I am attempting to build QGIS 1.4.0 from source for a windows plaform
(XP) using the MSYS instructions in the coding and compilation guide. I
have downloaded the preprepared msys.zip to make things simpler.
1. The guide appears to imply MinGW is in the msys.zip file. This is not
true. (Dropped out at some point?)
My solution: Point CMAKE gui to my MinGW that comes with Qt.
2. QTVARS.BAT appears to have disappeared in the latest Qt builds. Has
QTENV.BAT possibly replaced it?
3. I appear to successfully get through all phases of CMAKE and have it
generate the makefiles.
During the make, I get the following errors..
C:\dev\cpp\qgis\build>mingw32-make

mingw32-make: *** [all] Error 2
Further digging shows the define DBT_DEVTYP_DEVICEINTERFACE is in the
<dbt.h> included in MinGW libraries, but is not getting defined because
neither _WIN32_WINDOWS or _WIN32_WINNT is defined at all. A quick and
dirty edit, just to see if getting past this one error would get me
moving ahead shows that there are larger issues in dbt.h that need to be
dealt with.
Ideas?
