947 | # differs when building shared or static. | |
948 | # INSTALL_STUB_LIB - | |

950 | # STLIB_LD - Base command to use for combining object files | |
951 | # into a static library. | |
952 | # SHLIB_CFLAGS - Flags to pass to cc when compiling the components | |
953 | # of a shared library (may request position-independent | |
954 | # code, among other things). | |
955 | # SHLIB_LD - Base command to use for combining object files | |
956 | # into a shared library. | |
957 | # SHLIB_LD_LIBS - Dependent libraries for the linker to scan when | |
958 | # creating shared libraries. This symbol typically | |
959 | # goes at the end of the "ld" commands that build | |
960 | # shared libraries. The value of the symbol is | |
961 | # "${LIBS}" if all of the dependent libraries should | |
962 | # be specified when creating a shared library. If | |
963 | # dependent libraries should not be specified (as on | |
964 | # SunOS 4.x, where they cause the link to fail, or in | |
965 | # general if Tcl and Tk aren't themselves shared | |
966 | # libraries), then this symbol has an empty string | |
967 | # as its value. | |
968 | # SHLIB_SUFFIX - Suffix to use for the names of dynamically loadable | |
969 | # extensions. An empty string means we don't know how | |
970 | # to use shared libraries on this platform. | |
971 | # TCL_SHLIB_LD_EXTRAS - Additional element which are added to SHLIB_LD_LIBS | |
972 | # TK_SHLIB_LD_EXTRAS for the build of Tcl and Tk, but not recorded in the | |
973 | # tclConfig.sh, since they are only used for the build | |
974 | # of Tcl and Tk. | |
975 | # Examples: MacOS X records the library version and | |
976 | # compatibility version in the shared library. But | |
977 | # of course the Tcl version of this is only used for Tcl. | |
978 | # LIB_SUFFIX - Specifies everything that comes after the "libfoo" | |
979 | # in a static or shared library name, using the $VERSION variable | |
980 | # to put the version in the right place. This is used | |
981 | # by platforms that need non-standard library names. | |
982 | # Examples: ${VERSION}.so.1.1 on NetBSD, since it needs | |
983 | # to have a version after the .so, and ${VERSION}.a | |
984 | # on AIX, since a shared library needs to have | |
985 | # a .a extension whereas shared objects for loadable | |
986 | # extensions have a .so extension. Defaults to | |
987 | # ${VERSION}${SHLIB_SUFFIX}. | |
988 | # TCL_NEEDS_EXP_FILE - | |
989 | # 1 means that an export file is needed to link to a | |
990 | # shared library. | |
991 | # TCL_EXP_FILE - The name of the installed export / import file which | |
992 | # should be used to link to the Tcl shared library. | |
993 | # Empty if Tcl is unshared. | |
994 | # TCL_BUILD_EXP_FILE - | |
995 | # The name of the built export / import file which | |
996 | # should be used to link to the Tcl shared library. | |
997 | # Empty if Tcl is unshared. | |
998 | # CFLAGS_DEBUG - | |
999 | # Flags used when running the compiler in debug mode | |
1000 | # CFLAGS_OPTIMIZE - | |
1001 | # Flags used when running the compiler in optimize mode | |
1002 | # CFLAGS - Additional CFLAGS added as necessary (usually 64-bit) | |
