make: *** No rule to make target `make'.  Stop.

Not sure what the errors mean
The errors are to take quite literally:

You execute "make" with the arguments "foo" "." "make" and "$(EXE)".

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.

XmScrollVisible(3X)													       XmScrollVisible(3X)

NAME
XmScrollVisible - A ScrolledWindow function that makes an invisible descendant of a ScrolledWindow work area visible SYNOPSIS
#include <Xm/ScrolledW.h> void XmScrollVisible (scrollw_widget, widget, left_right_margin, top_bottom_margin) Widget scrollw_widget; Widget widget; Dimension left_right_margin; Dimension top_bottom_margin; DESCRIPTION
XmScrollVisible makes an obscured or partially obscured widget or gadget descendant of a ScrolledWindow work area visible. The function repositions the work area and sets the specified margins between the widget and the nearest viewport boundary. The widget's location rela- tive to the viewport determines whether one or both of the margins must be adjusted. This function requires that the XmNscrollingPolicy of the ScrolledWindow widget be set to XmAUTOMATIC. Specifies the ID of the ScrolledWindow widget whose work area window contains an obscured descendant. Specifies the ID of the widget to be made visible. Specifies the margin to establish between the left or right edge of the widget and the associated edge of the viewport. This margin is established only if the widget must be moved horizontally to make it visi- ble. Specifies the margin to establish between the top or bottom edge of the widget and the associated edge of the viewport. This margin is established only if the widget must be moved vertically to make it visible. For a complete definition of ScrolledWindow and its associated resources, see XmScrolledWindow(3X). SEE ALSO
