# 1) Need to explicitly set LTCXXCOMPILE so that AM_CXXFLAGS is

|
# last. (That way, things like -O2 passed down from the toplevel can
|
|
# be overridden by --enable-debug.)
|
|
|
|
# 2) In general, libtool expects an argument such as `--tag=CXX' when
|
|
# using the C++ compiler, because that will enable the settings
|
|
# detected when C++ support was being configured. However, when no
|
|
# such flag is given in the command line, libtool attempts to figure
|
|
# it out by matching the compiler name in each configuration section
|
|
# against a prefix of the command line. The problem is that, if the
|
|
# compiler name and its initial flags stored in the libtool
|
|
# configuration file don't match those in the command line, libtool
|
|
# can't decide which configuration to use, and it gives up. The
|
|
# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
|
|
# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
|
|
# attempt to infer which configuration to use.
|
|
#
|
|
# We have to put --tag disable-shared after --tag CXX lest things
|
|
# CXX undo the affect of disable-shared.

|
|
# 3) We have a problem when building the shared libstdc++ object if
|
|
# the rules automake generates would be used. We cannot allow CXX to
|
|
# be used in libtool since this would add -lstdc++ to the link line
|
|
# which of course is problematic at this point.
