I retried to type the export part (maybe i got something wrong). I read maybe i need to install libraries for 64 bit but because i'm still noob i didn't understand how to do it (and if this could be the problem). Still hundreds of warnings and 0 changed.
I downloaded the patch64 file and runned both patch_圆4 and sfk in both virtuoso tools and mmsim tools folders (i copied patch and sfk in those folders and i executed them). sfk command i get hundreds of warnings and 0 file changed so i suppose this could be the problem I followed all the instructions and overcome several problems but actually 'virtuoso' command is still not found. I'm still not able to solve some problem and i would appreciate any help (i'm still quite newbie on ubuntu). Thank you very much for the package and instructions and thank you everybody to post your problems (i got most of them, now solved).
