174# Libtool notes
175
176# 1) In general, libtool expects an argument such as `--tag=CXX' when
177# using the C++ compiler, because that will enable the settings
178# detected when C++ support was being configured.  However, when no
179# such flag is given in the command line, libtool attempts to figure
180# it out by matching the compiler name in each configuration section
181# against a prefix of the command line.  The problem is that, if the
182# compiler name and its initial flags stored in the libtool
183# configuration file don't match those in the command line, libtool
184# can't decide which configuration to use, and it gives up.  The
185# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
186# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
187# attempt to infer which configuration to use.
188#
189# The second tag argument, `--tag disable-shared` means that libtool
190# only compiles each source once, for static objects. In actuality,
191# glibcxx_lt_pic_flag and glibcxx_compiler_shared_flag are added to
192# the libtool command that is used create the object, which is
193# suitable for shared libraries.  The `--tag disable-shared` must be
194# placed after --tag CXX lest things CXX undo the affect of
195# disable-shared.
196
197# 2) Need to explicitly set LTCXXCOMPILE so that EXTRA_CXX_FLAGS is
198# last. (That way, things like -O2 passed down from the toplevel can
199# be overridden by --enable-debug.)
200LTCXXCOMPILE = \

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

213# compilation driver.
