Hi,
a, hopefully, quick question.
First time trying to build the c++ qpidc-0.6
Working on Ubuntu 8.4, fresh install of boost etc.
Configure and Make proceed with out errors till:
Must remake target `libqpidcommon.la'.
when I get a lot of errors like
`.L2263' referenced in section `.rodata' of qpid/.libs/Url.o: defined in
discarded section `.gnu.linkonce.t._ZN4qpid7AddressC1ERKS0_' of
qpid/.libs/Url.o
for various values of linkonce.t.xxx and then ld exit status 1.
Has anyone any ideas where that may come from? Some incompatible tool or
library?
thanks for any clues.
Lionel.
The symbol it's complaining about is the copy constructor
qpid::Address::Address(qpid::Address const&). I suspect the fact that Address
has only inline functions is confusing your version of the compiler, I don't see
anything wrong in the code itself. Out-lining those function might help,
there's no good reason for them to be inline. Try the attached patch, if it
solves your problem I'll commit it.

Subject: [PATCH] Outline Address functions that don't need to be inline.
Fixes linking problems on some compiler versions.
