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.

AIMK(1PVM) PVM Version 3.4 AIMK(1PVM)
NAME
aimk - Portable make wrapper script
SYNOPSIS
aimk [ -here ] [ make arguments ]
DESCRIPTION
aimk is a wrapper program for make, used to portably select options to build PVM and PVM applications on various machines. Each port of
PVM is assigned an architecture name. The name is used both during compilation (to conditionally switch in code) and at runtime (to select
an executable or host).
aimk uses the value of environment variable $PVM_ARCH if it is set, otherwise it calls $PVM_ROOT/pvmgetarch to determine the architecture
name. pvmgetarch is a script that sniffs at various parts of the system to determine the correct architecture name. It is updated as new
PVM ports are defined, and can be augmented locally.
aimk determines the machine architecture and execs make, passing it the architecture and a configuration file along with arguments supplied
to aimk. It runs make in a subdirectory to prevent executables from becoming intermixed and to permit overlapping compiles. A different
makefile can be placed in each subdirectory or a single makefile, Makefile.aimk, can be shared between architectures. Per-architecture
definitions from the $PVM_ROOT/conf directory are appended to the common makefile. aimk calls make is called in one of three ways, depend-
ing on what makefiles are present:
i. If $PVM_ARCH/Makefile or $PVM_ARCH/makefile exists, change directory to $PVM_ARCH and exec make there:
(cd $PVM_ARCH ; make PVM_ARCH=$PVM_ARCH < aimk args >)
ii. Else if Makefile.aimk exists, create $PVM_ARCH directory if it doesn't exist, then:
(cd $PVM_ARCH ;
make -f $PVM_ROOT/conf/$PVM_ARCH.def
-f ../Makefile.aimk PVM_ARCH=$PVM_ARCH < aimk args >)
iii. Else just exec make in current directory:
make PVM_ARCH=$PVM_ARCH < aimk args >
If aimk succeeds in calling make, the exit status is that of make, otherwise it is 1.
FLAGS
-here Forces aimk to run make in the current directory, e.g. converts case i. to case iii.
EXAMPLES
The following Makefile.aimk file builds and installs hello, creating the PVM binary directory if it doesn't exist. It can be run concur-
rently on machines of different types, sharing the same source directory.
LDIR = -L$(PVM_ROOT)/lib/$(PVM_ARCH)
PVMLIB = -lpvm3
SDIR = ..
BDIR = $(HOME)/pvm3/bin
XDIR = $(BDIR)/$(PVM_ARCH)
CFLAGS = -g -I$(PVM_ROOT)/include
LIBS = $(LDIR) $(PVMLIB) $(ARCHLIB)
$(XDIR):
- mkdir $(BDIR) $(XDIR)
hello: $(SDIR)/hello.c $(XDIR)
$(CC) $(CFLAGS) -o $@ $(SDIR)/$@.c $(LIBS)
mv $@ $(XDIR)
ENVIRONMENT
$PVM_ROOT Root path of PVM installation.
$PVM_ARCH PVM architecture name for machine.
FILES
$PVM_ROOT/lib/aimk The aimk program
$PVM_ROOT/conf/$PVM_ARCH.def Arch config file
