# DL_LIBS - Library file(s) to include in tclsh and other base
987
# applications in order for the "load" command to work.
988
# LDFLAGS - Flags to pass to the compiler when linking object
989
# files into an executable application binary such
990
# as tclsh.
991
# LD_SEARCH_FLAGS-Flags to pass to ld, such as "-R /usr/local/tcl/lib",
992
# that tell the run-time dynamic linker where to look
993
# for shared libraries such as libtcl.so. Depends on
994

1000
# MAKE_LIB - Command to execute to build the a library;

# differs when building shared or static.
1002
# MAKE_STUB_LIB -
1003
# Command to execute to build a stub library.
1004
# INSTALL_LIB - Command to execute to install a library;
1005
# differs when building shared or static.
1006
# INSTALL_STUB_LIB -
1007
# Command to execute to install a stub library.
1008
# STLIB_LD - Base command to use for combining object files
1009
# into a static library.
1010
# SHLIB_CFLAGS - Flags to pass to cc when compiling the components
1011
# of a shared library (may request position-independent
1012
# code, among other things).
1013
# SHLIB_LD - Base command to use for combining object files
1014
# into a shared library.
1015
# SHLIB_LD_LIBS - Dependent libraries for the linker to scan when
1016
# creating shared libraries. This symbol typically
1017
# goes at the end of the "ld" commands that build
1018
# shared libraries. The value of the symbol is
1019
# "${LIBS}" if all of the dependent libraries should
1020
# be specified when creating a shared library. If
1021
# dependent libraries should not be specified (as on
1022
# SunOS 4.x, where they cause the link to fail, or in
1023
# general if Tcl and Tk aren't themselves shared
1024
# libraries), then this symbol has an empty string
1025
# as its value.
1026
# SHLIB_SUFFIX - Suffix to use for the names of dynamically loadable
1027
# extensions. An empty string means we don't know how
1028
# to use shared libraries on this platform.
1029
# TCL_SHLIB_LD_EXTRAS - Additional element which are added to SHLIB_LD_LIBS
1030
# TK_SHLIB_LD_EXTRAS for the build of Tcl and Tk, but not recorded in the
1031
# tclConfig.sh, since they are only used for the build
1032
# of Tcl and Tk.
1033
# Examples: MacOS X records the library version and
1034
# compatibility version in the shared library. But
1035
# of course the Tcl version of this is only used for Tcl.
1036
# LIB_SUFFIX - Specifies everything that comes after the "libfoo"
1037
# in a static or shared library name, using the $VERSION variable
1038
# to put the version in the right place. This is used
1039
# by platforms that need non-standard library names.
1040
# Examples: ${VERSION}.so.1.1 on NetBSD, since it needs
1041
# to have a version after the .so, and ${VERSION}.a
1042
# on AIX, since a shared library needs to have
1043
# a .a extension whereas shared objects for loadable
1044
# extensions have a .so extension. Defaults to
1045
# ${VERSION}${SHLIB_SUFFIX}.
1046
# TCL_LIBS -
1047
# Libs to use when linking Tcl shell or some other
1048
# shell that includes Tcl libs.
1049
# CFLAGS_DEBUG -
1050
# Flags used when running the compiler in debug mode
1051
# CFLAGS_OPTIMIZE -
1052
# Flags used when running the compiler in optimize mode
1053
# CFLAGS - Additional CFLAGS added as necessary (usually 64-bit)
