[Ipe-discuss] trouble installing CGAL ipelets

[Otfried Cheong]

In Ipe 7.1.7, the file extension for dynamic library has changed from
.so to .dylib on Mac OS X, to satisfy Apple's desire to be different.

The instructions https://3d.bk.tudelft.nl/hledoux/blog/ipe-cgal-ipelets/
seem to be for Ipe 7.1.6 or earlier, as they copy *.so files.

So probably all you need to do is to rename the .so files in
/Users/lenka/.ipe/ipelets to .dylib.

(And CGAL should update their build script.)

Cheers,
 Otfried
