[fpc-pascal] Using Cairo lib on Linux without X
FPC has the API wrapper for Cairo lib. I am studying its dependencies and maybe use it in a Linux server with no X Window installed, for generating PDFs. Cairo is advertized to support multiple output devices, including X Window, image buffers, PostScript, PDF, and SVG file output. I understand it means that X Window is required only for the X Window backend. PDF or SVG backends should not require X Window. However on my Linux Mint 17 libcairo has a dependency for libX11.so.6.

So probably compiling libcairo.so yourself is the only option. Alternative for PDF generation, as I mentioned before to you I believe, fpGUI includes a very good PDF report engine which could easily work without depending on fpGUI or any GUI. Michael van Canneyt also created a PDF report engine (based on some of the code included in fpGUI), and I believe this is already in FPC Trunk (Michael?).
