Hi
I'm trying to build QGIS on Windows 7 (x64) using the the steps provided in [1]
with small adjustments from [2]. My objective is to be able to build a QGIS
instance so that I can debug and understand the calls made to QGIS from my
python plugins. In other words, I am not trying to build my own installer with
a custom QGIS build - just debugging the standard QGIS application.
I have installed on my plain and clean Windows 7 x64 machine:
VS2010 C++ Express
Microsoft SDK (from ISO file)
Cygwin64: Bison, Flex
Osgeo4W64: A lot of packages
CMAKE 3.0.2 x86
I am not sure if I need to build everything and if I need to build either
"debug" or "RelWithDebInfo" in my case when I just need to debug calls made
from Python to the QGIS application?
Currently I'm trying to just build "qgis" (1 of 334 projects listed in my
Solution Explorer) using the "debug" setup. Do note that my knowledge in C++ is
very limited.
I'm currently stuck in Visual Studio 2010 C++ Express with a lot of linking
errors apparently related to spatialite and I would really like a hint or two
on how to get by this obstacle:
