Hello, With regards to the re-compiling of gcc, I have not done that for quite some time now. From memory, I stopped doing it because I ran into issues with compiling other packages in blfs. What I now do, is modify the LFS book's chapter on gcc and add all the optional languages apart from ADA, as I have not found a package that I use that needs it. Then I allow jhalfs to run and install LFS. By modifying the xml page of the book, and then allowing jhalfs to do the command extraction, I have not come across the issues with files not found. I find it a lot easier to just create bash scripts to install blfs. I know that jhalfs is well maintained, but as it states when you go to use it on blfs, that book's commands are just too complex for some packages to correctly extract them. I got a headache just by looking at the extracted scripts when it came to blfs, so either just manually compiled or used scripts. It does take a while to make the scripts, but once completed you have them to use with all the options that you want in them. Either burn your scripts to cd/dvd or upload them to a cloud storage service and that way you will not loose them if you do a bare installation.
