# Try to determine the proper flags to pass to the compiler
# for building shared libraries and other such nonsense.
#
# Arguments:
# none
#
# Results:
#
# Defines and substitutes the following vars:
#
# DL_OBJS - Name of the object file that implements dynamic
# loading for Tcl on this system.
# DL_LIBS - Library file(s) to include in tclsh and other base
# applications in order for the "load" command to work.
# LDFLAGS - Flags to pass to the compiler when linking object
# files into an executable application binary such
# as tclsh.
# LD_SEARCH_FLAGS-Flags to pass to ld, such as "-R /usr/local/tcl/lib",
# that tell the run-time dynamic linker where to look
# for shared libraries such as libtcl.so. Depends on
# the variable LIB_RUNTIME_DIR in the Makefile. Could
# be the same as CC_SEARCH_FLAGS if ${CC} is used to link.
# CC_SEARCH_FLAGS-Flags to pass to ${CC}, such as "-Wl,-rpath,/usr/local/tcl/lib",
# that tell the run-time dynamic linker where to look
# for shared libraries such as libtcl.so. Depends on
# the variable LIB_RUNTIME_DIR in the Makefile.
# MAKE_LIB - Command to execute to build the a library;
# differs when building shared or static.
# MAKE_STUB_LIB -
# Command to execute to build a stub library.
# INSTALL_LIB - Command to execute to install a library;
# differs when building shared or static.
# INSTALL_STUB_LIB -
# Command to execute to install a stub library.
# STLIB_LD - Base command to use for combining object files
# into a static library.
# SHLIB_CFLAGS - Flags to pass to cc when compiling the components
# of a shared library (may request position-independent
# code, among other things).
# SHLIB_LD - Base command to use for combining object files
# into a shared library.
# SHLIB_LD_LIBS - Dependent libraries for the linker to scan when
# creating shared libraries. This symbol typically
# goes at the end of the "ld" commands that build
# shared libraries. The value of the symbol is
# "${LIBS}" if all of the dependent libraries should
# be specified when creating a shared library. If
# dependent libraries should not be specified (as on
# SunOS 4.x, where they cause the link to fail, or in
# general if Tcl and Tk aren't themselves shared
# libraries), then this symbol has an empty string
# as its value.
# SHLIB_SUFFIX - Suffix to use for the names of dynamically loadable
# extensions. An empty string means we don't know how
# to use shared libraries on this platform.
# TCL_SHLIB_LD_EXTRAS - Additional element which are added to SHLIB_LD_LIBS
# TK_SHLIB_LD_EXTRAS for the build of Tcl and Tk, but not recorded in the
# tclConfig.sh, since they are only used for the build
# of Tcl and Tk.
# Examples: MacOS X records the library version and
# compatibility version in the shared library. But
# of course the Tcl version of this is only used for Tcl.
# LIB_SUFFIX - Specifies everything that comes after the "libfoo"
# in a static or shared library name, using the $VERSION variable
# to put the version in the right place. This is used
# by platforms that need non-standard library names.
# Examples: ${VERSION}.so.1.1 on NetBSD, since it needs
# to have a version after the .so, and ${VERSION}.a
# on AIX, since a shared library needs to have
# a .a extension whereas shared objects for loadable
# extensions have a .so extension. Defaults to
# ${VERSION}${SHLIB_SUFFIX}.
# TCL_LIBS -
# Libs to use when linking Tcl shell or some other
# shell that includes Tcl libs.
# CFLAGS_DEBUG -
# Flags used when running the compiler in debug mode
# CFLAGS_OPTIMIZE -
# Flags used when running the compiler in optimize mode
# CFLAGS - Additional CFLAGS added as necessary (usually 64-bit)
