This is probably fine.  These will be resolved in
io-pkt itself.  Our drivers and lsms have the
following in their Makefile to suppress these.

LDFLAGS+=-Wl,--allow-shlib-undefined

-seanb

AFAIK packfil.c is not QNX supported code so I have no idea what you're 
trying to do. But those symbols are in the stack. Did you want to build 
a dll or link your code in statically?

I see below that your x86/dll build is either not happening, or has 
happened successfully before. Note: With a dll you'll leave those 
symbols to resolve with the stack at load. You'll need to build with 
shared library options (see also Sean's post...).

As it is, looks like your x86/o build is trying to link a final 
executable "lsm" and is failing because it would need to link with the 
stack.

Hope this helps!
