Proposed patch.

Comment by Onlyjob [ 2013 Nov 29 ]

I would fix the issue by applying proposed patch and renaming 'configure.in' --> 'configure.ac'.

Please review.

Patch is already applied to Zabbix-2.2.0 in Debian "unstable".

Comment by Aleksandrs Saveljevs [ 2013 Dec 02 ]

Useful reading:

There is a discussion on KDE bug tracker regarding deprecation of "configure.in": https://bugs.kde.org/show_bug.cgi?id=111686#c2 . It says that "configure.ac" is the preferred file since around 2001 and autoconf change log confirms this (see http://git.savannah.gnu.org/gitweb/?p=autoconf.git;a=blob_plain;f=ChangeLog.2;hb=HEAD):

2000-12-23  Akim Demaille  <[email protected]>

	* autoconf.sh: Promote `configure.ac' over `configure.in'.
        * ...

So it should be safe to rename "configure.in" to "configure.ac" in 2.2 branch.

Comment by Aleksandrs Saveljevs [ 2013 Dec 02 ]

Fixed in development branch svn://svn.zabbix.com/branches/dev/ZBX-7227 .

In addition to Dmitry's patch, I have specified the first argument to AC_INIT() as "Zabbix" (note that it is capitalized). The reason is that the first link on AM_INIT_AUTOMAKE() above says that it should be package name, not tarball name, and tarball name is derived automatically from it.

Successfully tested

Comment by Aleksandrs Saveljevs [ 2013 Dec 09 ]

Fixed in pre-2.2.2rc1 r40844 and pre-2.3.0 (trunk) r40846.

Comment by richlv [ 2013 Dec 28 ]

current situation seems to result in warning with recent autotools :

warning: both `configure.ac' and `configure.in' are present.
warning: proceeding with `configure.ac'.

i assume that is intended to support older versions as well ?

Comment by Aleksandrs Saveljevs [ 2013 Dec 28 ]

No, this is not intended and it seems to be a problem with the merge into trunk.

Here is the list of changes in 2.2:

------------------------------------------------------------------------

It can be seen that in trunk configure.in was not removed for some reason.

Reopening to fix that.

Comment by Aleksandrs Saveljevs [ 2013 Dec 28 ]

Fixed directly in trunk (pre-2.3.0) in r41178. Please take a look.
