I am trying to call a fortran subroutine from a C program.  I tried this
on the DS3100 and DS5000 running ULTRIX 4.0.
When I link the programs together, I get the following error message.
I tried several libraries but in vain.  Can someone, please, tell me
what I am doing wrong, in other words, what I ought to do.

Here is what I did:

f77 -c desp56.f
cc eeg-new.c desp56.o -lI77 -lF77 -lm
>>ld:
>>Undefined:
>>sinf
>>sqrtf
>>cosf
>>expf
>>logf

I tried altering the order of the libraries.  I also tried a lot of illogical
things (I just wanted to exhaust all possible alternatives!).

Thanks.
