CGAL users discussion list

[Lindley M French <>]

All right, I've figured out that using cgal_create_makefile causes most of 
the errors to go away.

But I'm not sure how to modify the generated makefile to include my own 
headers. Seeing as the line:

-I../../include

doesn't actually point to anything interesting, I figured I'd modify it to 
point to the [i]current[/i] directory. (Which really should be in the search 
path already, but apparently isn't because a header file there isn't being 
found.)

But when I make that line:

-I./

The all the CGAL errors come back again.
