Revert to the canonical way of customizing CXXFLAGS A default list of compiler flags is set via AM_CXXFLAGS Automake variable. However this gets overridden by per-target CXXFLAGS variables (e.g. foo_CXXFLAGS in case the foo target). Because of this you should append $(AM_CXXFLAGS) to the end of the per-target CXXFLAGS variables (e.g. foo_CXXFLAGS = ... $(AM_CXXFLAGS)). After this default list of flags the contents of the CXXFLAGS user variable is passed to the compiler. This variable has a default value determined by configure (in case of g++ it is '-g -O2'). You can override this by specifying CXXFLAGS when invoking make (e.g. make CXXFLAGS='-O3').
