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.

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.
