# A note on compatibility and static libraries.
|
|
#
|
|
# static lib == linked against only this version, should not need compat
|
|
# shared lib == linked against potentially all compat versions
|
|
#
|
|
# Thus, the shared libs have more compat symbols, which can be found
|
|
# segregated in the sources with -D_GLIBCXX_SHARED.
|
|
#
|
|
# In the sub-directories of libsupc++, src/c++98, src/c++11, only
|
|
# -prefer-pic objects are generated for the convenience libraries.
|
|
#
|
|
# In the main src directory, make shared and static objects just for
|
|
# the compat libraries. Shared objects are compiled with -prefer-pic
|
|
# -D_GLIBCXX_SHARED and in the .libs sub-directory, static objects are
|
|
# compiled with -prefer-pic (ie, -fPIC but not -D_GLIBCXX_SHARED) and
|
|
# the main src directory.
|
|
#
|
|
# Why are objects destined for libstdc++.a compiled with -fPIC? First,
|
|
# because -fPIC is not harmful to use for objects destined for static
|
|
# libraries. In addition, using -fPIC will allow the use of static
|
|
# libstdc++.a in the creation of other C++ shared libraries.
|
|
|
|
# AM_CXXFLAGS needs to be in each sub-directory so that it can be
|
|
# modified in a per-library or per-sub-library way. Need to manually
|
|
# set this option because CONFIG_CXXFLAGS has to be after
|
|
# OPTIMIZE_CXXFLAGS on the compile line so that -O2 can be overridden
|
|
# as the occasion calls for it.

# Libtool notes
|
|
|
|
# 1) 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.
|
|
#
|
|
# The second tag argument, `--tag disable-shared` means that libtool
|
|
# only compiles each source once, for static objects. In actuality,
|
|
# glibcxx_lt_pic_flag and glibcxx_compiler_shared_flag are added to
|
|
# the libtool command that is used create the object, which is
|
|
# suitable for shared libraries. The `--tag disable-shared` must be
|
|
# placed after --tag CXX lest things CXX undo the affect of
|
|
# disable-shared.
|
|
|
|
# 2) Need to explicitly set LTCXXCOMPILE so that EXTRA_CXX_FLAGS is
|
|
# last. (That way, things like -O2 passed down from the toplevel can
|
|
# be overridden by --enable-debug and --enable-cxx-flags.)

|
|
|
|
# 3) We'd have a problem when building the shared libstdc++ object if
|
|
# the rules automake generates would be used. We cannot allow g++ to
|
|
# be used since this would add -lstdc++ to the link line which of
|
|
# course is problematic at this point. So, we get the top-level
