The last few times I used the autotools programs, I had to redirect input from /dev/null, or they would never finish.
I mean ./configure
long ago would run by itself. The same for the others. No longer. At least not for me.
So, if it's not just me, I'll probably post a bug in the appropriate place, but until then I thought I'd find out if other programmers using Ubuntu or Xubuntu are seeing this.
