problem with math library ?

[Naga Kalla]

Hi all,

I am using a sparc simulator. In order to run a normal C program on this
simulator, a set of libraries, gcc compiler, etc have been provided.
This was done quite some time back. But when i am using it right now, i
have a problem :

if i compile a program foo.c like :

gcc foo.c -lm

it compiles fine on my system. But when i use the compiler given with
the simulator, after the compilation step, i get the following problem
with the linker :

lib/libsim/libmath.a(sincos.o)(.text+0xc): undefined reference to
`__finite'
lib/libsim/libmath.a(__drem.o)(.text+0x8): undefined reference to
`errno'

How do i approach this problem ?Any suggestions would be greatly
appreciated.
