Can anyone tell me where I’m going wrong please…
My code compiles and runs on SGI IRIX.
It compiles but fails to link on QNX.
My makefile for QNX says…
default: transmit
tcp.o: tcp.cpp tcp.h
cc -c tcp.cpp
transmit.o: transmit.cpp tcp.h
cc -c transmit.cpp
transmit: transmit.o tcp.o
cc -o transmit tcp.o transmit.o -lsocks
and the linker says…
cc -o transmit tcp.o transmit.o -lsocks

gethostbyname’
