The first error is from the shell, because "$(EXE)" means run command "EXE" in a subshell and put its output here. The shell thinks that the rest of the command depends on what EXE might output and therefor execute it first - as there is no "EXE, this fails.

Next, "make" is executed and takes the argument: "foo". For "foo" exists a target to make and "make" does try to make it but notices that it has already done so and in the meantime "foo" hasn't changed - so it tells you that "foo" is already up to date. Next make tries to "make .". As "." is the current directory and there is no rule in your makefile describing how to make "." "make" tells you so. Finally it tries to make "make", which would be (like ".") a perfectly valid target to make - IF it would exist in your makefile. As it doesn't, "make" tells you the same as with ".": it can't make it, because you haven't told it how.

But instead of writing a long-winded make-exegesis, i could probably tell you what you need to know, so: what exactly do you want to achieve? Have you ever used a makefile and know its purposes? Its syntax?

I hope this helps.

I am trying to Compile a C program. Run a C program. Run a Python program. Compile and run a java program. Check for a README, display it. Compare 2 files. Clean up intermediary files.

I am only on the first part right now, because run does not seem to work.

PAPS(1) 						      General Commands Manual							   PAPS(1)

NAME

       paps - UTF-8 to PostScript converter using Pango

SYNOPSIS

       paps [options] files...

DESCRIPTION

       paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
       through the pango ft2 backend.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.

       --landscape
	      Landscape output. Default is portrait.

       --columns=cl
	      Number of columns output. Default is 1.
	      Please notice this option isn't related to the terminal length as in a "80 culums terminal".

       --font=desc
	      Set the font description. Default is Monospace 12.

       --rtl  Do right to left (RTL) layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter and A4. Default is A4.

       Postscript points
	      Each postscript point equals to 1/72 of an inch. 36 points are 1/2 of an inch.

       --bottom-margin=bm
	      Set bottom margin. Default is 36 postscript points.

       --top-margin=tm
	      Set top margin. Default is 36 postscript points.

       --left-margin=lm
	      Set left margin. Default is 36 postscript points.

       --right-margin=rm
	      Set right margin. Default is 36 postscript points.

       --gutter-width=gw
	      Set gutter width. Default is 40 postscript points.

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --lpi  Set the lines per inch. This determines the line spacing.

       --cpi  Set the characters per inch. This is an alternative method of specifying the font size.

       --stretch-chars
	      Indicates  that  characters  should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
	      behaviour.
