site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com I saw your message on the boost list, but since I think it's a bug in GCC, not in Boost, I'll reply here. The CVS sources of the boost framework work around this by using an #ifdef to use static versions of the required symbols instead of an anonymous namespace. It would seem as if gcc doesn't coalesce multiple instantiations of templates what are explicitly instantiated inside an anonymous namespace. At least, that's what's happening with boost. I'm not sure how to reproduce this problem without boost, but it drives me nuts when I have to compile our PC team's code which relies on boost. I'd report it to the FSF if I knew where how. Perhaps I'll write a bug in Apple's bugtracker that shows how to reproduce the issue using boost. I'd suggest you do the same, since I may forget ( I'm on vacation :-) ) In the mean time, try using the CVS version of 1.33.1, which includes a workaround. If that's not possible, edit the file boost/bind/placeholders.hpp line 28 to: #if defined(__BORLANDC__) || defined(__GCC__) or #if defined(__BORLANDC__) || defined(__APPLE__) Ryan On Dec 28, 2005, at 12:03 PM, darwin-dev-request(a)lists.apple.com wrote: The loader is complaining that some object files have multiply defined symbols, even though the symbol in question is defined inside an unnamed (anonymous) namespace and thus should be local to the translation unit by the C++ standard.

Disabling cdrom drive caching

They will be ignored. Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… Is there a way to disable the cdrom drive's hardware cache? I know using the raw disk nodes disables the filesystem cache, but I want no caching at all. I was unable to find any documentation on this, but I wasn't sure if there was some ioctl I missed.
