Please describe the problem:
This warning should not be issued in this context. I can build code with no warnings, and am "using Rc::Exec::HelperThread;" right above the implementation.

C:/users/npcostes/TGP-branch/B52TGP/TgpLib/Rc/Tgp/HelperThreads/CaptureThread/Requests/SetCaptureThreadChannel.cpp:26: Warning: no matching class member found for
SetCaptureThreadChannel::SetCaptureThreadChannel(Rc::Tgp::HelperThreads::CaptureThreadChannel channel, HelperThread *helperThread)
Possible candidates:
Rc::Tgp::HelperThreads::SetCaptureThreadChannel::SetCaptureThreadChannel(const Rc::Tgp::HelperThreads::CaptureThreadChannel channel=Rc::Tgp::HelperThreads::CaptureThreadChannel::e_flir, Rc::Exec::HelperThread *helperThread=0)
Rc::Tgp::HelperThreads::SetCaptureThreadChannel::SetCaptureThreadChannel(const SetCaptureThreadChannel &request)

SetCaptureThreadChannel (const Rc::Tgp::HelperThreads::CaptureThreadChannel channel = Rc::Tgp::HelperThreads::CaptureThreadChannel::e_flir,
Rc::Exec::HelperThread* helperThread = 0);

using Rc::Tgp::HelperThreads::SetCaptureThreadChannel;

using Rc::Tgp::HelperThreads::CaptureThreadChannel;
using Rc::Exec::HelperThread;

SetCaptureThreadChannel::SetCaptureThreadChannel(const CaptureThreadChannel channel,
HelperThread* helperThread)
: HelperThreadRequest(HelperThreadRequest::Type::e_setCaptureThreadChannel, helperThread),
m_channel (channel)
setHelperThreadName ("CaptureThread");

Steps to reproduce:

  1. Run doxygen on the above code.

Actual results:

Expected results:

Does this happen every time?

Other information:
If I change the implementation to be

const CaptureThreadChannel channel, Rc::Exec::HelperThread* helperThread)

Then doxygen emits no warning. Note that since I am "using Rc::Exec::HelperThread;" I think I should not have to fully qualify it in the implementation (esp. since it compiles w/no warnings).

Also, adding a "using namespace Rc::Exec;" instead of "using Rc::Exec::HelperThread;" doesn't help. Only fully qualifying the parameter type as Rc::Exec::HelperThread* makes the Doxygen warning go away.

PS: Thank you so much for writing and maintaining Doxygen, it is a wonderful tool.

Here's a small and self contained testcase:

template struct B {
struct I { I(); };

template struct D : B {};

B::I::I () {}

For this one I get the following:

/precondition_block.h:8: Warning: no matching class member found for
template < T >
B< T >::I::I()

Wolfgang: thanks for the test case.
The problem should be fixed in the next release.

This bug was previously marked ASSIGNED, which means it should be fixed in
doxygen version 1.6.0. Please verify if this is indeed the case and reopen the
bug if you think it is not fixed (include any additional information that you
think can be relevant).
