Re: Safe reversion to older version of C compiler

Hi, check out the utility that ought to have been installed (at least when you have the Mac Dev Tools installed) called gcc_select.

Here's a short snippet from it's man page:

GCC_SELECT(8)         MacOS X      GCC_SELECT(8)

SYNOPSIS
       gcc_select -- Switch the default system compiler

USAGE
         gcc_select [-n] [-force] [2 | 3 | 3.<number> | 4.<number> ]
        [-h | --help] [-v | --version] [-l | --list] [-root]

       o   2: Select gcc 2.95.2 as the default compiler.

       o   3: Select gcc 3.1 as the default compiler.

       o   3.x: Select gcc 3.x as the default compiler.

       o   4.x: Select gcc 4.x as the default compiler.

Thanks for your response! After my OP, I pulled the coat of Parrot hacker Coke to it. We discussed it a bit on #parrot and he advised me to first (do no harm) and try running Parrot's Configure.pl script with some shell variables re-set. Incorporating an earlier suggestion from Parrot hacker particle, this is what I came up with: `#!/bin/sh CC="/usr/bin/gcc-3.3" CX="/usr/bin/g++-3.3" /usr/local/bin/perl Configure.pl --cc="$CC" --cxx="$CX" --link="$CX" - +-ld="$CX" --without-icu --without-gmp $@` [download] ... which kinda does what gcc_select would do. This script resulted in a Parrot configuration which you can see here. make ran without a hitch! And make test (probably as a result of yesterday's on-line Parrot Bug Day) ran with only 1 failing test -- down from 62 the last time I tried that a couple of weeks ago. Jim Keenan	[reply] [d/l]

I'm glad you got it working one way or another. Too bad I had to miss the hackathon in (greater) Chicago in November (due to some scheduling conflicts). Maybe I could've helped eliminate your frustration a little earlier :) I don't recall where/why/how I first read about the `gcc_select` utility, but I suppose it's good that it's recorded above for anyone else who might be looking for it :) --chargrill `s*lil; $=join'',sort split q; s;.;grr; &&s+(.(.)).+$2$1+; $; = qq-$_-;s,.,ahc,;$,.=chop for split q,,,reverse;print for($,,$;,$,$/)` [download]	[reply] [d/l] [select]
