[Lazarus] Free Pascal / Lazarus calling conventions

Hi guys, Just a stupid question, but is the Lazarus calling conventions documented anywhere? Is it different from Delphi calling conventions? When calling external c functions from libraries, does one need any special declarations like in Delphi to tell it to use c-style calling conventions?

[Lazarus] Lazarus for mobile development?

Hi guys, I need to know if I can use Lazarus for mibile development on Android, Windows mobile and iOS (iPhone)? I currently use a program (written in Delphi, I think) that runs only on Android and Windows mobile (and Palm OS?) called CyberTracker, which uses MS access (.MDB) files to store both

[Lazarus] How to access libraries from other languages?

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

[Lazarus] How to access C and C++ libraries?

Hi everybody! Years ago I used Delphi (on Windows) to access a C or C++ API (for talking directly with embedded device) and I can remember that there were a number of gotchas (e.g. the calling convention had to be changed form Pascal to something else (extern?) etc. ). Now I am wondering about
