# The statements below define a collection of symbols related to
|
|
# dynamic loading and shared libraries:
|
|
#
|
|
# 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.
|
|
# LD_FLAGS - 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_INSTALL_DIR in the Makefile.
|
|
# MAKE_LIB - Command to execute to build the Tcl library;
|
|
# differs depending on whether or not Tcl is being
|
|
# compiled as a shared 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_LIB_FILE - Name of the file that contains the Tcl library, such
|
|
# as libtcl7.5.so or libtcl7.5.a.
|
|
# TCL_LIB_SUFFIX -Specifies everything that comes after the "libtcl"
|
|
# in the 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 the Tcl shared library needs to have
|
|
# a .a extension whereas shared objects for loadable
|
|
# extensions have a .so extension. Defaults to
|
|
# ${VERSION}${SHLIB_SUFFIX}.
|
|
#--------------------------------------------------------------------
|
|
|
|
# Step 1: set the variable "system" to hold the name and version number
|
|
# for the system. This can usually be done via the "uname" command, but
|
|
# there are a few systems, like Next, where this doesn't work.
