However, when no 176# such flag is given in the command line, libtool attempts to figure 177# it out by matching the compiler name in each configuration section 178# against a prefix of the command line. The problem is that, if the 179# compiler name and its initial flags stored in the libtool 180# configuration file don't match those in the command line, libtool 181# can't decide which configuration to use, and it gives up. The 182# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe 183# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to 184# attempt to infer which configuration to use. 185# 186# The second tag argument, `--tag disable-shared` means that libtool 187# only compiles each source once, for static objects. In actuality, 188# glibcxx_lt_pic_flag and glibcxx_compiler_shared_flag are added to 189# the libtool command that is used create the object, which is 190# suitable for shared libraries. The `--tag disable-shared` must be 191# placed after --tag CXX lest things CXX undo the affect of 192# disable-shared. 193 194# 2) Need to explicitly set LTCXXCOMPILE so that EXTRA_CXX_FLAGS is 195# last. (That way, things like -O2 passed down from the toplevel can 196# be overridden by --enable-debug.) 197LTCXXCOMPILE = \ 198 $(LIBTOOL) --tag CXX --tag disable-shared \ 199 $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS) \ 200 --mode=compile $(CXX) $(TOPLEVEL_INCLUDES) \ 201 $(AM_CPPFLAGS) $(CPPFLAGS) $(AM_CXXFLAGS) $(CXXFLAGS) $(EXTRA_CXX_FLAGS) 202 203LTLDFLAGS = $(shell $(SHELL) $(top_srcdir)/../libtool-ldflags $(LDFLAGS)) 204 205# 3) We'd have a problem when building the shared libstdc++ object if 206# the rules automake generates would be used. We cannot allow g++ to 207# be used since this would add -lstdc++ to the link line which of 208# course is problematic at this point.
