In this chapter we enter the building site, and start constructing our LFS system in earnest. That is, we chroot into our temporary mini Linux system, create some auxiliary things, and then start installing all the packages, one by one. The installation of all the software is pretty straightforward, and you will probably think it would be so much easier and shorter to give the generic installation instructions for a package here and only explain in full the installation of those packages that require an alternate method. Although we agree with that, we choose to give the full instructions for each and every package, simply to avoid any possible confusion and errors. If you plan to use compiler optimization for the packages installed in this chapter, take a look at the optimization hint at . Compiler optimization can make a program run faster, but may also cause compilation problems. If you run into problems when using optimization, always try it without optimization to see if the problem persists. Please refrain from installing more than one package at a time, even if it may save you time (especially with dual CPU machines). If you install the wrong package at the wrong time, it may hard-wire program paths to $LFS/static which will cause the programs to stop working once the static directory is removed. The order packages are installed in this chapter have to be followed exactly to be sure nothing is hard-wiring the static paths.
