Linux daemon for a Ubuntu server
« on: October 27, 2016, 10:11:40 am »
Hi.

I want to create a daemon for a Ubuntu server. (No graphical)

I need to compile it using ONLY free pascal compiler 3.0

If I use a TCustomDaemon (like tutorial http://wiki.freepascal.org/Daemons_and_Services ) then free pascal tells that units are not found... a TCustomDaemon can only be compiled through lazarus?
Is it possible to compile it without lazarus, only pure free pascal compiler?

Thanks

There is an example in the ./packages/rtl-extra/examples directory that is absolutely cross-platform.

Object Pascal programmers should get rid of their "component fetish" especially with the non-visuals.

You can use lazbuild utility to compile Lazarus project without Lazarus.

I think the man is talking about ONLY Freepascal - so without Lazarus.

Correct. And also has the pointer to a Laz-free example. Daemons don't need Lazarus at all.

app is working good... but.

How to install it as a service on Linux?  (now, when I close ssh connection app stops)

option -i does not do anything on Linux (explained at http://www.freepascal.org/~michael/articles/daemons/daemons.pdf ) so my question is how to install a fpc app made as a service in Linux to start/stop unatended like Windows does?

Thanks

Daemon installation depends on init system. upstart, systemd, openrc, etc. all use different ways. What's yours?
