Well considering the binutils version is also mentioned as part of the prerequisites for GCC with a newish version; I think mentioning it also (which might get out of sync) in libstdc++ manual a little over board. See https://gcc.gnu.org/install/prerequisites.html .

Looks like most of the versions mentioned in https://gcc.gnu.org/install/specific.html need to be updated to at least the version that was mentioned in libstdc++'s manual. hppa*-hp-hpux11, i?86-*-linux*, and sparc-sun-solaris2* all mention versions older than 2.15.9. At least https://gcc.gnu.org/install/prerequisites.html recommends 2.35+ (due to LTO requirements).

If there was a more recent minimum version, it would be documented there. So your suggestion would mean not removing it. Bumping it to another version wouldn't make sense if 2.15.90.xxx is still the minimum. If the main GCC installation docs specify a more recent minimum, then saying anything in the libstdc++ docs is either redundant, incorrect, or not the right place to document it. > > Okay? > > > > Gerald > > > > > > libstdc++-v3: > > * doc/xml/manual/prerequisites.xml: Remove note from the GCC > 4.0.1 > > days. > > * doc/html/manual/setup.html: Regenerate. > > > > diff --git a/libstdc++-v3/doc/html/manual/setup.html > b/libstdc++-v3/doc/html/manual/setup.html > > index 78d2a00c50a..d8c5ff65cff 100644 > > --- a/libstdc++-v3/doc/html/manual/setup.html > > +++ b/libstdc++-v3/doc/html/manual/setup.html > > @@ -29,10 +29,7 @@ > > the tools you will need if you wish to modify the source. > > </p><p> > > Additional data is given here only where it applies to libstdc++. > > - </p><p>As of GCC 4.0.1 the minimum version of binutils required to > build > > - libstdc++ is <code class="code">2.15.90.0.1.1</code>. > > - Older releases of libstdc++ do not require such a recent version, > > - but to take full advantage of useful space-saving features and > > + </p><p>To take full advantage of useful space-saving features and > > bug-fixes you should use a recent binutils whenever possible. > > The configure process will automatically detect and use these > > features if the underlying support is present. > > diff --git a/libstdc++-v3/doc/xml/manual/prerequisites.xml > b/libstdc++-v3/doc/xml/manual/prerequisites.xml > > index a3c6e732a77..0efe63bcd46 100644 > > --- a/libstdc++-v3/doc/xml/manual/prerequisites.xml > > +++ b/libstdc++-v3/doc/xml/manual/prerequisites.xml > > @@ -25,10 +25,7 @@ > > Additional data is given here only where it applies to libstdc++. > > </para> > > > > - <para>As of GCC 4.0.1 the minimum version of binutils required to > build > > - libstdc++ is <code>2.15.90.0.1.1</code>. > > - Older releases of libstdc++ do not require such a recent version, > > - but to take full advantage of useful space-saving features and > > + <para>To take full advantage of useful space-saving features and > > bug-fixes you should use a recent binutils whenever possible. > > The configure process will automatically detect and use these > > features if the underlying support is present. >
