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