Porting to visual studio..

[Philippe Torrelli]

Hi Cesc and Paul,

Sorry if I didn't answer each  mail separately, I subscribed to the list in
digest mode. 
I changed it now.

Basically what I need is a soft phone able to TLS/SRTP that I can embed in
an ActiveX . 

The functions I need is basic audio call ( no video / but decent audio codec
) receive sip calls.

There will be no GUI in the ActiveX but call methods / call events
(IConnectionPoint ) so that the GUI can be in the browser ( or activeX host
), and the configuration is given in the properties passed to the ActiveX.

As minisip seems to be a very good starting point, I'm trying to do a
proof-of-concept..

My understanding of the architecture of Minisip is that it can be achieved
with a reimplementation of the TextUI / Minisip classes - didn't sort it out
completely yet, I need to experiment with the code to have a better
understanding... 

I don't know if this alternative 'GUI' will be  interesting for other
people... 
For the rest, as the LGPL states, every single change in the libs will of
course be published, as I will probably need to implement a ConfBackEnd
class and maybe change / adapt the plugin interface..

To do that I have a vs2005 build environment that I set up this way:
* I built a bunch of vcproj that were translations of Makefiles / config.h /
compilation_config.h generated from a cygwin build of minisip.

In a few files I found no better way but to change code that didn't compile
( for example extern "C" functions returning C++ templates instances in
plugin api ) ... 

Also tweaked  a tldl.[ch] file a lot so that it is  able to compile...  (
definitely needs more work ).

There are also many places where extra #include(s) needed to be added
because of references to incomplete classes that VS doesn't like when it
expands MRef templates , and also ( not yet fixed ) many warnings about
calls to deprecated functions ( of the sprintf/strdup... family ) .

My modifications are quite raw and I need to track it all back and
rationalize each of it ( in a way that doesn't break other build as Cesc
pointed out ) before it can be submitted. 

Probably a matter of two weeks as I don't work full time on this.

After that I will try to re-apply it to a more recent build and will post
these.

Before I do that I want to have a minisip-textui built with vs2005 that
works as well as the one cross compiled out of my red hat box, so now I'm in
the process of testing the exe .

( My current minisip_textui registers, accepts and send calls but the
mdsound plugin doesn't seem to work correctly as neither me nor my parties
hear anything - RTCP UDP packets are issued anyway ... 
There seem to be a weird behavior when registering  with digest
authentication to a SER proxy but I checked with the mingw build and it's
the same.. No tls, or gsm codec yet...)


Thank you for your interest and remarks
