[SOLVED] compiling jpcap on 64bit system

_dunmer · 2009-02-26 20:32:48

hello

can i compile jpcap on arch x86_64?
because when i try it i get this error:

/usr/bin/ld: /tmp/ccWFe5Db.o: relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC
/tmp/ccWFe5Db.o: could not read symbols: Bad value
collect2: ld returned 1 exit status
make: *** [libjpcap.so] Error 1

i tried to serach web but i just found out that this is architecture issue but no solution..

edit:
if i use 32bit enviroment (http://wiki.archlinux.org/index.php/Arc … bit_system) to compile it will it wrok on my 64 bit?

Search for -fPIC compiler flag issues in our forums and mailing lists. Fix it in the corresponding Makefile. If you don't find it try export CFLAGS="$CFLAGS -fPIC" though this is not the proper way and slows it down more than needed.

Please also file an upstream bug.

this is whole makefile

JAVA_DIR = $(JAVA_HOME)

JNI_INCLUDE = $(JAVA_DIR)/include

# try to detect your OS using 'uname'
PLATFORM = $(shell "uname")

ifeq ($(PLATFORM), Linux)
    JNI_INCLUDE2 = $(JAVA_DIR)/include/linux
    COMPILE_OPTION = -shared -L.
    SUFFIX = .so
else
ifeq ($(PLATFORM), FreeBSD)
    JNI_INCLUDE2 = $(JAVA_DIR)/include/freebsd
    COMPILE_OPTION = -shared -L.
    SUFFIX = .so
else
ifeq ($(PLATFORM), SunOS)
    JNI_INCLUDE2 = $(JAVA_DIR)/include/solaris
    COMPILE_OPTION = -G
    SUFFIX = .so
else
ifeq ($(PLATFORM), Darwin)
    JNI_INCLUDE2 = /System/Library/Frameworks/JavaVM.framework/Headers 
    COMPILE_OPTION = -bundle -framework JavaVM
    SUFFIX = .jnilib
endif
endif
endif
endif

# Specify where pcap.h is
PCAP_INCLUDE = /usr/include
#PCAP_INCLUDE = /usr/include/pcap

#CC = cl
CC = gcc

all: libjpcap.so

libjpcap.so: JpcapCaptor.c JpcapSender.c JpcapWriter.c\
             packet_arp.c packet_datalink.c packet_icmp.c packet_ip.c\
             packet_ipv6.c packet_tcp.c packet_udp.c 
        $(CC) $(COMPILE_OPTION) -I$(JNI_INCLUDE) -I$(JNI_INCLUDE2)\
         -I$(PCAP_INCLUDE)\
        JpcapCaptor.c JpcapSender.c JpcapWriter.c\
          packet_arp.c packet_datalink.c packet_icmp.c packet_ip.c\
          packet_ipv6.c packet_tcp.c packet_udp.c\
        -o libjpcap$(SUFFIX) -lpcap
clean:
        -rm libjpcap$(SUFFIX)

witt thie make file i get this error:

[dunmer@joybox c]$ make

collect2: ld returned 1 exit status
make: *** [libjpcap.so] Error 1

when i add -fPIC to CFLAGS it doesn't do anything and i get the same output

somebody tell me to chanege Linux part of make file like this:

ifeq ($(PLATFORM), Linux)
JNI_INCLUDE2 = $(JAVA_DIR)/include/linux
-- COMPILE_OPTION = -shared -L.
++ COMPILE_OPTION = -shared -fPIC -L.

whit this a i get another error:

[dunmer@joybox c]$ make

                 -I/usr/include\

          packet_ipv6.c packet_tcp.c packet_udp.c\

nothing i could find about -fPIC helped me..

ok, i give up

can anybody tell what have i do to use this library compilated on 32bit system? some 32bit enviroment?

_dunmer · 2009-02-28 13:15:06

i created 32bit enviroment using this wiki page: http://wiki.archlinux.org/index.php/Arc … bit_system and compiled it there..
it's working or at least it looks working.

Arch Linux
