Suppress upstream ARPACK compiler warnings (!188) · Merge requests · Core Modules / dune-istl

Steffen Müthing requested to merge bugfix/suppress-arpack-compiler-warnings into master Feb 14, 2018

This patch gets rid of the compiler warnings generated by the antiquated ARPACK sources by turning the ARPACK include directory into a system include directories. Compilers don't generate warnings for code in system include directories, so this is a blanket solution for all kinds of problems in this source (that we treat as upstream and thus can't fix anyway).
