(That way, things like -O2 passed down from the toplevel can 121# be overridden by --enable-debug.) 122 123# 2) In general, libtool expects an argument such as `--tag=CXX' when 124# using the C++ compiler, because that will enable the settings 125# detected when C++ support was being configured. However, when no 126# such flag is given in the command line, libtool attempts to figure 127# it out by matching the compiler name in each configuration section 128# against a prefix of the command line. The problem is that, if the 129# compiler name and its initial flags stored in the libtool 130# configuration file don't match those in the command line, libtool 131# can't decide which configuration to use, and it gives up. The 132# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe 133# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to 134# attempt to infer which configuration to use. 135# 136# We have to put --tag disable-shared after --tag CXX lest things 137# CXX undo the affect of disable-shared. 138LTCXXCOMPILE = $(LIBTOOL) --tag CXX --tag disable-shared \ 139 --mode=compile $(CXX) $(TOPLEVEL_INCLUDES) \ 140 $(AM_CPPFLAGS) $(CPPFLAGS) $(AM_CXXFLAGS) $(CXXFLAGS) 141 142LTLDFLAGS = $(shell $(SHELL) $(top_srcdir)/../libtool-ldflags $(LDFLAGS)) 143 144# 3) We'd have a problem when building the shared libstdc++ object if 145# the rules automake generates would be used. We cannot allow g++ to 146# be used since this would add -lstdc++ to the link line which of 147# course is problematic at this point.
