Is this a correct summary of what you wrote above? The xcairo device does not build properly for a cairographics environment that excludes X (for obvious reasons), but you found an alternative cairographics environment that does include X which works. Assuming that summary is correct, does -dev xcairo work at run time for you? If you feel our wiki at http://www.miscdebris.net/plplot_wiki/index.php?title=Mac_OSX_Status needs updating (say by adding the qualifier "cairographics must support X or else must specify -DPLD_xcairo=OFF") please do so. > [out of order] > the cairo driver of plplot implies it's using X11, which is not > necesseraly the case on the mac, more and more it's using quartz > natively. I agree with you (since Quartz is mentioned as a possible back-end for cairo) that programming an additional quartzcairo device would be desirable for the OS X case. It should also be straightforward; just follow the notes in drivers/README.drivers (just updated as of revision 10512) that list required changes for a new device. In general, the process is completely straightforward for everything other than the actual device code, but in this particular case that should be straightforward as well: edit drivers/cairo.c to duplicate what is done for xcairo for a new quartzcairo device except to change the calls to libpango/libcairo appropriately for the Quartz backend. Note, that we are all volunteers here who tend to work on our own PLplot priorities. So if nobody else here volunteers for the above straightforward job, I suggest you do it yourself (assuming you have some basic C knowledge), and send us a patch so that everybody can benefit from your work. I am sure everybody here would be willing to help you with any questions you might have about the process of adding a new device to PLplot, but the first place you should consult is (the newly updated) drivers/README.drivers.
