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 = \ 201 $(LIBTOOL) --tag CXX --tag disable-shared \ 202 $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS) \ 203 --mode=compile $(CXX) $(TOPLEVEL_INCLUDES) \ 204 $(AM_CPPFLAGS) $(CPPFLAGS) $(AM_CXXFLAGS) $(CXXFLAGS) $(EXTRA_CXX_FLAGS) 205 206LTLDFLAGS = $(shell $(SHELL) $(top_srcdir)/../libtool-ldflags $(LDFLAGS)) 207 208# 3) We'd have a problem when building the shared libstdc++ object if 209# the rules automake generates would be used.
