Yes it does. However, if you look at the
actual -I options you reported in your original post, the only one that
involved plplot/include/plplot is
-I"C:\Program
Files\plplot\share\plplot5.9.5\examples\c\Files\plplot\include\plplot"
which obviously has a wrong (much too long) prefix consisting of
the source tree directory with everything after the blank in
"Program Files/plplot/include/plplot" appended.
Thus, I suspect that blank is the source of the problem here. Could you try
again with an install prefix that doesn't have a blank in it?
Also, I don't think it has anything to do with the current problem, but it
is probably better/cleaner to use a separate build tree for building and
testing the installed examples rather than mixing the build and test in with
the installed examples.
Happy New Year's Eve! to everybody here.
