compile error in exemple 6

(note I have renamed exampl6.cpp inmain.cpp)

Any updates on this issue?

Got these errors:
[build] /usr/include/c++/7/ext/new_allocator.h:136:4: error: invalid new-expression of abstract class type ‘myTracerFactory’ [build] { ::new((void *)__p) _Up(std::forward<_Args>(__args)...); } [build] ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In the method:

vmime::shared_ptr <vmime::net::tracer> create(
		vmime::shared_ptr <vmime::net::service>& serv,
		const int connectionId
	) {
		return vmime::make_shared <myTracer>(stream, serv->getProtocolName(), connectionId);
	} 

You need to change:

vmime::shared_ptr <vmime::net::service>& serv,

to:

vmime::shared_ptr <vmime::net::service> serv,

As you could notice checking the abstract class.

I have changed the code as you suggested but this caused even more errors now.
Is there a working example of this VMIME send email with authentication?

[vincent-richard]

The correct prototype for the method is:

shared_ptr <tracer> create(const shared_ptr <vmime::net::service>& serv, const int connectionId);

Be sure to use the latest VMime code from the Git repository. Method takes a const shared_ptr<>& argument, not a shared_ptr<>& nor a shared_ptr<>. This has changed on August 2018.
