Hi guys,
The recent threat on Raspberry libraries made me think. I remember that
it was possible in Delphi to access .ddl libraries written in C or C++
(a bit more work) by wrapping them and using a "far" call? I did this a
while ago, so not clear on the details anymore. Typically I would write
a driver etc. for hardware in C/C++ and then have a Delphi wrapper class
that I could use to access the hardware. I assume this is still possible
in Lazarus? Are there any tutorials etc. or will the old Delphi methods
still work? Will this also work with Linux .so files? For that matter,
are there any other way for Lazarus to get direct access to the hardware
(except maybe use inline assembler)?
Thanks for bringing me back up to speed!
C libraries are no problem. In fact we have many import units for
various C libraries (e.g. X11, Gtk, etc.). C++ is more problematic. In
theory the compiler contains support for C++ classes, but that is
nowhere near usable currently so a C++ API needs to be flattened to a
C one like is done with the Qt libraries.
Regards,
Sven
