From 4378b8ded4004249ad13e24873c47b0627a6a1bd Mon Sep 17 00:00:00 2001 From: Chris Reuter Date: Mon, 4 Nov 2013 17:11:33 -0500 Subject: gd.h now holds the canonical version number. Up to now, the version numbers were defined in configure.ac and put into gd.h by generating it from gd.h.in, replacing the values of several C macros. This violates the DRY principle, won't work on a dumb build system, confuses some dev tools and is just a huge headache in general. This change makes gd.h (no longer generated) the home of the version number and provides a script (config/getver.pl) which can extract the requested version components from the header file. configure.ac now gets the version number from gd.h instead of vice versa. In addition, there are now C functions that return the values of the version macros. This is for the benefit of non-C code using the library without access to the header file. It also provides a way to get the version number of the library currently linked rather than the header the program was compiled against. (This could change if the shared library is updated without recompiling the program using it.) --- config/getver.pl | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100755 config/getver.pl (limited to 'config') diff --git a/config/getver.pl b/config/getver.pl new file mode 100755 index 0000000..9118a5b --- /dev/null +++ b/config/getver.pl @@ -0,0 +1,29 @@ +#!/usr/bin/env perl + +# Simple script to extract the version number parts from +# src/version.h.
