[Marble-devel] issues with using the marble widget on windows / mingw / Qt 4.7.3

[Ákos Maróy]

Hi,

I'm trying to compile the C++ sample app for marbles, as found here: 
http://techbase.kde.org/Projects/Marble/MarbleCPlusPlus , on a Windows 7 
(64 bit) box.

I've installed Qt 4.7.3 for Windows, and created a simple project as 
described in the tutorial. Everything compiles fine (although only in 
release mode). but when I start the sample app, I get a window that is 
totally dark. Maybe it is not downloading the map data?


On a different side note, I tried to compile marble in static mode by 
adding -DSTATIC_BUILD=1 to the cmake command. but this compilation 
process fails:

and indeed, there is no libqjpeg or qjpeg among the Qt libraries. Maybe 
Qt does not come with static libraries by default?
