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. -# -# We have to put --tag disable-shared after --tag CXX lest things -# CXX undo the affect of disable-shared. -LTCXXCOMPILE = $(LIBTOOL) --tag CXX --tag disable-shared \ - --mode=compile $(CXX) $(TOPLEVEL_INCLUDES) \ - $(AM_CPPFLAGS) $(CPPFLAGS) $(AM_CXXFLAGS) $(CXXFLAGS) - -LTLDFLAGS = $(shell $(SHELL) $(top_srcdir)/../libtool-ldflags $(LDFLAGS)) - -# 3) We'd have a problem when building the shared libstdc++ object if -# the rules automake generates would be used.
