#284: Improve compiler flag discovery in configure.ac ---------------------------+------------------------ Reporter: levill_r | Owner: Olena Team Type: enhancement | Status: new Priority: minor | Milestone: Olena 2.2 Component: Olena | Version: 2.0 Keywords: configuration | ---------------------------+------------------------ We should test whether the selected C++ compiler supports a given flag (e.g. `-O3`) rather than encode a set of flags for a specific compiler (e.g. in `CXXFLAGS`) and try to guess which compiler are we using (`g++`, `clang++`, `icpc`, etc.). -- Ticket URL: <https://trac.lrde.epita.fr/olena/ticket/284> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient image processing platform
