Re: [fpc-pascal] Using Cairo lib on Linux without X
FYI, I got ssh access to a Linux server and tested a program made with Lazarus CairoCancas with NoGui widgetset. The machine had Mint Linux and libcairo was installed. X11 was installed, too, but not running. ldd shows libcairo depends on X11. The program amazingly works! It builds a PDF file with Unicode text in different languages. The program can be found in lazarus/components/cairocanvas/examples in case somebody wants to try it.

[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.
