Hello Bruce,
In the past, people who have included gcc-build within gcc-<x.y.z> ended
up having errors in the build process from building within the gcc source
tree. Since you tested that with ch5, then ch6 should be okay. I suppose
it depends on the gcc version. The problem occured many years ago.
We have stuck with this for the longest time:
https://gcc.gnu.org/install/configure.html
"First, we highly recommend that GCC be built into a separate directory
from the sources which does not reside within the source tree. This is how
we generally build GCC; building where srcdir == objdir should still work,
but doesn't get extensive testing; building where objdir is a subdirectory
of srcdir is unsupported."
When I read that, I interpret is to mean that they build for multiple
targets and want to keep the object files from those builds separate.
I've modified LFS according to the attached diff. I did a full build and
the failures in the test logs are the same as with the current book.
Actually I cannot think of a good reason for differentiation between the
case where objdir is completely separate from srcdir and the case where
objdir is a subdirectory of srcdir, even though they say that case is
unsupported. About the only thing I can think of is that they may be
doing some kind of recursive directory search and there is some sort of
match in the build tree.
In any case, my initial test shows a normal build.
Still asking for more input before I commit.
