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.) 211LTCXXCOMPILE = \ 212 $(LIBTOOL) --tag CXX --tag disable-shared \ 213 $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS) \ 214 --mode=compile $(CXX) $(TOPLEVEL_INCLUDES) \ 215 $(AM_CPPFLAGS) $(CPPFLAGS) $(AM_CXXFLAGS) $(CXXFLAGS) $(EXTRA_CXX_FLAGS) 216 217LTLDFLAGS = $(shell $(SHELL) $(top_srcdir)/../libtool-ldflags $(LDFLAGS)) 218 219# 3) We'd have a problem when building the shared libstdc++ object if 220# the rules automake generates would be used.
