[QGIS-Developer] Debug C++ QGIS plugin with VS

Hi List,

We have a problem with a QGIS plugin developed in C ++ and the developer
left us with a debug environment that did not work..

We managed to recreate an environment that allows to build the dll: it
works with version 2.18 of GIS!
When we have a bug, we do not have what it takes to develop properly.

We are therefore looking to associate QGIS with visual studio and be able
to take step by step by associating with the process.
For the moment when we build with the DLL / lib of dev it build but when
launching the plugin, QGIS crash with a message
Debug Assertion Failed! Expression: _pFirstBlock == pHead
If we try to focus on the process, in release, we can not do anything ...

We would need a tutorial that presents the best practices and prerequisites
to build this enviroment environment (on windows 😶 )
QGIS 2.18.5
VS 2013
QT 4.8.6

Do you have that?

Thank you all
(sorry for googletrad)
