[MinnowBoard] Ask informations MinnowBoard max

[idealsim]

Thank's for your answer. About Qt, i already use on ubuntu 14.04 and digia  
give binary package for it (like installer.exe for windows) :  
http://www.qt.io/download-open-source/#. In fact, i just want to know if i  
can install on minnowboard max a software like a standard pc that have x86  
processor like corei3 (word,excel ...on windows sure ...)

regards
