They are set for these builds only. If you were expected to put them in your 
.bashrc file, you would have been told to do this in chapter 4.

The reason they are required here in the second pass is that you are no longer 
cross-compiling. Consequently the configuration script will expect build tools 
to have normal short names. Until you have completed pass 2, the only tools 
with such names are the ones on your host.

But you want to use the cross-compiled tools you have made in pass 1, and they 
have long names incorporating the architecture they were built for. So you must 
tell the script explicitly to use those tools.

In those two builds, the three variables are passed to the configure
script.  The line continuations ('\') mean that this is all one long
command, so those variable settings are only in effect when
configure is run.

I'm very sorry. Please disregard my question above.
I figured it out now.

Does the book say to set them permanently?  Don't read things into the 
instructions that are not there.

[lfs-support] Question about variables in the terminal

Hi,

Sorry if I'm bothering everyone too much lately. I just have a short
question this time. I continued on in the book and it says to set
the variables CC, AR, and RANLIB. So I'm wondering whether that is a
one time thing (just for that compilation) or should I add them to my
.bashrc file? I wonder because the book doesn't make it clear. It
says to set those variables before compiling binutils pass 2 and then
again before compiling gcc pass 2. So it sounds like they don't need
to be permanent. But does the book mean that they should be
permanent/set before each build? Or does it mean that they should
only be set for binutils and gcc pass 2?

Thank you very much,
