# LD_SEARCH_FLAGS-Flags to pass to ld, such as "-R /usr/local/tcl/lib", |

|
# 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 |

|
# 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 |

# Examples: MacOS X records the library version and |

# 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_NEEDS_EXP_FILE - |
