Thanks Greg, appreciate the pointer. Another solution is to modify the
gcc build instructions (pass1 at least, will confirm pass 2 later, but
ld LIB_PATH change likely means no change needed) as follows. The
method below requires only unpacking gmp\mpfr once, but thats a fairly
minor point. More importantly, we can include a note about use of
LD_LIBRARY_PATH\ld.so.conf when referencing libs installed in
"non-standard" directories, which increases educational value - the
editors can decide as they wish ;)
1. Move gmp\mpfr instructions to before gcc pass 1
2. Add --with-gmp=/tools to mpfr configure line
3. modify gcc configure line to include --wth-gmp=/tools (--with-mpfr
is not necessary, configure uses gmp location by default)
4. Modify gcc make command with one of the following
LD_LIBRARY_PATH=/tools/lib:$LD_LIBRARY_PATH make
or
cat >> /etc/ld.so.conf << "EOF"
/tools/lib
EOF
make
sed -i -e '@/tools/[EMAIL PROTECTED]' /etc/ld.so.conf
