[GRASS-user] g.gui not launching in grass70 after install

[Michel Wortmann]

Hi list,
After compiling grass70 from source on our linux server, it fails to 
launch the wxpython gui with the following error:

Launching <wxpython> GUI in the background, please wait...

Other g.gui.* apps start ok. The only errors during make were that it 
couldnt find the LOCATION of the demolocation. I saw that 
grass-7.0.svn/etc/gui/wxpython/xml/menudata.xml is empty, could that be 
a possible cause?

Any hint is much appreciated.
