makefile

[Lars Kristiansson <md8lars at mdstud dot chalmers dot se>]

Hi!

(Sorry! A new copy with this mail WITH the Makefile)

I have some problems with the attached Makefile:

When I compile and link all as in the rule uppg4: everything works fine,
but I do want to split up compiling and linking, so I can divide my huge
main file uppg4.c into different objectives s.a. uppg4.o, myrnd.0 and so
on, to link them together later. Also I need to check for errors during my
development.

So I divided everything up, using rules uppg41.o: and uppg41:

Now I encounter the errors:

--------------------------------------------------------------------

--------------------------------------------------------------------

and I don't know what's wrong? Everything is included and linked just as
it should be supposed to, but the libraryfunctions in glut doesn't seem to
be found at all!

There must be a way to divide large items up...
