostrap using an existing Ada compiler. If you have an Ada compiler on the host system you're building LFS on, there isn't much required before you can just build GCC. 5. PACKAGE DEPENDENCIES: As previously mentioned, if you already hav

Additionally, there is no mention of the original author in the acknowledgments section, therefore I'd like the hints maintainer to not post this hint until these items are taken care of.
