[lfs-support] LFS7.8 chapter 6.7: /tools/bin/gcc file doesnt exist error

[Mohamed Dawod]

Hi,

I found the solution for my problem :
------------------------------------------------

*As for why this occurs, the most common cause is forgetting to remove the
** package source and/or build directories after each build. Check your
** command history for the lfs user to verify, and you have not removed the
** source or build directories after each build, you will need to make sure
** to remember to do so next time.*

-----------------------------------------------
But my question now is (Why can *"forgetting to remove the package source
and/or build directories" cause* such problem ?)
I think it's just directories had been used and have no effect after that!

Thank you in advance.
