However, when no 168# such flag is given in the command line, libtool attempts to figure 169# it out by matching the compiler name in each configuration section 170# against a prefix of the command line. The problem is that, if the 171# compiler name and its initial flags stored in the libtool 172# configuration file don't match those in the command line, libtool 173# can't decide which configuration to use, and it gives up. The 174# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe 175# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to 176# attempt to infer which configuration to use. 177# 178# The second tag argument, `--tag disable-shared` means that libtool 179# only compiles each source once, for static objects. In actuality, 180# glibcxx_lt_pic_flag and glibcxx_compiler_shared_flag are added to 181# the libtool command that is used create the object, which is 182# suitable for shared libraries. The `--tag disable-shared` must be 183# placed after --tag CXX lest things CXX undo the affect of 184# disable-shared. 185 186# 2) Need to explicitly set LTCXXCOMPILE so that EXTRA_CXX_FLAGS is 187# last. (That way, things like -O2 passed down from the toplevel can 188# be overridden by --enable-debug.) 189LTCXXCOMPILE = \ 190 $(LIBTOOL) --tag CXX --tag disable-shared \ 191 $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS) \ 192 --mode=compile $(CXX) $(TOPLEVEL_INCLUDES) \ 193 $(AM_CPPFLAGS) $(CPPFLAGS) $(AM_CXXFLAGS) $(CXXFLAGS) $(EXTRA_CXX_FLAGS) 194 195LTLDFLAGS = $(shell $(SHELL) $(top_srcdir)/../libtool-ldflags $(LDFLAGS)) 196 197# 3) We'd have a problem when building the shared libstdc++ object if 198# the rules automake generates would be used.
