87 # 1) In general, libtool expects an argument such as `--tag=CXX' when
88 # using the C++ compiler, because that will enable the settings
89 # detected when C++ support was being configured. However, when no
90 # such flag is given in the command line, libtool attempts to figure
91 # it out by matching the compiler name in each configuration section
92 # against a prefix of the command line. The problem is that, if the
93 # compiler name and its initial flags stored in the libtool
94 # configuration file don't match those in the command line, libtool
95 # can't decide which configuration to use, and it gives up. The
96 # correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
97 # CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
98 # attempt to infer which configuration to use.
100 # The second tag argument, `--tag disable-shared` means that libtool
101 # only compiles each source once, for static objects. In actuality,
102 # glibcxx_lt_pic_flag and glibcxx_compiler_shared_flag are added to
103 # the libtool command that is used create the object, which is
104 # suitable for shared libraries. The `--tag disable-shared` must be
105 # placed after --tag CXX lest things CXX undo the affect of
108 # 2) Need to explicitly set LTCXXCOMPILE so that EXTRA_CXX_FLAGS is
109 # last. (That way, things like -O2 passed down from the toplevel can
110 # be overridden by --enable-debug.)
