BUG: gcc41 build failure on Mac OS X 10.3.9

[roland@…]

GCC 4.1 fails to build on Panther (Mac OS X 10.3.9, because of libstdc++ needing a 'nm' command accepting the '-P' (--portability) option. However, Mac OS X 10.3.9 (or perhaps the latest Xcode released for Panther) is shipped with a 'nm' that does not understand this option.

The culprit is libstdc++-v3/scripts/make_exports.pl, which uses NM_FOR_TARGET, whose default value is 'nm'. The odcctools package provides a replacement for nm, /opt/local/bin/odnm, which accepts '-P', and works as expected. I used the following command to solve this build issue:

sed "s/my \$nm = \$ENV{'NM_FOR_TARGET'} || \"nm\";/my \$nm = \"odnm\";/" \
  libstdc++-v3/scripts/make_exports.pl

but I think the following patch should do as well:

Patch to Portfile

[ansgar@…]

The configure script accepts the environment variable NM, so I'd propose to use that (see attached patch). I've successfully compiled gcc41 with that change.

[julien-mac@…]

i've tested gcc41.diff which correct the above problem, but i still have problems after that. during compilation:

panther, closing

[ryandesign (Ryan Carsten Schmidt)]

Replying to toby@…:

panther, closing

Not a good reason for closing a bug.

[ryandesign (Ryan Carsten Schmidt)]

I don't see this problem on Panther; I see the problem in #11890.

[ryandesign (Ryan Carsten Schmidt)]

That is to say, I don't see this problem because I'm not using odcctools because odcctools doesn't build on Panther anymore.

[(none)]

Milestone Port Bugs deleted

[tobypeterson]

Closing again. We don't support Panther, and there obviously isn't anything being done about this bug. Given that we have about 1500 more open tickets than we can deal with, I believe this a reasonable course of action.
