Hi, I don't know about v3.6.2, but we only install the headers of syslog-ng-core (libsyslog-ng), which is necessary for plugin development. The headers of modules are not installed, because currently plugins are not used as libraries by other plugins/projects. So, for example, you can find the old "syslog-ng/tags.h" header at its new place: "syslog-ng/logmsg/tags.h", but you won't find "modules/dbparser/patterndb-int.h" installed, you'll have to use the source code. -- László Várady ________________________________ From: syslog-ng <syslog-ng-bounces@lists.balabit.hu> on behalf of Nitish Saboo <nitish.saboo55@gmail.com> Sent: Monday, February 3, 2020 13:04 To: Syslog-ng users' and developers' mailing list <syslog-ng@lists.balabit.hu> Subject: [syslog-ng] Not finding header files in syslog-ng-3.25.1 as compared to syslog-ng-3.6.2 CAUTION: This email originated from outside of the organization.
