How to add CFLAGS and CXXFLAGS in makefile?
To do it on the configure line: ./configure CFLAGS=’-g -O2 -w’ CXXFLAGS=’-g -O2 -w’. To do it on the make line: make CFLAGS=’-g -O2 -w’ CXXFLAGS=’-g -O2 -w’. However, that doesn’t really remove consider all warnings as errors; that removes all warnings. So specifying both -Wall and -w doesn’t make sense. If you want to keep the warnings but not
What is the correct syntax to add CFLAGS and ldflags to?
