It has become painfully obvious to me that my experience in Windows hasn't prepared me for Linux. I recently downloaded qpopper3.0, I uncompressed it, configured it, ran make and nothing! I moved the file to /usr/local/bin as it suggested but I can't execute the file. I tried running it in xterm and just clicking on the executable file but it does nothing. What am I doing wrong? This same problem occurs with about 50% of the programs that I download.
