RE: [TCLUG:6998] more compile help -- imsp

[Ben Luey <lueyb@carleton.edu>]

Thanks! I got it to compile! 

A few questions though. One, when I compiled I got:

prot.c:45: conflicting types for `sys_errlist'
/usr/include/stdio.h:553: previous declaration of `sys_errlist'
prot.c: In function `prot_settimeout':
prot.c:155: warning: passing arg 2 of `signal' from incompatible pointer
type
make: *** [prot.o] Error 1

and ended up commenting out line 553 from stdio.h  -- is there something
better to do?


imsp was loading signals.h. /usr/include/signals.h and
/usr/include/sys/signals.h (which are different) do not mention SIGEMT or
SIGSYS in them. So I commented them out -- is there a better way to fix
this? This is a default Mandrake 6.0 install.


Thanks though -- it compiled and I'm working on getting authorization to
work now.

It's better to spend the money we have now more wisely than to spend a lot
more money after the fact on the dysfunction we've created.
