Hi ,
I'm porting dosbox 0.72 in Solaris. I have made some minor changes in dosbox source file. So is it looks fine with you guys?
Pls. let me know your feedback.

The changes are :

Maybe use the 0.73 sources though 😀

For me the compilation process was as straightforward as for linux when
i tried it a good while ago, some keyboard issue (scancodes wrong) but
otherwise sort of working.

Feel free to keep us informed in this thread.

Thanks a lot for your reply.
I have already ported dosbox-0.73 in solaris both in sparc and x86. There is one issue of porting dosbox 0.73 in sparc. keyboard scancodes do not work well in default config in sparc. So i need to set 'usescancodes' to false in source code in case of sparc. Is it fine?

It's fine if you can assure that on a non-us keyboard everything works as
expected (sdl reports language-translated keycodes on some systems like
linux and always-us keycodes on others like windows).
The best-thing-to-do would of course be adding to the scancode mapping
in sdl_mapper.cpp (tables like sdlkey_map at the top of the file, and some
processing at the bottom).

Presently i'm doing it in a simple way. I'm checking system architecture in my Makefile and if i get 'sparc' then i'm applying a patch in dosbox source code. The patch is :
