(That way, things like -O2 passed down from the toplevel can # be overridden by --enable-debug.) # 2) In general, libtool expects an argument such as `--tag=CXX' when # using the C++ compiler, because that will enable the settings # detected when C++ support was being configured. However, when no # such flag is given in the command line, libtool attempts to figure # it out by matching the compiler name in each configuration section # against a prefix of the command line. The problem is that, if the # compiler name and its initial flags stored in the libtool # configuration file don't match those in the command line, libtool # can't decide which configuration to use, and it gives up. The # correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe # CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to # attempt to infer which configuration to use LTCXXCOMPILE = $(LIBTOOL) --tag CXX --mode=compile $(CXX) $(INCLUDES) \ $(AM_CPPFLAGS) $(CPPFLAGS) $(CXXFLAGS) $(AM_CXXFLAGS) # 3) We'd have a problem when building the shared libstdc++ object if # the rules automake generates would be used. We cannot allow g++ to # be used since this would add -lstdc++ to the link line which of # course is problematic at this point. So, we get the top-level # directory to configure libstdc++-v3 to use gcc as the C++ # compilation driver.
