CARES_VERSION_INFO="20:0:18" |
|
dnl This flag accepts an argument of the form current[:revision[:age]]. So, |
|
dnl passing -version-info 3:12:1 sets current to 3, revision to 12, and age to |
|
dnl 1. |
|
dnl |
|
dnl If either revision or age are omitted, they default to 0. Also note that age |
|
dnl must be less than or equal to the current interface number. |
|
dnl |
|
dnl Here are a set of rules to help you update your library version information: |
|
dnl |
|
dnl 1.Start with version information of 0:0:0 for each libtool library. |
|
dnl |
|
dnl 2.Update the version information only immediately before a public release of |
|
dnl your software. More frequent updates are unnecessary, and only guarantee |
|
dnl that the current interface number gets larger faster. |
|
dnl |
|
dnl 3.If the library source code has changed at all since the last update, then |
|
dnl increment revision (c:r+1:a) |
|
dnl |
|
dnl 4.If any interfaces have been added, removed, or changed since the last |
|
dnl update, increment current, and set revision to 0. (c+1:r=0:a) |
|
dnl |
|
dnl 5.If any interfaces have been added since the last public release, then |
|
dnl increment age. (c:r:a+1) |
|
dnl |
|
dnl 6.If any interfaces have been removed since the last public release, then |
|
dnl set age to 0. (c:r:a=0) |

dnl Like AC_DEFINE_UNQUOTED this macro will define a C preprocessor |

dnl files. This macro, unlike AC_DEFINE_UNQUOTED, does not use a third |

dnl argument for the description. Symbol definitions done with this |
|
dnl macro are intended to be exclusively used in handcrafted *.h.in |
|
dnl template files. Contrary to what AC_DEFINE_UNQUOTED does, this one |
|
dnl prevents autoheader generation and insertion of symbol template |
|
dnl stub and definition into the first configuration header file. Do |
|
dnl not use this macro as a replacement for AC_DEFINE_UNQUOTED, each |
|
dnl one serves different functional needs. |

dnl Use AC_CHECK_DECL not AC_CHECK_FUNCS, while this doesn't do a linkage test, |

dnl it just makes sure the headers define it, this is the only thing without |

dnl a complex workaround on Windows that will do what we need. See: |

dnl https://github.com/msys2/msys2/wiki/Porting/f87a222118b1008ebc166ad237f04edb759c8f4c#calling-conventions-stdcall-and-autotools |

dnl https://lists.gnu.org/archive/html/autoconf/2013-05/msg00085.html |

dnl and for a more complex workaround, we'd need to use AC_LINK_IFELSE like: |

dnl https://mailman.videolan.org/pipermail/vlc-devel/2015-March/101802.html |
|
dnl which would require we check each individually and provide function arguments |
