Hello all,
I'm trying to compile a large program wherein I had to choose a series of
options for my system (Linux/PC vs. SGI, etc). The entire output of the
compile is the following lines:
g++ -DNDEBUG -O3 -c -DWRITEPDBQSTATE main.cc
main.cc:60: declaration of C function `int gethostname(char *, int)'
conflicts with /usr/include/unistd.h:662: previous declaration `int
gethostname(char *, size_t)' here make: *** [main.o] Error 1
I am not a programmer, so this means nothing beyond the obvious "it screwed
up somewhere" to me. Compiler options I chose in the makefile are:
# Edit this Makefile to reflect your machine architecture.
#
# Specifically, change these variables:
# LIB, CSTD, CFLAGS, OPT, OLIMIT, LINT, LINTFLAGS, LINK, WARN, & CC. #
# If you need to use debugging or profiling, these should also be #
modified appropriately:
# DBUG & PROF
[...]
CC = g++
LIB = -lm -lg++
CSTD = $(DBUG) $(PROF) $(WARN)
CFLAGS = $(OPT)
OPTLEVEL = -O3
OPT = $(CSTD) $(OPTLEVEL)
OLIMIT = $(OPT)
LINKOPT = $(OPT)
LINK = $(LINKOPT)
LINT = lint
LINTFLAGS = $(LIB) -c
DBUG = -DNDEBUG
PROF=
WARN =
with the dependencies line being:
main.o : main.cc hybrids.h ranlib.h gs.h ls.h rep.h support.h main.h
constants.h autocomm.h dpftoken.h structs.h autoglobal.h autocomm.h
$(CC) $(OLIMIT) -c -DWRITEPDBQSTATE main.cc
Can anyone tell whether the error is an issue with my system setup and/or
these options, or is it likely a programming glitch? Is there more info I
need to show to determine this?
Thanks,
Kenward Vaughan
