octave @3.8.2_5: build fails with +x11

[mndavidoff (Monte Davidoff)]

The octave +x11 variant fails to build.

$ sudo port -vs install octave +x11

The build succeeds if I omit "+x11" (sudo port -vs install octave).

Both FLTK and X11 define the default namespace type "Window"; this is why namespaces were invented! If either of them used a specific namespace (e.g., "fltk::Window"), we could do both +glgui and +x11 and have them not compete for resources. Ah well.

I can't imagine anyone wanting / needing both +x11 and +glgui, so I'm just making the variants conflict so that they cannot both be active. This issue should be fixed in r133035. Please do:

sudo port clean octave
sudo port selfupdate
sudo port install octave +x11

and see if that works. Please report back on this ticket either way.

[mndavidoff (Monte Davidoff)]

That works! Thanks!

Great; thanks for reporting back (really)! You're welcome.
