Gordon Sim resolved QPID-5134.
------------------------------
Resolution: Won't Fix
The issue as reported is still there, but since the amqp 1.0 plugin no longer
tries to use those symbols, it isn't really a problem.
> Windows compile error - framing::Buffer::getUInt() not exported from dll
> ------------------------------------------------------------------------
>
> Key: QPID-5134
> URL: https://issues.apache.org/jira/browse/QPID-5134
> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker
> Affects Versions: 0.24
> Environment: Windows + proton
> Reporter: Chuck Rolke
>
> In framing::Buffer.h
> {code}
> template <int n>
> QPID_COMMON_EXTERN uint64_t getUInt();
> {code}
> In framing::Buffer.cpp
> {code}
> template <>
> uint64_t Buffer::getUInt<1>() {
> return getOctet();
> }
> template <>
> uint64_t Buffer::getUInt<2>() {
> return getShort();
> }
> ...
> {code}
> The code fails to link:
> {noformat}
> error LNK2019: unresolved external symbol
> "unsigned __int64 qpid::framing::Buffer::getUInt<4>(void)"
> referenced in function
> "unsigned int qpid::broker::amqp::OutgoingFromQueue::Record::
> getIndex(struct pn_delivery_tag_t)
> {noformat}
> In previous issues (QPID-2926) windows code has manually generated instances
> of the template functions so that the DLL could export them. This time that
> trick doesn't work.
> Is this code a violation of "The implementation of template functions must be
> available in accessible header files to enable the compiler to generate the
> code for the concrete type." ?
> For completeness there is also a failure sister Buffer::putUInt<n>()
> functions. Probably the same fix would be good for both errors.
> I can think of some c-style solutions for this problem that would work
> straight away...
