I noted that issue at least as far back as <http://gcc.gnu.org/ml/gcc/2001-06/msg00807.html>. I'd still prefer all these options to be listed directly in the main installation manual, as I indicated in <http://gcc.gnu.org/ml/gcc-patches/2001-07/msg00564.html>, and indeed for the separate subcomponent installation manuals to go away. > fear other libraries have similar problems: I've already printed the > output of configure --help for all in-tree configure scripts and plan > to check them against the installation guide.

You'll need to check for $enable_ and $with_ variables the scripts (including config.gcc etc.) are checking directly to find those. Making them proper configure options that show up in --help would be a good idea, I think. > ** it is highly inconsistent, like commands write with and without > quotes, same for target triplets.

I'm not sure the cross-compile install concepts are explained elsewhere in the manual. But see PR 5301; everyone uses or produces a script working for their use cases, rather than documentation, and probably no-one actually knows general rules covering every possible use case. The list of short names for particular systems is old and pretty useless (actually, I'd rather config.sub ceased to support so many variants). Current lists of CPUs and OSes might be useful, but my preference would be for install.texi to list all supported triplets rather than fragments of them. The *-local support should probably be removed, and the documentation removed with it. -- Joseph S. Myers jos...@codesourcery.com
