64位linux编译安装jpcap报错解决办法

/usr/bin/ld: /tmp/ccL2M6sC.o: relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC

修改jpcap-0.7/src/c 目录下的 Makefile 文件
添加编译选项 -fPIC

$(CC) $(COMPILE_OPTION) -fPIC -I$(JNI_INCLUDE) -I$(JNI_INCLUDE2)\
                 -I$(PCAP_INCLUDE)\

重新make就可以通过了
