I want to add --enable-debug switch to my configure script, which replaces
default "-g O3" compiler options with "-g3 -O0". My attempt is obviously
incorrect:
AC_ARG_ENABLE( debug,
[ --enable-debug, Enable debug build],
[ CXXFLAGS="${CXXFLAGS} -g3 -O0"] )
This gives compiler command line: "-g O3 g3 -O0" instead of desired "-g3
-O0"
Also, automake manual doesn't recommend to touch CXXFLAGS variable, leaving
it completely to user. What is correct way to do this?
