<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I recently ported squeak to Syllable OS and it runs with
vm-display-null and vm-sound-null just fine. Now I would like to develop the
video driver for Syllable…unfortunately Syllable’s windowing system
is written in C++ and interfacing to it could be difficult (they may have a C
interface set up…I’ll check). As a backup I was wondering if I can
just use SDL by modifying the vm-display-custom?<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I tried to modify the vm-display-custom code and it compiles
fine with some SDL functionality but I have one weird problem. If I add any
external call into the sqUnixCustomWindow.c file then compile/link/install it,
the squeak module loader can’t find vm-display-custom anymore. I can
modify the file by adding some structures and functions local to the file but,
like I said, if I call outside this file (and then include -lSDL or whatever
when linking) then the loader just can’t even see vm-display-custom.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I can see display_custom and display_custom_itf with the
‘nm’ command and the format of the shared lib looks fine??? Does
the loader look for something really specific about the libs size or something
strange like that? I assume it dlopens() it.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>P.S. I am sure that I have all the libs and things in the
correct places because I can just recompile by commenting out my single
external function call, recompile, reinstall and things work fine.<o:p></o:p></span></font></p>
