You can download the latest release as source code on SourceForge.There will be a win32 binary, too.

For the bleeding edge of development you have to use the SVN repository. For initial checkout:

	svn co https://qlandkartegt.svn.sourceforge.net/svnroot/qlandkartegt/QLandkarteGT/trunk QLandkarteGT

To build (out of source build, start one level above source root directory)¹:

	mkdir build_QLandkarteGT 

	cd  build_QLandkarteGT 

	ccmake ../QLandkarteGT 

CCmake can be controlled by keys. Watch out for key hints at the bottom. Especially the"c" and"g" key. You might want to check for the value of CMAKE_INSTALL_PREFIX. The default is usually "/usr/local". However most distributions expect everything to be prefixed with "/usr".  A bad prefix might result in missing localization. 

Next you do:

	make

The binary will be placed in ./bin. To catch up latest changes (in the source root directory):

	svn up

To send a patch (in the source root directory):

	svn diff > patchname.diff

As user you might want to do a

        sudo make install

to copy all stuff into your system.
