gcc build instructions have syntax error

[miland]

on page:

​http://www.linuxfromscratch.org/lfs/view/stable/chapter05/gcc-pass1.html

an option is given like --disable-libstdc++v3

it should be --disable-libstdcxx

You are right, but it doesn't seem to hurt anything and we build gcc again 4 packages later. Will fix in svn though.

Please test before changing it: last time I tried to use --disable-libstdcxx, I got an error when running make. --disable-libstdc++v3 gives no error. Will investigate more so that we know what to answer to this ticket...

[Pierre Labastie]

I think there is an error in configure:

# Check whether --enable-libstdcxx was given.
if test "${enable_libstdcxx+set}" = set; then :
  enableval=$enable_libstdcxx; ENABLE_LIBSTDCXX=$enableval
else
  ENABLE_LIBSTDCXX=default
fi

if test "${ENABLE_LIBSTDCXX}" = "no" ; then
  noconfigdirs="$noconfigdirs libstdc++-v3"
fi

but everywhere else, the configdir is referenced as target-libstdc++-v3.

Applying the sed:

sed -i -e 's/\(dirs\) \(libstdc\)/\1 target-\2/' configure

and changing --disable-libstdc++-v3 to disable-libstdcxx generates exactly the same Makefiles (apart from the configargs variables) as when using --disable-libstdc++-v3 and no sed.

Will report upstream. Meanwhile, I guess it is OK to use the current switches for gcc-pass1.

[bdubbs@…]

We could do:

sed -i -r 's/(disable-libstdc)xx/\1++-v3/' configure

as that just changes the --help output, but we won't do that. We'll just leave things as they are.
