However, when no 89# such flag is given in the command line, libtool attempts to figure 90# it out by matching the compiler name in each configuration section 91# against a prefix of the command line. The problem is that, if the 92# compiler name and its initial flags stored in the libtool 93# configuration file don't match those in the command line, libtool 94# can't decide which configuration to use, and it gives up. The 95# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe 96# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to 97# attempt to infer which configuration to use. 98# 99# The second tag argument, `--tag disable-shared` means that libtool 100# only compiles each source once, for static objects. In actuality, 101# glibcxx_lt_pic_flag and glibcxx_compiler_shared_flag are added to 102# the libtool command that is used create the object, which is 103# suitable for shared libraries. The `--tag disable-shared` must be 104# placed after --tag CXX lest things CXX undo the affect of 105# disable-shared. 106 107# 2) Need to explicitly set LTCXXCOMPILE so that EXTRA_CXX_FLAGS is 108# last. (That way, things like -O2 passed down from the toplevel can 109# be overridden by --enable-debug.) 110LTCXXCOMPILE = \ 111 $(LIBTOOL) --tag CXX --tag disable-shared \ 112 $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS) \ 113 --mode=compile $(CXX) $(TOPLEVEL_INCLUDES) \ 114 $(AM_CPPFLAGS) $(CPPFLAGS) $(AM_CXXFLAGS) $(CXXFLAGS) $(EXTRA_CXX_FLAGS) 115 116LTLDFLAGS = $(shell $(SHELL) $(top_srcdir)/../libtool-ldflags $(LDFLAGS)) 117 118# 3) We'd have a problem when building the shared libstdc++ object if 119# the rules automake generates would be used.
