However, when no - # such flag is given in the command line, libtool attempts to figure - # it out by matching the compiler name in each configuration section - # against a prefix of the command line. The problem is that, if the - # compiler name and its initial flags stored in the libtool - # configuration file don't match those in the command line, libtool - # can't decide which configuration to use, and it gives up. The - # correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe - # CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to - # attempt to infer which configuration to use. - # - # The second tag argument, `--tag disable-shared` means that libtool - # only compiles each source once, for static objects. In actuality, - # glibcxx_lt_pic_flag and glibcxx_compiler_shared_flag are added to - # the libtool command that is used create the object, which is - # suitable for shared libraries. The `--tag disable-shared` must be - # placed after --tag CXX lest things CXX undo the affect of - # disable-shared. - - # 2) Need to explicitly set LTCXXCOMPILE so that EXTRA_CXX_FLAGS is - # last.
