However, when no 148# such flag is given in the command line, libtool attempts to figure 149# it out by matching the compiler name in each configuration section 150# against a prefix of the command line. The problem is that, if the 151# compiler name and its initial flags stored in the libtool 152# configuration file don't match those in the command line, libtool 153# can't decide which configuration to use, and it gives up. The 154# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe 155# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to 156# attempt to infer which configuration to use. 157# 158# The second tag argument, `--tag disable-shared` means that libtool 159# only compiles each source once, for static objects. In actuality, 160# glibcxx_lt_pic_flag and glibcxx_compiler_shared_flag are added to 161# the libtool command that is used create the object, which is 162# suitable for shared libraries. The `--tag disable-shared` must be 163# placed after --tag CXX lest things CXX undo the affect of 164# disable-shared. 165 166# 2) Need to explicitly set LTCXXCOMPILE so that EXTRA_CXX_FLAGS is 167# last. (That way, things like -O2 passed down from the toplevel can 168# be overridden by --enable-debug.) 169LTCXXCOMPILE = \ 170 $(LIBTOOL) --tag CXX --tag disable-shared \ 171 $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS) \ 172 --mode=compile $(CXX) $(TOPLEVEL_INCLUDES) \ 173 $(AM_CPPFLAGS) $(CPPFLAGS) $(AM_CXXFLAGS) $(CXXFLAGS) $(EXTRA_CXX_FLAGS) 174 175LTLDFLAGS = $(shell $(SHELL) $(top_srcdir)/../libtool-ldflags $(LDFLAGS)) 176 177# 3) We'd have a problem when building the shared libstdc++ object if 178# the rules automake generates would be used. We cannot allow g++ to 179# be used since this would add -lstdc++ to the link line which of 180# course is problematic at this point.
