Hi everybody,
I'm trying to compile a program that uses log,exp,sen,and cos functions from
MATH.H, but I get "/tmp/cca020491.o(.text+0x424): undefined reference to `sen'"
and the same for the other functions.
What can i do?

Pablo.

There's an excellent "GCC-HOWTO", that you should read, by Daniel Barlow,
here's the URL:

Try using 'sin' instead of 'sen'. There's no transcendental math function
named 'sen'. Also, make sure that you link against the math library (-lm, see
the C or GCC FAQ).

Also important to check if the libm.so point to the correct and existing
library. It cost me 45 minutes (at 1.00 am) last night before I found that one
out.

A small / BIG problem can ya please help..... with my "mount" setup....

I am using S.u.S.E. Linux 5.3 with KDE... and I like it... But I can't
mount
my SCSI CD-ROM.... My controller is supported and I did use it to
Install linux
but now I can't mount it. In "YaST" for the mount points I can see it
but it is grayed out ?

I treed mounting it form the X Term ( I am ROOT user) with,
"mount -t iso9660 -r /dev/cdrom /mnt/cdrom" and I get Not a valid block
device ?

I also did edit my "fstab" file an the line for my CD-ROM is there....
"/dev/scd0         /cdrom          iso9660       ro,noauto,user 0   0"

so what is going on, do I need to boot with a SCSI kernel, I am booting
with
a IDED kernel because I do not have any SCSI hard drives.... also I
can't mount my darn
floppy drive as well ??? what is going on ???

Rich     - please E-mail if you can....
