Hi everyone, I am working on a project that I joined and I noticed that the flags are all a mess. When a flag called --enabled-debug was set it it sets AM_CXXFLAGS="$AM_CXXFLAGS -g -Wall -O0" AM_LDFLAGS="$AM_LDFLAGS -g" but when I compile all of my stuff, the CXXFLAGS variable is set to -g -O2 which completely negates the ability to debug. Likewise, I want to set LDFLAGS to actually link the compiled libraries first as oppose to anything that I have installed. I don't think this is a problem as LDFLAGS apparently doesn't have a default for autoconf, or at least not one that overrides. I am actually surprised that autoconf decided that the default CXXFLAG set was not empty. I am sure there are reasons for that, but to me it causes more harm than good. I set AM_CXXFLAGS with the expectation that if I don't explicitly set CXXFLAGS, that I get to use whatever I set for AM_CXXFLAGS but that is not the case. Even in build mode AM_CXXFLAGS="$AM_CXXFLAGS -O3" will be overridden to be -g -O2 by CXXFLAGS. Basically, what I want is the expected default behavior. I want to set CXXFLAGS to nothing by default unless it has been specified by the user. It is very strange that this is not how it works so I suppose I am also curious as to why this is the case.
