Fatal error while installing Sqlite Browsers V 1.1

I am trying to install version 1.1 of the sqlite browser on Ubuntu 12.10 as every time I try to open the sqlite3 database the program throws an error. Apparently the fix is ​​to install version 1.1. Anyway, Im new for Linux, but I tried to follow the installation instructions. First I ran qmake (which returned nothing) and then I ran make. I ran into the following error. How to fix it? Thank.
