libsystem_symptoms.dylib missing in Xcode 8

Question

I just updated to Xcode 8, and I can no longer build xml2-based applications. If I build a simple file and try to build it as follows:

c++ myapp.cc `xml2-config         


        

Answer 1

The final update from geoHeil on https://github.com/igraph/rigraph/issues/173 helped me resolve this issue on OSX.

It was as simple as these two steps:

Terminal> brew uninstall suite-sparse --ignore-dependencies
R> install.packages("igraph")

ignore-dependencies was necessary because Octave had a dependency on suite-sparse.
