Hi,
Let me start off by saying that I consider multi_index to be the most
stunningly clever AND useful piece of c++ around. Thanks!
A PowerDNS user on RHEL 3 with a gcc that calls itself 'gcc 3.2.3' reports
the following error compiling PowerDNS snapshot 576
(http://svn.powerdns.com/snapshots/576/pdns-2.9.20.20060311.576.tar.gz):
Message:

make[3]: *** [pdns_recursor.o] Error 1
make[3]: Leaving directory /temp/pdns-2.9.20.20060311.576/pdns'
To reproduce, download the tar file, run ./configure --with-modules="" ; cd
pdns ; make pdns_recursor, besides boost there are no dependencies when
compiled like this.
Relevant details from mtasker.hh

60 struct KeyTag {};
61 typedef multi_index_container<

63 indexed_by <
64 ordered_unique >,
65 ordered_non_unique >
66 >
67 > waiters_t;
68
69 waiters_t d_waiters;
From mtasker.cc:
http://wiki.powerdns.com/projects/trac/browser/trunk/pdns/pdns/mtasker.hh?re...
285 typedef typename waiters_t::template index<KeyTag>::type waiters_by_ttd_index_t;
286 waiters_by_ttd_index_t& ttdindex=d_waiters.get<KeyTag>();
Any ideas, especially on a workaround? It compiles fine on all gcc's I have
access to.
Thanks!
