The software requirements for build and runtime are listed as follows:
Mandatory:
2011-09-17 - Third public release.
qxgedit-0.1.1.tar.gz
Previous and older releases, including the change log, are also available here. You may also check out from the latest bleeding edge development source tree, using Subversion.
You can browse all files available for download, including binary packages, at QXGEdit Files on SourceForge.net.
The installation procedure follows the standard for source distributions. In the extracted source directory, just do:
./configure[--prefix=prefix]
make
and optionally as root:
make install
This procedure will end installing the following couple of files:
/bin/qxgedit/share/applications/qxgedit.desktop/share/icons/hicolor/32x32/apps/qxgedit.pngJust launch prefix/bin/qxgedit and you're off (hopefully).
Note that the default installation path prefix is /usr/local.
QXGEdit holds its settings and configuration state per user,
in a file located as $HOME/.config/rncbc.org/QXGEdit.conf.
Normally, there's no need to edit this file, as it is recreated and
rewritten everytime qxgedit is run.
Plenty still, after all this is alpha software ;)
QXGEdit is open source free software. For bug reports, feature requests, discussion forums, mailling lists, or any other matter related to the development of this piece of software, please use the Sourceforge project page.
