My specific situation is that I am trying to find out whether Apple bumped the system version of libcairo to 1.12.16 in Yosemite from an earlier version of libcairo in Mavericks.

I can somewhat easily find the version on my current system by inspecting the header files, but I can't seem to find that information online.

Does there exist a reference online for all the files included in different versions of OS X, or a way to find versions of system libraries (short of having access to a computer running a specific version of OS X)?

Failing that, I'd appreciate someone running Mavericks taking a peek in /opt/X11/include/cairo/cairo-version.h and telling me the version listed there.

  • Apple does not make such things public. You may consider visiting an Apple Store as they all their Macs are running Yosemite to gather the information you require.

  • Bummer, I thought that might be the case. My issue is that I am running Yosemite and trying to figure out which version of libcairo is in Mavericks.

    /opt/X11 is not part of anything installed by Apple

  • Mark's answer below is helpful in showing this - the Open Source pages he linked do not reference libcairo at all.

  • Mark's comment above may be more useful--it looks like libcairo may not be included in Yosemite, and something else installed it.

To answer the specific question, in newer releases, libcairo is part of cairo, which is part of XQuartz rather than the Apple-supplied X11 installation. You can find out the supplied version by checking the page for the release in question - for example, here for 2.7.7.

As has been answered by Mark, the Apple Open Source site provides listings of all of the open source software included in each release.


Look at the Apple pages listing the open source products in each release. Unfortunately the Yosemite page has not been added yet.
