1034 # Try to determine the proper flags to pass to the compiler
1035 # for building shared libraries and other such nonsense.
1036 #
1037 # Arguments:
1038 # none
1039 #
1040 # Results:
1041 #
1042 # Defines and substitutes the following vars:
1043 #
1044 # DL_OBJS, DL_LIBS - removed for TEA, only needed by core.
1045 # LDFLAGS - Flags to pass to the compiler when linking object
1046 # files into an executable application binary such
1047 # as tclsh.
1048 # LD_SEARCH_FLAGS-Flags to pass to ld, such as "-R /usr/local/tcl/lib",
1049 # that tell the run-time dynamic linker where to look
1050 # for shared libraries such as libtcl.so. Depends on
1051 # the variable LIB_RUNTIME_DIR in the Makefile. Could
1052 # be the same as CC_SEARCH_FLAGS if ${CC} is used to link.
1053 # CC_SEARCH_FLAGS-Flags to pass to ${CC}, such as "-Wl,-rpath,/usr/local/tcl/lib",
1054 # that tell the run-time dynamic linker where to look
1055 # for shared libraries such as libtcl.so. Depends on
1056 # the variable LIB_RUNTIME_DIR in the Makefile.
1057 # SHLIB_CFLAGS - Flags to pass to cc when compiling the components
1058 # of a shared library (may request position-independent
1059 # code, among other things).
1060 # SHLIB_LD - Base command to use for combining object files
1061 # into a shared library.
1062 # SHLIB_LD_LIBS - Dependent libraries for the linker to scan when
1063 # creating shared libraries. This symbol typically
1064 # goes at the end of the "ld" commands that build
1065 # shared libraries. The value of the symbol defaults to
1066 # "${LIBS}" if all of the dependent libraries should
1067 # be specified when creating a shared library. If
1068 # dependent libraries should not be specified (as on
1069 # SunOS 4.x, where they cause the link to fail, or in
1070 # general if Tcl and Tk aren't themselves shared
1071 # libraries), then this symbol has an empty string
1072 # as its value.
1073 # SHLIB_SUFFIX - Suffix to use for the names of dynamically loadable
1074 # extensions. An empty string means we don't know how
1075 # to use shared libraries on this platform.
1076 # LIB_SUFFIX - Specifies everything that comes after the "libfoo"
1077 # in a static or shared library name, using the $PACKAGE_VERSION variable
1078 # to put the version in the right place. This is used
1079 # by platforms that need non-standard library names.
1080 # Examples: ${PACKAGE_VERSION}.so.1.1 on NetBSD, since it needs
1081 # to have a version after the .so, and ${PACKAGE_VERSION}.a
1082 # on AIX, since a shared library needs to have
1083 # a .a extension whereas shared objects for loadable
1084 # extensions have a .so extension. Defaults to
1085 # ${PACKAGE_VERSION}${SHLIB_SUFFIX}.
1086 # CFLAGS_DEBUG -
1087 # Flags used when running the compiler in debug mode
1088 # CFLAGS_OPTIMIZE -
1089 # Flags used when running the compiler in optimize mode
1090 # CFLAGS - Additional CFLAGS added as necessary (usually 64-bit)
