I've finally got my application running under Rockbox on the G5 iPod,
and thought I'd send a note about how I got Rockbox installed. Much
easier than the Web page makes it look.
1) Connect the iPod to a Windows machine. Download the latest
iPodLinux installer and run it, thereby installing the l

Yes, that's what I'm doing now. Works fine, except that you have
multiple copies of the code.

I've been working on some Rockbox browsers for ebooks, targeting the
G5 iPod. They use standard libraries, like libpng and zlib. I've
developed rockbox-able versions of these, and would like to bundle
them up as shared libraries instead of statically linking them into
each plugin. Is there any s
Doesn't crash, but things don't seem to work quite right, either.
Needs more work.
Why doesn't the sector buffer in the "readwrite" function already do
the necessary buffering?

OK, I'll try it and report back.

If you build it, people will use it. I wrote a plugin last week that used it.
I liked the rewrite Jonathan posted.

Let me try :-).
The formula (in lcd-16bit.c)
lcd_getstringsize(str, &w, &h);
xpos = xmargin + x*w / utf8length(str);
ypos = ymargin + y*h;
seems to be a way of trying to come up with an average character cell
width the display. However
I've been looking at the implementation of lcd_puts_scroll() and
related functions on the lcd-16bit code. It's really odd. There's
really no good way to specify an X value other than 0.
The formula for vertical position of the line is just the (Y * font
height) + YMARGIN, so you can think of it

Thanks, yes, that seems clear. Are the formats that the LCD "likes"

Thanks.

But the value of "entries" is initialized only once, period -- when
the shared library is loaded into the simulator. So the second time
you run the viewer, in the simulator, it may have a bad value. I can
imagine a way this c

"get_pic_list" is invoked every time you invoke the viewer, isn't it?
I believe that when you run the simulator, the shared library
containing the viewer is loaded o
On the Mac, with the simulator, the simulator doesn't exit when told to.
Turns out there's some code in uisimulator/sdl/uisdl/gui_shutdown()
which hangs waiting for a semaphore to empty, for no particularly good
reason.
The following patch fixes that behavior.

But it has to be re-initialized when you re-enter "get_pic_list",
since the "file_pt" variable is re-initialized when you do that.

I'm using it in the simulator, under GDB, and conditions there might
be different from in a real device. But I can't see how

I've added a patchfile to the
http://www.rockbox.org/twiki/bin/view/Main/UiSimulator page (at the
bottom) which patches the CVS sources so that they build and run on
Mac OS X 10.4.6 with gcc 4.0.1. Someone probably wants to add them to
the source tree at some point before they get too stale.
