[Frama-c-discuss] Oxygen on Mac OS X Mountain Lion

Hello Boris,

thank you for your follow-up.
In the meantime , I have made considerably progress installing Frama-C Oxygen on
OS X in general and Mountain Lion (OS X 10.8.2) in particular.
Despite some challenges I found Oxygen much easier to install under OS X
than previous versions of Frama-C! 

Here is how I made it work:
I installed macports and and from there the following packages:

	sudo port install gtksourceview2
	sudo port install lablgtk2 +gtksourceview2
		(this one was tricky because macports mentions only a variant +gtksourceview (without the "2"))
	sudo ocaml-zarith ocaml-ocamlgraph
		(thanks for the hint to install zarith, Boris!)
	sudo port install graphviz
	sudo port install coq
	sudo port install djvulibre
		(I am not sure I really needed this package but I remembered that Pascal Cuoq
			had mention these fonts earlier)

Then I installed the alt-ergo binary under /opt/local/bin.
(I took the binary because configuring alt-ergo with prefix "/opt/local" would not find ocamlgraph
and I was too impatient to examine this more closely.)

Finally, I configured the Frama-C sources with prefix "/opt/local".
"make" and "make install" worked fine.

Under Mountain Lion the installed binaries "frama-c-gui" and "frama-c"
DO NOT WORK (segmentation fault). This is probably related to the bug of ocaml
under Mountain Lion mentioned here:
The solution is to use the executables "frama-c-gui.byte" and "frama-c.byte".
Under Lion (OS X 10.7) and Snow Leopard (OS X 10.6) the other binaries do work.

So far I have only tested Frama-C/WP.
