Hello all,

I just wanna make clear one important thing.

on the lfs book,at chapter 5.1,it is mentioned that we have to delete both the source directory and build directory after installing each package,to avoid mis-configurations.

Here, does the source directory refers to the actual zipped source file (e.g., binutils-2.17.tar.bz2) or the extracted source file (e.g., binutils-2.17)..?

please guide me..

thanks in advance..

You need to delete the directory/directories.

After untarring, for example binutils-2.17.tar.bz2 you have a binutils-2.17 directory and during the build you create a binutils-build directory.

The book is talking about binutils-2.17 and binutils-build. Not all packages use a build directory, so most often you only have to delete 1 directory.

Got it,Drunna..

Thanks again..

Then why are e=we extracting and building it if we are deleting it?
I fell like I am missing something here. Why are we building it and deleting it?!

These are not the final installed packages, they are just where they are built, they will be installed into $LFS/tools Ch5 and Ch6 installed as the final build of system.

You have to untar the tarball cd into dir do what the book sayes. Then return to sources dir, and rm the dir which you have just built, reason for this is so that the next time you build the package it is afresh untarrred package, also if a package is looking for something it dosn't get confused with previous dir.
Also if a package fails to build you should remove it and untar again.

Once you have installed a package (even if it's just a temporary version in the /tools tree), you don't need the source directory any more. Everything useful in it has been copied over, so you can always delete it. If you need it again, you can recreate it by unpacking the original tarball (which you don't delete!).

In LFS, deleting the source directory as soon as you have completed the installation is particularly important because many packages are built more that once (once or even twice for the tools stage and once for the final system). You must not have any stale files from previous builds left over when you do this.

I agree with spiky that you should also do this automatically if a build fails for any reason. Don't mess about with "make clean", it's not reliable. Just delete the whole directory with its contents and unpack the source tarball afresh.
