[GRASS-user] install module > Compilation failed

[frank]

Dear all,

I try to install wms modules but without success !
the command g.extension extension=wx.wms url= return :

make: ***  Aucune règle pour fabriquer la cible « /tmp/gr
ass7-frank-26646/tmpi1oKCi/wx.wms/etc/gui/wxpython/gui_modul
es/wms/serverList.txt », nécessaire pour « default ».
Arrêt.
ERROR: Compilation failed, sorry. Please check above error messages.

I've tried on an other computer but it's the same. I don't know how to 
find serverList.txt and if it's the reason of the dysfunction.

I'm on debian stretch and GRASS 7.2.0

Thank you for your help

Frank
