206 # 1) In general, libtool expects an argument such as `--tag=CXX' when
207 # using the C++ compiler, because that will enable the settings
208 # detected when C++ support was being configured. However, when no
209 # such flag is given in the command line, libtool attempts to figure
210 # it out by matching the compiler name in each configuration section
211 # against a prefix of the command line. The problem is that, if the
212 # compiler name and its initial flags stored in the libtool
213 # configuration file don't match those in the command line, libtool
214 # can't decide which configuration to use, and it gives up. The
215 # correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
216 # CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
217 # attempt to infer which configuration to use.
219 # The second tag argument, `--tag disable-shared` means that libtool
220 # only compiles each source once, for static objects. In actuality,
221 # glibcxx_lt_pic_flag and glibcxx_compiler_shared_flag are added to
222 # the libtool command that is used create the object, which is
223 # suitable for shared libraries. The `--tag disable-shared` must be
224 # placed after --tag CXX lest things CXX undo the affect of
227 # 2) Need to explicitly set LTCXXCOMPILE so that EXTRA_CXX_FLAGS is
228 # last. (That way, things like -O2 passed down from the toplevel can
229 # be overridden by --enable-debug.)
