You can modify Makefile, or you could run ./configure and let it make
the modifications. Did you run ./configure before you ran make?
Any text editor can be used to modify Makefile. I use either MC's edit
mode or Pico.
Standardized structure? If you are trying to modify Makefile to include
libraries in non-standard locations (which uses the -L switch as apposed
to the -l switch for libraries in the standard paths) and you haven't
read/don't know what these switches mean and what the standard paths are
then you have the cart before the horse. The -i switch is for libraries
in /usr/lib and the -L switch is for libraries in other locations. I
haven't said anything about the 'shorthand' used to represent the
libraries: say you have a program called LeastSquares and you are using
functions found in a static math library, libm.a, which is in /usr/lib.
You would compile LeastSquares by issuing:
cc -o LeastSquares -lm
Why didn't I include the whole name of the library? Because libraries
begin with 'lib' and the shorthand is not to include 'lib' - the switch
knows to prefix m with 'lib' to get libm.
How does -l know to append an 'a' and not 'sa' (for shared libraries)?
Well, see how the topic is growing? And the questions you're asking
indicates you haven't even read the fundamentals.
It time you took a breather from the mail-list server, got a good book
on compiling and did some practice programming and compiling. Let me
recommend "Beginning Linux Programming" and "Practical C++ Programming"
and "Linux Application Development". They are at Amazon.com.
No need to appoligize, we understand. ;-)

Linux, because it's STABLE, the source code is included, the price is
right.
