    make file

    I am trying to make a makefile(makeSupersonic) for the following compilation:

    > g++ -o supersonic_ob supersonic_ob.C flow_field.C function_declarations.C Boundary.C Time_Step.C -lm

    Code:
    GCOMPILE = g++-4.0
    FOPTIONS = 
    CODE     = supersonic_ob1
    
    OBJECTS = $(CODE).o  flow_field.o  Boundary.o   Time_step.o   function_declarations.o 
    $(CODE): $(OBJECTS)
    	$(GCOMPILE) -o $(CODE) $(FOPTIONS) $(OBJECTS)
    
    $*.o:   $*.C 
    	$(COMPILE)
    It gives the following error messages when I type
    >./makeSupersonic

    ./makeSupersonic: line 1: GCOMPILE: command not found
    ./makeSupersonic: line 2: FOPTIONS: command not found
    ./makeSupersonic: line 3: CODE: command not found
    etc....

    It sort of looks like you're trying to execute the makefile itself... (should it have executable permission + it lacks a shebang? Not a *nix expert here...)
    Just run make. ie:
    Code:
    make -f makeSupersonic
    Also, "GCOMPILE" seems... outlandish. I believe most people use CPP there, and it might already (depending on your make and system) be already set to g++.
    You should also have tabs before the commands (but not the rules) but this may have been lost to the board's formating. IIRC, it's:
    Code:
    %.o : %.c
    (without $s, and using %s.) (And COMPILE is undefined...)
    long time; /* know C? */
    Unprecedented performance: Nothing ever ran this slow before.
    Any sufficiently advanced bug is indistinguishable from a feature.

    Attach the file. It is likely an indentation issue.
