Hi all,

I have just succeeded over the weekend to compile SYSTEM.PAS, STRINGS.PAS, AND OBJECTS.PAS with CygWin. This has required some $IFDEFs and the addition of some new functions, just for CygWin - (so, AFAIK, the SYSTEM unit in BPCompat now compiles correctly under DJGPP, EMX, Linux, and CygWin - any other successes?)

One thing which I am missing is the Win32 API in Pascal. Has anyone translated any of the CygWin32 C headers (esp. any Win32 API calls) to GPC? I would like to start a collection of these. Better still, is anyone willing to write a program that will parse a CygWin32 C headers and generate a GPC unit from it?

I have converted just enough headers to be able to compile a basic GUI application, where you do all the message handling yourself (no object windows available :-(

I did this for cygwin32 b16. Then I focussed more on the unix ascpects for some time, but now I have a b18 GPC compiler, and I'm working on some cygwin32 things (DLL's, building the RTS as a DLL etc.) I'm not sure that function attibutes survive through the GPI mechanism (they didn't for b16) so using units may not be possible. You need the "__attribute__((stdcall))" feature to access win32 API functions.

Building DLL's on doze95 is difficult (not just for GPC) in b18. NT seemed fine, but my NT machine crashed a HD this weekend :-(

PS: I have found that many things are different under CygWin from the rest (e.g., the "stat" structure; the "errno", which is implemented as a macro); and many things which are in standard C headers are missing (e.g., strlwr(), strupr(), stricmp, etc.).

cygwin32 is basically BSD. I don't know about the unix (?) that cygwin32 differs from in your opinion, but Linux for instance is a SYSV like unix.
