Have you considered using Xvfb as minimal X-Server without visual

Service-Applications developed in Delphi (which haven't been ported to
fpc yet) on our linux server and it works fine.
I could do this, and I could put VNC as well. But I don't want that:
a web-application (or indeed any service application) should not have
dependencies on a GUI; this is a matter of design principle.
The same goes for a reporting engine. The core of the engine
should be totally free of GUI dependencies. I know only 2 engines which
satisfy this requirement: JasperReports and Morfik's reporting engine.
(those are the ones which I know, this doesn't mean there are no other
ones).

Hi, I'm planning to migrate a desktop app from Delphi to fcl-web, and
one important aspect of it, is the reporting engine. This app has many
reports created with FastReport 4, and I want to let the new app
generate PDFs on the fly.
If this is not possible, what do you recommend to create PDF reports
from Lazarus/FPC?
I researched this myself, but there is no clear answer.
It certainly depends on the platform. Linux/Windows ? On Linux, the
existing reporting engines rely on an X-server, which is not very good
for a web application. (our servers have no X installed). For example,
some people seem to have FastReport 4 running in FPC, so this is good,
but requires X and is not suitable for a webserver.
