173 # 1) In general, libtool expects an argument such as `--tag=CXX' when
174 # using the C++ compiler, because that will enable the settings
175 # detected when C++ support was being configured. However, when no
176 # such flag is given in the command line, libtool attempts to figure
177 # it out by matching the compiler name in each configuration section
178 # against a prefix of the command line. The problem is that, if the
179 # compiler name and its initial flags stored in the libtool
180 # configuration file don't match those in the command line, libtool
181 # can't decide which configuration to use, and it gives up. The
182 # correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
183 # CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
184 # attempt to infer which configuration to use.
186 # The second tag argument, `--tag disable-shared` means that libtool
187 # only compiles each source once, for static objects. In actuality,
188 # glibcxx_lt_pic_flag and glibcxx_compiler_shared_flag are added to
189 # the libtool command that is used create the object, which is
190 # suitable for shared libraries. The `--tag disable-shared` must be
191 # placed after --tag CXX lest things CXX undo the affect of
194 # 2) Need to explicitly set LTCXXCOMPILE so that EXTRA_CXX_FLAGS is
195 # last. (That way, things like -O2 passed down from the toplevel can
196 # be overridden by --enable-debug.)
