I need to install Qt library 4.7.4 on Ubuntu.
What I did:
1. Downloaded an archive of the library (for Linux) from official site.
2. Unpacked it to /usr/local
3. Started ./configure (it took a several minutes)
4. Than entered make command and got an obstacle (on the picture)
I have been spending a lot of time to solve the problem, but I no way could do it.
Question: What did I do incorrectly and what I must do to correct a mistake.
P.S. Sorry for my English
