Move to the top so anyone changing the library version will have a higher likelihood of noticing them and thinking if they need changes as well. Added the rules, copied from libtool's info page, as a reminder. Added some obvious docs for the already defined SPICE_MICRO, SPICE_MINOR and SPICE_MAJOR. --- configure.ac | 36 +++++++++++++++++++++++++++++++++++- 1 file changed, 35 insertions(+), 1 deletion(-) diff --git a/configure.ac b/configure.ac index 66f9d12..abe9092 100644 --- a/configure.ac +++ b/configure.ac @@ -1,8 +1,42 @@ AC_PREREQ([2.57]) +# Making releases: +# Increment SPICE_MICRO if no interface change has been done +# Increment SPICE_MINOR and zero SPICE_MICRO if new backward compatible +# interfaces have been added. +# Increment SPICE_MAJOR and zero both SPICE_MINOR and SPICE_MICRO if non +# backward compatible changes (interface changed or removed). +# +# *additionally* follow the rules below for the libtool version. + m4_define([SPICE_MAJOR], 0) m4_define([SPICE_MINOR], 10) m4_define([SPICE_MICRO], 1) +# See info libtool or http://www.gnu.org/software/libtool/manual/html_node/Updating-version-info.html +# Here are the 6 rules: (rule 1 here just to avoid saying what I omitted) + +# 1.
