[Openstreetmap] Questions about osmeditor

osmeditor does not use gd. The gd application is a separate application to
allow you to generate PNG tiles containing NASA SRTM contours. It is not
used by osmeditor (but the contour generation code is).

One of the big problems ATM is that I have to maintain separate Qt3 and Qt4
versions. This is because most Linux desktop environments use Qt3 at the
moment, while the Windows free edition is Qt4. The sooner KDE4 comes out
the better, then everyone can move to Qt4....

It doesn't use qmake yet, just type "make osmeditor2".
However, it probably should do. One for the todo list...

Yes, probably they should be in separate directories too.

>3 - (I knew there were more than 2 questions) - is there a special reason
for

that)

It's an artefact of projecting the globe of the earth onto a flat surface.
Again on the (longer term) todo list...
