Hello,

I am running openSUSE Leap 42.1

> rpm -q syslog-ng-devel
syslog-ng-devel-3.7.1-1.1.x86_64

When I try to use provided development files to compile I see the following:

In file included from /usr/include/syslog-ng/persist-state.h:28:0,
                 from /home/matwey/lab/syslog-ng-persist/src/main.c:5:
/usr/include/syslog-ng/syslog-ng.h:28:20: fatal error: config.h: No such file
or directory
 #include <config.h>
                    ^
compilation terminated.

It seems that config.h file is missed from the package and the package is
useless now. In newer syslog-ng releases, this file has been renamed to
syslog-ng-config.h, see commit aa1f1b931ab7a17e97087a20956730c9ad6ead83 in
upstream.
