I am attempting to download and install Valgrind using the following instructions:I get through step 3 just fine, but when I type make I get the message make: *** No targets specified and no makefile found.  Stop.When I look through the new Valgrind directory I see files such as Makefile.am and Makefile.in, but as indicated no Makefile. The README file contains the same instructions as I posted in the picture, so I do not quite understand what I am missing. Thanks for any help!
Unable to use make to install Valgrind
command line;software installation
The step ./configure normally reads Makefile.in and writes Makefile. Something went wrong in running it. Run it again and read the output looking for errors. If that fails, read config.log where you might find a clue about what went wrong.
