SQLite

Hi all, Should SQLite be added to BLFS? It is a small, compact, very fast, widely-supported, award-winning damn-good SQL engine. Installation is clean, even with GCC-4, though there are some things that deserve mention. 1. It doesn't like to be built in the source tree (think GCC or Glibc). 2. I

Successful First Install - GCC-4.0.1

Went pretty smoothly and completed in less than 24 hours despite recompiling gcc a number of times to play with different C/CXX flag settings. No matter what I tried I got errors on the math tests and ended up with -march=ahtIon-xp -O2 -pipe. I did note that a couple of packages were in *.bz2 form

optimization for lfs-book (6.5 Creating Directories)

Just a little change that is easier to type and also shows a new feature in bash-3.0 (so I think it would be nice to use it): In "6.5. Creating Directories": Instead of typing "install -d /usr/share/man/man{1,2,3,4,5,6,7,8}" the same thing could be done with
