185# Libtool notes
186
187# 1) In general, libtool expects an argument such as `--tag=CXX' when
188# using the C++ compiler, because that will enable the settings
189# detected when C++ support was being configured.  However, when no
190# such flag is given in the command line, libtool attempts to figure
191# it out by matching the compiler name in each configuration section
192# against a prefix of the command line.  The problem is that, if the
193# compiler name and its initial flags stored in the libtool
194# configuration file don't match those in the command line, libtool
195# can't decide which configuration to use, and it gives up.  The
196# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
197# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
198# attempt to infer which configuration to use.
199# 
200# The second tag argument, `--tag disable-shared` means that libtool
201# only compiles each source once, for static objects. In actuality,
202# glibcxx_lt_pic_flag and glibcxx_compiler_shared_flag are added to
203# the libtool command that is used create the object, which is
204# suitable for shared libraries.  The `--tag disable-shared` must be
205# placed after --tag CXX lest things CXX undo the affect of
206# disable-shared.
207
208# 2) Need to explicitly set LTCXXCOMPILE so that EXTRA_CXX_FLAGS is
209# last. (That way, things like -O2 passed down from the toplevel can
210# be overridden by --enable-debug.)

219# 3) We'd have a problem when building the shared libstdc++ object if
220# the rules automake generates would be used.  We cannot allow g++ to
221# be used since this would add -lstdc++ to the link line which of
222# course is problematic at this point.  So, we get the top-level
