The Plcairo module is very young and still prone to changes in both
its build requirements and API, at least until the next PLplot
release. Thank you for your testing and reports in the mean time.
As of now, ocamlfind support is required for Cairo-OCaml in order for
the Plcairo module to be built. ocamlfind support for lablgtk2 is
only required to build the example examples/ocaml/xgtk_interface.ml
which uses the Plcairo module.
That explains why CMake does not find your lablgtk2 installation. I'm
not sure why the CMake configuration process is not finding your Cairo
OCaml install. It tests for Cairo OCaml by attempting to compile a
one line program:
module C = Cairo
using this compilation line:
${OCAMLFIND} c -package cairo -linkpkg \
test_cairo.ml -o test_cairo
If the compilation fails then the Plcairo module is disabled. A
similar test is made for Gtk, but in this case both the Gtk and
Cairo_lablgtk modules are checked:
module G = Gtk
module C = Cairo_lablgtk
compiled with:
${OCAMLFIND} c -package cairo.lablgtk2 -linkpkg test_gtk.ml -o test_gtk
If that OR the Cairo OCaml check fails then the xgtk_interface.ml
example is not built.
Could you test these and report back the results? Additionally, could
you send me the complete output from cmake as well as the complete
output from make when you build PLplot as attachments off-list?
Thank you for taking the time to test and report these issues.
