Description Christian Heimes 2017-01-11 15:42:47 UTC
Description of problem:
/usr/include/dirsrv/slapi-plugin.h contains an invalid function prototype

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Compile any component that includes slapi-plugin.h, e.g. FreeIPA

Actual results:
make[4]: Entering directory '/usr/src/freeipa/daemons/ipa-slapi-plugins/ipa-lockout'

/usr/include/dirsrv/slapi-plugin.h:6292:1: warning: function declaration isn’t a prototype [-Wstrict-prototypes]
 const char * slapi_get_cacertfile();

Expected results:
No warning

Additional info:
The correct function prototype is
const char * slapi_get_cacertfile( void );

Comment 1 Rich Megginson 2017-01-11 16:13:39 UTC
I think this is not an openldap issue since you're using /usr/include/dirsrv/slapi-plugin.h which is a 389-ds-base-devel file.

Comment 2 Christian Heimes 2017-01-11 16:21:02 UTC
Ah, you are right. I selected the wrong component. Thanks Rich!

Comment 3 Noriko Hosoi 2017-01-11 17:11:24 UTC
Thanks, Christian!

The issue has been addressed and fixed in the master branch with this patch:

commit 5b0c9c0a90b73f0b1a200d9ccb1209ccc5dcd7e3
Author: Lukas Slebodnik <lslebodn@redhat.com>
Date:   Fri Sep 2 15:10:44 2016 +0000

    Ticket 48979 - Allow to compile 389ds with warning Wstrict-prototypes

The change is going to be in 389-ds-base-1.3.6 release.  So far, we have no plan to backport the patch to 1.3.5.  Is it ok with you or too late?

Comment 4 Christian Heimes 2017-01-12 15:40:36 UTC
It's just a warning and it's not going to cause any trouble soon. I can wait for 1.3.6.
