I have been doing some porting from DEC Ultrix to Motorola System V/88K. It
seems that Ultrix is BSD in nature and Motorola is POSIX system V. I have
some source code written in c that uses the following functions:
getwd()
floor()
They do not seem to be supported in System V. The following seems to be the
output:
cc -O -DDIRENT -o xv xv.o xvmisc.o xv24to8.o xvgif.o xvpm.o xvinfo.o
xvc
trl.o xvscrl.o xvgifwr.o xvdir.o xvbutt.o xvpbm.o xvxbm.o xvgam.o xvfish.o
-lMr
m -lUil -lX11 -lXaw -lXm -lXmu -lXt -lXtm -lbsd -lci -lcrypt -lcs -lcurses -lg
-
lgen -ll -lmnt -lnls -lns -lnsl -lomalloc -lrobot -lsec -ltermcap -ltermlib -ly
undefined first referenced
symbol in file
_getwd xv.o
_floor xvgam.o
ld fatal: Symbol referencing errors. No output written to xv
*** Error code 13
Stop.
If any of you know what the equvalent of the above functions are for system V
I would appreciate it!!

For getwd(), getcwd() is the equvalent in System V(but it is slower because getcwd calls popen to excecute "sh -c pwd".)
