[kln2-devel] kln2 - compiling problems (fwd)

[Marek W. <Mar...@fu...>]

Hi e-body,
Carlo had the same problems with compiling and here is his solution.

Mo, I hope this works for you too.

I solved them with some casts, below you can find the diff.
This compiles, but I couldn't test if it works as it should.
I used a cast to char*, so (as far as I know) in
	new_pos = (char *)old_point + n
the compiler adds to old_point n times the size of a char (wich is
platform dependent and != 1 byte)
so instead of

	memcpy((prefetch+prefetch_pos*(FRAG_SIZE)), buffer_raw, FRAG_SIZE);

there maybe should stay

	memcpy(((unsigned
char*)prefetch+(prefetch_pos*(FRAG_SIZE)/sizeof(char))), buffer_raw,
FRAG_SIZE);

** still a problem: I cannot manage to have MIDI playback running
this is probably a matter with my configuration...
I have an Intel i810 audio card, and I'm running a Mandrake 9.2 wich
choses by herself wich sound server to run (ALSA doesn't work)
(I have the same problem with rosegarden, but timidity should work, I
still have to try it)
