However, when no 237# such flag is given in the command line, libtool attempts to figure 238# it out by matching the compiler name in each configuration section 239# against a prefix of the command line. The problem is that, if the 240# compiler name and its initial flags stored in the libtool 241# configuration file don't match those in the command line, libtool 242# can't decide which configuration to use, and it gives up. The 243# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe 244# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to 245# attempt to infer which configuration to use. 246# 247# The second tag argument, `--tag disable-shared` means that libtool 248# only compiles each source once, for static objects. In actuality, 249# glibcxx_lt_pic_flag and glibcxx_compiler_shared_flag are added to 250# the libtool command that is used create the object, which is 251# suitable for shared libraries. The `--tag disable-shared` must be 252# placed after --tag CXX lest things CXX undo the affect of 253# disable-shared. 254 255# 2) Need to explicitly set LTCXXCOMPILE so that EXTRA_CXX_FLAGS is 256# last. (That way, things like -O2 passed down from the toplevel can 257# be overridden by --enable-debug.) 258LTCXXCOMPILE = \ 259 $(LIBTOOL) --tag CXX --tag disable-shared \ 260 $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS) \ 261 --mode=compile $(CXX) $(TOPLEVEL_INCLUDES) \ 262 $(AM_CPPFLAGS) $(CPPFLAGS) $(AM_CXXFLAGS) $(CXXFLAGS) $(EXTRA_CXX_FLAGS) 263 264LTLDFLAGS = $(shell $(SHELL) $(top_srcdir)/../libtool-ldflags $(LDFLAGS)) 265 266# 3) We'd have a problem when building the shared libstdc++ object if 267# the rules automake generates would be used. We cannot allow g++ to 268# be used since this would add -lstdc++ to the link line which of 269# course is problematic at this point.
