As for the construct_response, I think the easiest way to debug this is by looking what exactly is on the stack as the function is run.

If you don't have it, then QNX probably does things differently. I'd
need to know how though.
==
i have got "ldd in shell script"
so, we may see:
localhost% ldd libSDL.so
       libm.so.2 =>    /lib/libm.so.2
       libph.so.2 =>   /usr/lib/libph.so.2
       libGL.so.2 =>   /usr/lib/libGL.so.2
       libasound.so.2 =>       /lib/libasound.so.2
       libc.so.2 =>    /proc/boot/libc.so.2
localhost% ldd libvorbis.so
       libc.so.2 =>    /proc/boot/libc.so.2
localhost% ldd libogg.so
       libc.so.2 =>    /proc/boot/libc.so.2

so, we can see, while 3rd-party made libSDL is linked properly, libs that came with distribution are linked really strangely.
so, we will have to have that QNX) part in config...

==
It's all in the manual page.
==
:p QNX does not have man by default... :p

==
printf works like the libc printf() function. The first argument is the
format string specifying how to interpret the rest of the options.
==
yes. and what do these 2 strings mean? i am curious, and printf is curious too...
" ? %*i. %s %s\n"
" ? %-*s ? %s (N/A) %s\n"

==
But you're right. It does look like this is what generated the 'format
errors', not sed. Why it only does that for the debug menu, I don't
know.
==
I have changed these format strings and everything went ok.
why only in menu? because, only in menu there are such strings. have not tried menus other than debug...

oh, btw. I have got OpenGL devel packages and made it with OpenGL support.
It DOES run and work but it goes TERRIBLE ;(

and, our bug:
==
Breakpoint 1, construct_response (buf=0x8339f80 "", R=58) at src/sc2code/commglue.c:240

240             fprintf(stderr, "DEBUG: We've entered into construct_response!\n");
(gdb) info stack
#0  construct_response (buf=0x8339f80 "", R=58) at src/sc2code/commglue.c:240
#1  0x08088140 in Intro () at src/sc2code/comm/comandr/comandr.c:633

#3  0x08053396 in InitCommunication (which_comm=350231303) at src/sc2code/comm.c:2162

#7  0xb823088f in ?? ()
#8  0xb8230a7e in ?? ()
(gdb) next
242             va_start (vlist, R);
(gdb) next
244             fprintf(stderr, "DEBUG: R = %d\n", R);
(gdb) print vlist
$1 = 0x7f84aee "o\a@\201\b\b\200\2373\b:"
(gdb) ptype R
type = short unsigned int
==
what is strange:
1)vlist is junk
2)type of R is short unsigned int, but later program will try to R = va_arg(vlist, int);
3)i fail to understand what does work wrong...

Ok, then I'll add that. Is the -I/usr/local/include and -L/usr/local/lib necessary in QNX, or did you just copy them from the line from FreeBSD (on Linux, these paths are used automatically).

Quote

yes. and what do these 2 strings mean? i am curious, and printf is curious too...
" ? %*i. %s %s\n"
" ? %-*s ? %s (N/A) %s\n"

%*i is like %i (take an integer), but it reads the length of the field from an additional argument. The minus sign in the second line means left-align instead of right-align.
If any of those what your printf chokes on, I can easilly work around it.
Just let me know which one (or maybe both).

The main menu also is a menu, that's why I was confused. I forgot for a moment it was a different kind of menu.

OpenGL only helps if you have hardware acceleration. In Linux, only a few video drivers support it. I suspect it's even worse on QNX.

Quote

1)vlist is junk

It's not. It's not supposed to be point to a string. It's pointing to somewhere on the stack.

Quote

2)type of R is short unsigned int, but later program will try to R = va_arg(vlist, int);

That itself is not a problem. The number fits in a short.
What I'm wondering though if whether a complete has really been pushed on the stack. (see below)

Quote

3)i fail to understand what does work wrong...

I suspect it is a variable size issue of some sort. The easiest way to check would be to check what's on the stack.
Could you do the following from gdb, from within construct_response:
(gdb) x/40xb &R
and also:
(gdb) p sizeof no_but_well_help0

Also, I'd like to know what architechture this is? IA-32?

I noticed you visited the IRC channel, but left again after a minute.
I was there, but like many other people, we're often working on something, and don't check the IRC session every minute. It's still the best place to find us, and probably the fastest way to solve this.

==
You dont need. Bacause, QNX is very strange on paths anyway:
libs should be taken from /<arch>/usr/lib/ and /usr/local/lib (libvorbis would be here by default)
includes - from /opt/include

thats do work without -I -L as i see...

==
%*i is like %i (take an integer), but it reads the length of the field
from an additional argument. The minus sign in the second line means
left-align instead of right-align.

==
they _both_ does not work.
but, all menus looks correctly with:
==
                       if menu_have_choice "$MENU" "$OPTION"; then
                               printf "  %i. %s %s\n" "$I" \
                                               "$SELECTED" "$TEMP_TITLE"
                       else
                               printf "  %s  %s (N/A) %s\n" "-" \
                                               "$SELECTED" "$TEMP_TITLE"
                       fi
==
=>

We does not have more than 10 options, and not going to, so we can use KISS method.

==

==
Yea. We have it and it does work. How does it work - it's not our problem, SDL version looks good...
BTW, SDL itself is still beta under QNX.
"We call it beta cause it's betta when nothing"... :p
==
In Linux, only a few video drivers support it. I suspect it's even worse on QNX.

Sure. Qhile it's enough for Q3, btw ^^
