164 # 1) Need to explicitly set LTCXXCOMPILE so that AM_CXXFLAGS is
165 # last. (That way, things like -O2 passed down from the toplevel can
166 # be overridden by --enable-debug.)
168 # 2) In general, libtool expects an argument such as `--tag=CXX' when
169 # using the C++ compiler, because that will enable the settings
170 # detected when C++ support was being configured. However, when no
171 # such flag is given in the command line, libtool attempts to figure
172 # it out by matching the compiler name in each configuration section
173 # against a prefix of the command line. The problem is that, if the
174 # compiler name and its initial flags stored in the libtool
175 # configuration file don't match those in the command line, libtool
176 # can't decide which configuration to use, and it gives up. The
177 # correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
178 # CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
179 # attempt to infer which configuration to use
180 LTCXXCOMPILE = $(LIBTOOL) --tag CXX --mode=compile $(CXX) $(INCLUDES) \

183 # 3) We'd have a problem when building the shared libstdc++ object if
184 # the rules automake generates would be used. We cannot allow g++ to
185 # be used since this would add -lstdc++ to the link line which of
186 # course is problematic at this point. So, we get the top-level
187 # directory to configure libstdc++-v3 to use gcc as the C++
188 # compilation driver.
