[Qgis-developer] Build QGIS with QtCreator, LNK2019 error

[Zeben M. C.]

I'm trying to build QGIS with QtCreator. I am following the instructions
found in:
 https://github.com/qgis/QGIS/blob/master/CODING (4. Getting up and running
with QtCreator and QGIS).

When I build the project (using Jom) always fails with this error:

--------------------

-----------------

Also, i have several previous warning in the console as:
 - some macro redefinition and
 - or: -1: Warning: LNK4098: defaultlib 'MSVCRT' Conflicts with use of
other libs; wear / NODEFAULTLIB: library

Also using NMAKE (instead JOM), it fails. The error take place much later
in the build but fails.

I am able to build QGIS using Visual Studio 2008 but with the aim of more
easily debug, I trying to use QtCreator..

Any idea?

My goal is to build a slightly modified version of Qgis able, among other
things, to create polygons the same way to create rings.

Thanks in advance.
