Hello,
I am working though Chapter 6 in Hardened Linux From Scratch - Version
SVN-20060510 and I ran into a strange problem when I try to make gcc.
if [ -f stmp-dirs ]; then true; else touch stmp-dirs; fi
make[2]: Leaving directory `/tools/gcc-build/gcc'
make[1]: Leaving directory `/tools/gcc-build/gcc'
Checking multilib configuration...
multilib.out is unchanged
Configuring in /libstdc++-v3
configure: error: cannot find sources (src/ios.cc) in ../../../gcc-3.4.5/libstdc
++-v3
make: *** [configure-target-libstdc++-v3] Error 1
Now I am pretty new to Linux so I apologize if the answer might seem obvious to
some people, but why is the configure trying to go back 3 levels of
directories to
find the source?
If it goes back 3 levels from /tools/gcc-3.4.5/libstdc++-v3 would that
not try and find
the source in '/gcc-3.4.5/libstdc++-v3/src'? I found the section in
the libstdc++
configure file that does the test, but I didn't really understand what
I needed to change to only go back 2 directories when testing if the
source is present.
Could anyone point me in the Right direction? google returned 0 results.
Thanks for your time!

I'm really sorry to reply to my own message so quickly. I should have
made sure I was finished before I hit send. According to the comments
in the configure, it looks like it tries to find it in the current
directory, then goes up a directory and check there. This is probably
why it makes it all the way to the / directory before failing. I think
the better question would be, "why does it not find src/ios.cc in the
current directory?" I verified that is is infact there. Here is the
test routine in the configure script:
if test -z "$srcdir"; then
ac_srcdir_defaulted=yes
# Try the directory containing this script, then its parent.
ac_confdir=`(dirname "$0") 2>/dev/null ||
$as_expr X"$0" : 'X\(.*[^/]\)//*[^/][^/]*/*$' \| \
X"$0" : 'X\(//\)[^/]' \| \
X"$0" : 'X\(//\)$' \| \
X"$0" : 'X\(/\)' \| \
. : '\(.\)' 2>/dev/null ||
echo X"$0" |
sed '/^X\(.*[^/]\)\/\/*[^/][^/]*\/*$/{ s//\1/; q; }
/^X\(\/\/\)[^/].*/{ s//\1/; q; }
/^X\(\/\/\)$/{ s//\1/; q; }
/^X\(\/\).*/{ s//\1/; q; }
s/.*/./; q'`
srcdir=$ac_confdir
if test ! -r $srcdir/$ac_unique_file; then
srcdir=..
fi
else
ac_srcdir_defaulted=no
fi
if test ! -r $srcdir/$ac_unique_file; then
if test "$ac_srcdir_defaulted" = yes; then
{ echo "$as_me: error: cannot find sources ($ac_unique_file) in $ac_confdir$
{ (exit 1); exit 1; }; }
else
{ echo "$as_me: error: cannot find sources ($ac_unique_file) in $srcdir" >&2
{ (exit 1); exit 1; }; }
fi
fi
(cd $srcdir && test -r ./$ac_unique_file) 2>/dev/null ||
{ echo "$as_me: error: sources are in $srcdir, but \`cd $srcdir' does not wor$
