Help! I recently upgraded our DN10000 from 10.0 to 10.1, and
all the C math functions have disappeared. For example:
main()
{
float x, sin();
x = sin(1.0);
}
when compiled, gives the message:
% cc foo.c
undefined first referenced
symbol in file
matherr /usr/lib/crt0.o
sin foo.o
ld warning: Output file a.out not executable
The "matherr" object also appears in a console message
when I reboot the node. I get something like:
Loading Init.
Undefined Global "ldexp" referenced in /lib/libc
Undefined Global "ldexp" referenced in /lib/libc
Undefined Global "matherr" referenced in /lib/libc
I've called the hotline about this. The languages group
eventually gave up and declared that it was a system problem.
The system group has no idea what is going on. I can't
believe that this is happening on every DN10000 which is
running SR10.1.p! The library files /lib/syslib and
/lib/clib are there, but something must be missing. Any
help would be greatly appreciated!

For what it's worth, we don't have this problem - your
sample program compiled and ran fine. We are running 10.1.P.
The missing globals are all in syslib, not clib. You might
do a "bind /lib/syslib -glob" and see what's there. (Note
that is an Aegis /com/bind, not a Unix bind).

Find syslib in your AA and copy it into /lib. Reboot, et voila, your problem should be history.

Many thanks to all who have responded to my request for help with the missing math functions on the DN10000. The problem was solved for me by a very helpful Software Engineer from Apollo Toronto. It seemed that a beta C compiler I had tried out had clobbered /lib/syslib. This was know to be a problem with installing on a SR10.1 node, but I had missed the warning message sent out with the beta tape. I will be executed by a firing squad for this, as soon as I have finished documenting my code :-) --- Marc Majka - Altar Boy of Apollo

Any > help would be greatly appreciated! yep, it happened here to :-( We had to reinstall from our AA, the 10.0 version of syslib. However I'm informed that the system runs slower with this old syslib (any comments out there ??) - it sure seems like it does. Somebody has *really* goofed on this one ...... I hope it all gets properly rectified when we get (at long last) REAL compilers for the 10000. ian BTW has anyone seen the Omniback/8mm tape thingie for the 10000 yet ?? We are waiting for delivery on ours so I'm keen to find out about others experiences with it. -- Ian Hoyle /\/\ Computer Systems Superintendent / / /\ BHP Melbourne Research Laboratories / / / \ 245 Wellington Rd, Mulgrave, 3170 / / / /\ \ AUSTRALIA \ \/ / / / \ / / / Phone : +61-3-560-7066 \/\/\/ ACSnet : ianh@merlin.bhpmrl.oz.au Internet: ianh%merlin.bhpmrl.oz.au@uunet.uu.net
