[vtk-developers] libc++ problem on OSX

[Biddiscombe, John A.]

Thanks to all of you,

In my cache there was a VTK_REQUIRED_OBJCXX_FLAGS libstdc++ setting. I put that right and now I’m past that problem.

Yours

JB

I completely forgot about VTK_REQUIRED_OBJCXX_FLAGS.

CMake doesn't (bug 4756) but VTK does: "VTK_REQUIRED_OBJCXX_FLAGS"

<http://public.kitware.com/Bug/view.php?id=4756>

VTK does work with libc++ and I have several dashboards that use it.  The link error does suggest however that some files are using libstdc++ and some others using libc++.  Maybe try adding -stdlib=libc++ to VTK_REQUIRED_OBJCXX_FLAGS also, though I don't believe I've had to do that...

Cheers,
