sopc won't start, quartus ii 12.1, ubuntu 12.04

[Altera_Forum]

Hi 

 I have quartus ii 12.1 web edition and ubuntu 12.04. When I click the Tools->Sopc Builder I get the splash screen briefly but then nothing, it doesn't start. Same thing when I try it from the command line: ./sopc_builder/bin/sopc_builder. I get the splash screen but then nothing. There are no error messages. If there's a log file I could look through, please let me know. Any ideas?  Thanks...  Mike

I figured it out. First to see what is wrong with sopc_builder try this: 

 $ sopc_builder --debug_log=sopc-log.txt (you can use any log file name you choose, my guess is, they all offer some sort of command line debugging)  when I looked in the log, it said this: libXtst.so.6: cannot open shared object file: No such file or directory  so I did this: $ apt-get install ia32-libs  this installed the 32 version of libXtst.so.6, now it fires up  remember, this is all for ubuntu 12.04, not sure how this will work for other flavors  Happy designing...  Mike
