[Tfug] How do I get automake to set build number?

[Andrew Ayre]

I use subversion for all software development. It is possible to commit and
then automatically insert the revision number into a #define, which then can
be used any way you like. The advantage is that it is automatic and allows
you to tie a release to a specific subversion revision.

Hello -

I've been using KDevelop with the GNU automake stuff.

I would really like to get a build number into a version string.

Besides not knowing how to get it to update a version string, I don't even
know where it's keeping the data for the version string. I just haven't
gotten that deep into the automagic I guess.

I could put a line into the makefile, but automake remakes that.

I visual studio, I made an app that would parse a version.h file that I had
for every project, and increment the build number.  In versio.h I had
several defines for the various version string fields that winders liked to
have:

#ifndef VERSION_H
#define VERSION_H

#define FILE_VERSION   1, 1, 0, 31
#define PROD_VERSION   1, 1, 0, 31
#define FILE_VER_STR   "1, 1, 0, 31"
#define PROD_VER_STR   "1, 1, 0, 31"

#endif


I was able to set pre-build events in a project.  The event would call my
utility, something like:  incbuild version.h
Every build then had a unique version string, and when frantically figuring
out what version of code was being tested and running on what machine, it
really saved me, if I saved the code.

Linux seems to mess with file dates differently than winders, unless I need
to look at a different date of a file so I can track it.  It seems modified
and accessed are for the specific copy of a file, not the original one.

Anyway --

Does anyone out there have a good method of identifying the specific build
of an application?

Thanks

Joe
